Answer:
The correct answer is 53.
Step-by-step explanation:
When subtracting by a negative number, the subtraction symbols cancel and we are left with an addition problem. See the work below.
10 - (-43)
10 + 43
53
Answer:
53
Step-by-step explanation:
To solve this problem you must apply the proccedure shown below:
1. You have the following exercise:
[tex]10-(-43)[/tex]
2. You must multiply the signs. When you multiply two negative signs the result is positive:
[tex]10+43[/tex]
3. Now, you can make the addition:
[tex]10+43=53[/tex]
Use this figure to find each ratio in simplest form.
We know that
triangles ADE and ABC are similar triangles
so, the ratios of their sides must be same
now, we will find value of sides
we are given
AD=12
DB=6
AE=14
EC=7
[tex]AB=AD+DB[/tex]
now, we can plug values
[tex]AB=12+6[/tex]
[tex]AB=18[/tex]
so, we can get ratio
[tex]\frac{DE}{BC} =\frac{AD}{AB}[/tex]
now, we can plug values
[tex]\frac{DE}{BC} =\frac{12}{18}[/tex]
So, the ratio in simplest form is
[tex]\frac{DE}{BC} =\frac{2}{3}[/tex]..............Answer

What is the prime factorization of 2x3x5x7
This is already in prime factored form. If you multiply 2, 3, 5, and 7 you get 2*3*5*7 = 6*35 = 210
So if your book asked "what is the prime factorization of 210?" then the answer would be 2*3*5*7
I'm using the asterisk symbol * in place of x because x is often used as a variable in algebra.
The prime factorization of 2x3x5x7 is simply 2x3x5x7 itself because these are all prime numbers. Prime numbers are numbers that have only two factors: 1 and the number itself. In addition, the product 2x3x5x7 equals to 210, so the prime factorization of 210 is also 2x3x5x7.
Explanation:The prime factorization of a number is a product of the prime numbers that can multiply together to create the original number. In this case, the product 2x3x5x7 is already a multiplication of prime numbers. Hence, the prime factorization of 2x3x5x7 is simply 2x3x5x7.
Prime numbers are the numbers that have only two factors: 1 and the number itself. Examples of prime numbers are 2, 3, 5, and 7.
On the other hand, the product 2x3x5x7 equals to 210. So the prime factorization of 210 is also 2x3x5x7.

Step-by-step explanation:
The approximate distance in km between her house and her job is 9 km.
What is scaling ?
It is the technique to resize drawing with comparing to actual size of object which uses proportion or ratio. For example, Mapping of earth, drawing prototype of automobiles
It is given that :
The distance on a map between a student’s house and her job is 6 cm.
also, on the same map, the distance between her house and her school is 8 cm.

Izzy is Iago's little sister. She is counting her coins. Izzy finds that she has three more quarters ($0.25) than she has dimes ($0.10), twice as many nickels ($0.05) as she has dimes, and four times as many pennies ($0.01) as she has dimes. With a total of $7.61 in coins, how many coins of each type does Izzy have?
Lzzy has three more quarters ($0.25) than she has dimes ($0.10), twice as many nickels ($0.05) as she has dimes, and four times as many pennies ($0.01) as she has dimes.
Let us assume number of dimes = x.
"Three more quarters than dimes" would be = (x+3) quarters .
"Twice as many nickels as dimes " would be = (2x) nickels.
"Four times as many pennies as dimes" would be =(4x) pennies.
Total value of all coins = $7.61.
We can setup an equation now.
0.10*x + 0.25(x+3) + 0.05(2x)+0.01(4x)=7.61.
Let us simplify the equation.
0.10x + 0.25x + 0.75 + 0.10x + 0.04x = 7.61
0.49x + 0.75 = 7.61.
Subtratcing 0.75 from both sides, we get
0.49x = 6.86
Dividing both sides by 0.49, we get
x= 14.
Therefore,
Number of dimes = x = 14.Number of quarters = (x+3) = 14+3 = 17.Number of nickels = 2x = 2*14 = 28.Number of pennies = 4x = 4*14 = 56.What are the 6 trigonometry functions

Daniel biked to the park. On the way, he stopped for a soda, then continued to the park. After playing a game of catch, Daniel biked home. Between which two points did Daniel more than likely stop for a soda?
A) between points B and C
B) between points C and D
C) between points D and E
D) between points E and F
the distance from home would not change while he was stopped, so it would be a flat line. the two possibilities are B and C or D and E. He stopped for a soda then played catch (which would also be a flat line since he would be the same distance from home) so it must be B and C
Choice A
Answer:
A
Step-by-step explanation:
because D and E is when he's playing catch and right after he went home.

