Answer:
he has 80 cents
Step-by-step explanation:
dime=10 cents
I'm guessing that the hidden question is how many dimes does Omar have? because this is the first thing I asked myself when solving this equation.
So how many dimes does Omar have?
5 + 3 = 8
Now we know that one dime = 10 cents, so to find the amount of money in cents, all we need to do is multiply 8 * 10
8 * 10 = 80
Omar has 80 cents

Andrew rounded the number 672 726 to the nearest hundred thousand he wrote 672 000 find and correct his mistake
Answer:700000
Step-by-step explanation:
The number of zeros for hundred thousand is five .Thus100,000
So you start by counting the zeros from the right hand side of the figure 672000 to the left till your counting reach 5.
So wen you get to the fifth zero check the number that it falls on . Thus 7 will be that number,And since it's greater than 5 you add 1 to the prefix of the 7 which is 6 to be become 6+1=7 , hence the answer is 700000 to the nearest hundred thousand.
Answer:
700 000
Step-by-step explanation:
Andrew rounded the number 672 726 to the nearest hundred thousand.
Hth TH Th H T O
↓ ↓ ↓ ↓ ↓ ↓
6 7 2 7 2 6
now round the number to nearest hundred thousand.
hundred thousand digit in 672726 is 7
If rounding number is greater than equal to 5 then next number increase by 1.
If rounding number is less than 5 then next number does not change.
here rounding number is 7 > 5
So, next digit 6 change to 7
Rounded number = 700 000
672 726 → 700 000
Andrew did
672 726 → 672 000
Mistake: Rounded to thousand instead of hundred thousand
Correct rounded number = 700 000

The sum of the measures of the angles of a triangle is 180. The sum of the measures of the second and third angles is five times the measure of the first angle. The third angle is 16 more than the second. Let x, y, and z represent the measures of the first, second, and third angles, respectively. Find the measures of the three angles.
X measures 30°, Y measures 67°, and Z measures 83°.
Since the sum of the measures of the angles of a triangle is 180, and the sum of the measures of the second and third angles is five times the measure of the first angle, and the third angle is 16 more than the second, for find the measures of the three angles, the following calculation must be performed, posing linear equations:
X + Y + Z = 180 Y + Z = 5X Z = Y + 16
X + 5X = 180 6X = 180 X = 180/6 X = 30
Y + Y + 16 = 5 x 30 2Y + 16 = 150 2Y = 150 - 16 Y = 134/2 Y = 67
Z = 67 + 16 Z = 83
Therefore, X measures 30 °, Y measures 67 °, and Z measures 83 °.

Let x, y, and z represent the measures of the first, second, and third angles of the triangle. We can create a system of equations to find the values of x, y, and z. Solving this system, we find that x = 28, y = 32, and z = 48.
Explanation:Let's use x, y, and z to represent the measures of the first, second, and third angles, respectively.
The sum of the measures of the second and third angles is five times the measure of the first angle, so we have the equation y + z = 5x.
The third angle is 16 more than the second, so z = y + 16.
Since the sum of the measures of the angles of a triangle is 180, we have the equation x + y + z = 180.
Now we can solve these equations to find the measures of the three angles.
Substituting z = y + 16 into the equation y + z = 5x, we get y + y + 16 = 5x, which simplifies to 2y + 16 = 5x.
Substituting z = y + 16 into the equation x + y + z = 180, we get x + y + y + 16 = 180, which simplifies to x + 2y + 16 = 180.
Now we have a system of equations:
2y + 16 = 5x
x + 2y + 16 = 180
Solving this system, we find that x = 28, y = 32, and z = 48.

What is the value of a in the equation 3 a plus b equals 54, when b equals 9?
Answer:
a = 15
Step-by-step explanation:
Given
3a + b = 54 ← substitute b = 9
3a + 9 = 54 ( subtract 9 from both sides )
3a = 45 ( divide both sides by 3 )
a = 15
An equation is formed when two equal expressions. The value of a in the equation 3a+b=54, when b equals 9 is 15.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
The given statement "3 a plus b equals 54" in terms of the equation can be written as,
3a + b = 54
Given an equation 3a+b=54. Also, the value of b in the given equation is 9. Therefore, the value of a in the given equation can be written as,
3a + 9 = 54
Subtract 9 from both sides of the equation,
3a + 9 - 9 = 54 - 9
3a = 45
Divide both the sides of the equation by a,
3a/3 = 45/3
a = 15
Hence, the value of a in the equation 3a+b=54, when b equals 9 is 15.

