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

blem 5: James reads a 200-page book. 'On Monday he reads page 13 through page 31, next day he
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
12 + 15 + 76 = 103

5x – 8 > 40
Answer:
x>48/5 or x<-3/2
Step-by-step explanation:
Solve for x
a) 12x + 7 < -11
12x < -11-7
12x < -18
x < -18/12
⇒ Simplify: divide the numerator by 6
x < -3/2
b) 5x – 8 > 40
5x > 40+8
5x > 48
x > 48/5
Therefore, x>48/5 or x<-3/2.
how do you solve -2/5x -9<9/10
Answer:
x > -99/4
Step-by-step explanation:
I must assume that you meant (-2/5)x -9<9/10.
This inequality has 3 terms. The LCD is 10. Multiply each term by 10 and reduce the result:
10(-2/5)x - 10(9) < 10(9/10), or:
-4x - 90 < 9
Adding 90 to both sides results in:
-4x < 99
Here we must divide by a negative number (that is, by -4). This requires reversing the direction of the inequality sign:
x > -99/4 is the final solution.

$40 will be taken off the bill and you will be paying a total of $120.
Multiply 160 by .25 to find the amount taken off ($40), and then subtract from the total to find the amount that you will be paying ($120).
Have a great day!
Answer:
You will pay $120
Step-by-step explanation:
There are many methods in solving this percentage equation, but this is by far my favorite. Here is how it works.
1.Take 160, the original amount. 160
2.Then take the percent amount .25
and convert into decimal. ---------------------
3. Multiply the numbers 40.00
4. Subtract the product from 160
original amount, 160. - 40

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.

Yung bought $4.60 worth of bubble gum. Each piece of gum cost $0.10. How many pieces of bubble gum did Yung buy?
Answer:
46 pieces
Step-by-step explanation:
We get n (number of pieces) as follows
n = (4.6 $) / (0.1 $/piece) = 46 pieces
Answer:
Yung bought 46 pieces of bubble gum for $4.6
Explanation:
We are given that each piece of gum cost $0.1 and that he spent $4.6 on gums
To get the number of gums he bought, we will simply use cross multiplication as follows:

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.
