Answers

Answer 1
Answer: Here is the answer.


x = number of Cierra's purses

y = number of Aisha's purses

Equation =

y/2 + 3 = x

12/2 + 3 = x

6 + 3 = 9

Cierra has 9 purses

Rewrite 9.524 as a mixed number in lowest terms.

Answers

9.524=9+0.524=9+(524)/(1000)=9(524)/(1000)=9(524:2)/(1000:2)=9(262)/(500)=9(262:2)/(500:2)=\boxed{9(131)/(250)}
I believe that would be 9 & 131/250Because you start with 9& 524/1000 cut that in half would be 9& 262/500 cut that in half would be 9& 131/250

Hello can anyone help me on the next four math questions please ?1)5(x+2)
2) 4(2x+3)
3) 8(x+2)
4) 5(7x+4) thanks !!!

Answers

5(x + 2)
= 5(x) + 5(2)
= 5x + 10

4(2x + 3)
= 4(2x) + 4(3)
= 8x + 12

8(x + 2)
= 8(x) + 8(2)
= 8x + 16

5(7x + 4)
= 5(7x) + 5(4)
= 35x + 20
5(x+2)=5x+10\n4(2x+3)=8x+12\n8(x+2)=8x+16\n5(7x+4)=35x+20

suppose you have 192 marbles in groups of 15 marbles each. Find the number of groups of marbles that you have. Write the quotient with the remainder written as a fraction. Explain wha th faction part of your answer means.

Answers

so if you have 192 marbles and you want to group them in groups of 15 marbles each
you would see how many times 15's there are in 192 or how many 192's would go into 15

so 192/15 or 
12 and 12/15

The correct answer is:

12 12/15, or 12 4/5.

Explanation:

15 goes into 192 12 times. 15(12) = 180. This leaves us a remainder of 192-180 = 12. This gives us 12 12/15.

Both 12 and 15 can be divided by 3; (12÷3)/(15÷3) = 4/5.

This gives us 12 4/5.

Answer:

x = 20

Step-by-step explanation:

Turn all the numbers into fractions with the same denominator.

6.75 = (46)/(8)

13(1)/(4) = (53)/(4) × (2)/(2)  = (106)/(8)

(46)/(8) + (3)/(8)x = (106)/(8)

Subtract 6.75 from both sides

(3)/(8)x = (60)/(8)

Then multiply both sides by 8

3x = 60

Then divide both sides by 3 to get x

(3x)/(3) = (60)/(3)

Difference between 645 and 738

Answers

when someone asks about the difference between two numbers, they are asking you to subtract one number from the other.  This sentence can also be written as:

  738 - 645 = ?

The answer therefore is 93
Hi,

I'm not sure if you want to find the DIFFERENCE between 645 & 738 or 738 & 645. So Below I have done both of them below:- 

645 - 738 = -93

If someone gave you 645 candies, and then someone else said you better give me 738 candies. So, in the end you would have -93 candies left. 

738 - 645 = 93

If someone gave you 738 candies, and then someone else said you better give me 645 candies. So, in the end you would have 93 candies left. 

Hope I helped:P
