Answer:
Carlos has practiced piano for 
hours.
Carlos needs to practice 
hours.
Step-by-step explanation:
We have been given that Carlos wants to practice piano 2 hours each day. He practices piano for 3/4 hour before school and 7/10 hour when he gets home.
First of all, we will find piano practiced before school and after school by adding both amounts as:
Make a common denominator:
Add numerators:
Therefore, Carlos has practiced piano for hours.
Now, we will subtract from 2 find number of hours Carlos needs to practice to reach his goal.
Therefore, Carlos needs to practice hours before going to bed in order to meet his goal.
your answer to that division problem is 35.9
×≥ 26/7 is the answer.
hope it helps!
Answer: square root of 10
Step-by-step explanation:
If you have other questions like find the distance of AB or A’B’ they are the square root of 10 for this same triangle so therefore this distance would be the same.
If y is 5 when x is 2.5 and y varies directly with x, find y when x is 10.
The term "y varies directly with x" means that the formula is a direct variation. We need to look for the constant of variation.
y = kx ; where k is the constant of variation.
k = y/x
k = 5/2.5
k = 2
We then use the direct variation formula to get the value of y when x is a certain number.
y = kx
y = 2 * 10
y = 20