A girl's feet are negative 4 over 6 yards from the surface of a pool. A boy's feet are negative 1 over 6 yards from the surface of the pool. Determine whose feet are closer to the surface.
The girl's feet are closer to the surface of the pool because negative 4 over 6 > negative 1 over 6.
The boy's feet are closer to the surface of the pool because negative 4 over 6 < negative 1 over 6.
The girl's feet are closer to the surface of the pool because negative 4 over 6 < negative 1 over 6.
The boy's feet are closer to the surface of the pool because negative 4 over 6 > negative 1 over 6.
Given the distances of -4/6 yards (for the girl's feet) and -1/6 yards (for the boy's feet) from the pool's surface, the boy's feet are closer to the pool's surface because -1/6 is greater than -4/6 in the negative number system.
Explanation:In this problem, we are comparing the positions of the girl's feet and the boy's feet relative to the surface of the pool. We are given that the girl's feet are at a distance of negative 4 over 6 yards from the pool's surface and the boy's feet are at a distance of negative 1 over 6 yards from the pool's surface. The negative numbers here indicate that the feet are below the surface of the pool.
We know that a number closer to zero has a higher value in the negative number system. Therefore, -1/6 is greater than -4/6. So, the boy's feet are closer to the surface of the pool because negative 4 over 6 (the girl's feet) is less than negative 1 over 6 (the boy's feet).

Evelyn is making a candy that contains 25% dark chocolate and the rest milk chocolate. The candy has 3 pounds of milk chocolate.
Part A: Write an equation using one variable that can be used to find the total number of pounds of dark chocolate and milk chocolate in the candy. Define the variable used in the equation. Hint: 0.25x represents the number of pounds of dark chocolate in the candy. (5 points)
Part B: How many pounds of dark chocolate are present in the candy?
Part A:
If 25% is dark chocolate and the rest is milk chocolate then, dark + milk = all
25% + milk chocolate= 100%
Subtract 25% from both sides and 100 minus 25 is 75 so, milk chocolate is 75% of all the chocolate.
Now, if there is 3 pounds of milk chocolate then 3 pounds= 75%.
You would divide by 3 so, 75 divided by 3 is 25.
1 pound or lb= 25% which us the amount of dark chocolate that there is.
Now, we know that there milk chocolate is 75% and dark chocolate is 25% of all the chocolate.
M= pounds of milk chocolate
D= dark chocolate
Equation: m divided by d or m/d= 75 divided by 25 or 75/25 or m/d=3 and m=3
3 divided by d or 3/d=3
3=3d
D=1
Part B:
There is 1 pound of dark chocolate in the candy.
Hope this helps! :)
Final answer:
The equation to find the total pounds of dark chocolate and milk chocolate in the candy is 0.25x + 3 = x. There are 4 pounds of dark chocolate present in the candy.
Explanation:
Part A: Let's define the variable x as the total number of pounds of dark chocolate and milk chocolate in the candy. Since the candy contains 25% dark chocolate, we can represent the pounds of dark chocolate as 0.25x. The candy also has 3 pounds of milk chocolate, so we can represent the pounds of milk chocolate as 3. Therefore, the equation is: 0.25x + 3 = x.
Part B: To find the pounds of dark chocolate in the candy, we can solve the equation from Part A. First, subtract 0.25x from both sides: 3 = 0.75x. Then, divide both sides by 0.75 to solve for x: x = 4. Therefore, there are 4 pounds of dark chocolate present in the candy.

What is the value of x in the equation 1/5 x – 2/3y = 30, when y = 15?
1/5x - 2/3(15) = 30
Answer is: by simplifying both sides of the equation, then isolating the variable.
x = 200
1/5 x – 2/3y = 30
1/5 x – 2/3 (15) = 30
1/5x - 10 = 30
1/5x = 40
x = 200