Annette, Barb, and Carlita work in a clothing shop. One day the three had combined sales of $1480. Annette sold $120 more than Barb. Barb and Carlita combined sold $280 more than Annette. Write and solve a linear system to find out how much did each person sold.
Answer:
The quantity sold by Annette was $600
The quantity sold by Barb was $480
The quantity sold by Carlita was $400
Step-by-step explanation:
Let
x ----> quantity sold by Annette
y ---> quantity sold by Barb
z ---> quantity sold by Carlita
we know that
[tex]x+y+z=1,480[/tex] ----> equation A
[tex]x=y+120[/tex] ----> equation B
[tex]y+z=x+280[/tex] ----> equation C
substitute equation C in equation A and solve for x
[tex]x+(x+280)=1,480[/tex]
[tex]2x=1,480-280[/tex]
[tex]2x=1,200[/tex]
[tex]x=\$600[/tex]
Find the value of y
[tex]x=y+120[/tex]
[tex]600=y+120[/tex]
[tex]y=600-120=\$480[/tex]
Find the value of z
[tex]x+y+z=1,480[/tex]
[tex]600+480+z=1,480[/tex]
[tex]1,080+z=1,480[/tex]
[tex]z=\$400[/tex]
therefore
The quantity sold by Annette was $600
The quantity sold by Barb was $480
The quantity sold by Carlita was $400
The solution involves setting up a system of three linear equations based on the given problem. By solving these equations methodically, we find that Barb, Annette, and Carlita sold $400, $520, and $560 of clothing respectively.
Explanation:The problem involves setting up and solving a system of linear equations. Here's how we approach it:
Let's denote Barb's sales as B, Annette's sales as A, and Carlita's sales as C.The total sales are given to be $1480, so we have our first equation as A + B + C = 1480.The problem states that Annette sold $120 more than Barb. This gives us another equation: A = B + 120.It is also said that Barb and Carlita combined sold $280 more than Annette, hence the third equation: B + C = A + 280.Now we have a system of three equations which we can solve step-by-step. Firstly, substitute A from the second equation into the first and third one, providing us with two new equations: B + 120 + B + C = 1480 and B + C = B + 120 + 280. These simplify to 2B + C = 1360 and B = 400. Substituting B = 400 into the equation 2B + C = 1360 gives C = 560.Last, we substitute B = 400 into the second equation A = B + 120, which simplifies to A = 520.So, Barb sold $400 of clothing, Carlita sold $560, and Annette sold $520.

N.) = 47.7° O.) = 36° P.) = 90°
Step-by-step explanation:
All triangles are 180°
So:
A.) 72 + 68 = 140 180 - 140 = 40
The little boxes in the triangle indicates that the angle is a right angle. Right angles are 90°
B.) Is a right angle
C.) 36.5 + 90 = 126.5 180 - 126.5 = 53.5

E.) Is a right angle
F.) 95 + 32.1 = 127.1 180 - 127.1 = 52.9
G.) Is a right angle
H.) 30.4 + 90 = 120.4 180 - 120.4 = 59.6
To find angle I you have to find angle J first. So, because there is a box. That indicates that both angle equal 90°.
So you have to subtract H from 90° H = 59.6
J.) 59.6 - 90 = 30.4
I.) 30.5 + 30.4 = 60.9 180 - 60.9 = 119.1
K.) 45 + 45 = 90 180 - 90 = 90
L.) 33 + 75 = 108 180 - 108 = 72
M.) 37 + 35.7 = 72.7 180 - 72.7 = 107.3
N.) 92.3 + 40 = 132.3 180 - 132.3 = 47.7
O.) 54 + 90 = 144 180 - 144 = 36

