Tasya [4]
Here in this case the answer is "a". The way to find the percentage is to add all the numbers you have which is $49. And then you need to use it to divide it with the percentage you need for the number. Which in this case you are searching for shoelaces and it $4. So you divide the cose of the shoelaces $4  to the total amount $49. And then you multiply by 100 to get the percentage. If you round it off the the tenth place you should get 8.2%

Evaluate x-y/5 when x is 23 more than 3 times y and y=6
posledela

Answer:

7

Step-by-step explanation:

1) "x is 23 more than 3 times y" is the same thing as "x = 23 + 3y"

REMEMBER: when you see "is" replace is with an equals sign.

2) Solve for x with your new equation.

3) Plug 6 into the y ("y = 6")

x = 23 + 3 x 6... x = 23 + 18... x = 41

4) Plug in your variables, and evaluate.

(41 - 6)/5... 35/5... 7!