Shannon and Kelly spent $135 on gift certificates for their friends during the holidays. If this amount is 5/7 their total spending money, how much spending money did they originally have? Set up an equation and solve.
Answer:
$189
Step-by-step explanation:
Let their total amount of spending money be x
given that $135 they spent is 5/7 of their total spending money,
mathematically:
135 = (5/7) x (multiply both sides by 7)
135 (7) = 5x
945 = 5x
5x = 945 (divide both sides by 5)
x = 945 / 5
x = 189
Shannon and Kelly originally had $189 as their spending money.
Explanation:Let x be the original amount of spending money.
According to the problem, Shannon and Kelly spent $135 on gift certificates, which is 5/7 of the total spending money.
This can be represented by the equation: 5/7 * x = $135.
To solve for x, we can multiply both sides of the equation by 7/5 to get x = $135 * 7/5 = $189.

reads page 47, Wednesday he decides to skip all remaining odd pages and just reads all
other even pages.
How many pages are still left James does not read yet?.
Answer:
103
Step-by-step explanation:
Unread pages = (a) 1 - 12; (b) 32 - 46; (c) odd numbered pages from 48 - 200
The number of pages in each range is:
(a) n₁ = 12 - 1 + 1 = 12
(b) n₂ = 46 - 32 + 1 = 15
(c) n₃ = 200 - 48 + 1 =153
Half the pages are odd-numbered.
153/2 = 76½.
200 and 48 are both even so there are more even-numbered pages in the range.
There are 77 even-numbered and 76 odd-numbered pages.
The total of unread pages is

Answer:
Step-by-step explanation: Would the answer be y=0.80x because the x=10 and y=8??
Answer:
[tex]y=0.80x[/tex]
Step-by-step explanation:
Let x represent number of hours spent writing and y represent total pages written.
We have been given a graph that represents how the length of Julia's essay depends on the number of hours she spends writing.
First of all, we will find slope of the line using point (0,0) and (5,4).
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\frac{4-0}{5-0}[/tex]
[tex]m=\frac{4}{5}[/tex]
[tex]m=0.80[/tex]
Now, we will substitute the slope in the slope-intercept form of equation [tex]y=mx+b[/tex], where,
m = Slope,
b = The y-intercept.
We can see that y-intercept is 0.
Therefore, our required equation would be [tex]y=0.80x[/tex].

They let you see how one fraction compares to another for one. Say you had 2/5 and 3/7 it may be tricky to tell which is bigger, but having the tiles will let you see that 3/7 is slightly bigger. And there are many many more complicated examples. So if you know which is bigger you will know subtracting the smaller one will keep it positive, while if you subtract the larger from the smaller one it will be negative.
Also, you can then find equivalent tiles. In the example I gave you would be able to see 2/5 = 14/35 and 3/7 = 15/35. Which are like fractions you can subtract simply.
Final answer:
Fraction tiles are a useful tool for subtracting unlike fractions by helping you visualize the process and find a common denominator, making the subtraction of different sized pieces understandable and accurate.
Explanation:
Fraction tiles are a visual and intuitive tool to help you understand how to subtract unlike fractions. When subtracting fractions with different denominators (unlike fractions), you cannot simply subtract the numerators because they represent different sized pieces. Fraction tiles help by providing a visual representation of different fractions and showing how they can be combined or separated into equivalent amounts with a common denominator.
To subtract unlike fractions effectively using your intuition and fraction tiles, first make sure that each fraction is represented by tiles that are all of the same size, which represent the common denominator. Once you have the common denominator for both fractions, you can easily remove the number of tiles corresponding to the smaller fraction from the larger one. The remaining tiles will show you the difference between the two fractions.
This approach will guide you in constructing the right rules for subtraction. Remember, the denominators in a fraction tell us how many equal parts the whole is divided into, while the numerators tell us how many parts we have. By using fraction tiles and aligning them to a common denominator, our intuition helps us understand the process mathematically, giving us confidence in the rules of subtracting fractions.
Prime fractorization of 47?
Answer:
1 times 47
Step-by-step explanation:
Final answer:
The number 47 is a prime number; therefore, its prime factorization is the number 47 itself.
Explanation:
The prime factorization of a number is breaking it down into prime numbers that, when multiplied together, give the original number. For the number 47, it is actually a prime number itself, which means its prime factorization is simply 47. Prime numbers are numbers greater than 1 that have no divisors other than 1 and themselves. Therefore, since 47 cannot be divided evenly by any other numbers aside from 1 and 47, it does not have a prime factorization other than being considered a factor of itself.
