What are you trying to find?
Answer: 16 boxes and 6 football cards in each box.
Step-by-step explanation:
Here total football cards rob has = 96
And, He filled 9 boxes with basketball cards.
Also, Rob filled 3 fewer plastic boxes with football cards than basketball cards.
Therefore, football cards in each boxes = 9 - 3 = 6
Thus, the number of boxes he can fill with football cards = 96/6 =16
Answer:
3 * (x + 7)
Step-by-step explanation:
Mark number as x
Then the sum of a number and seven is x + 7
Three times x + 7 can be written as
3 * (x + 7)
Parentheses mean that we first add x and 7 and then multiply their sum by 3
Alternatively you can write it as 3x + 21, since
3 * (x + 7) = 3 * x + 3 * 7 = 3x + 21

Answer:
y=x+w/5
Step-by-step explanation:
x=5y-w
step 1: bring the additional letters/numbers next to the "5y" over to the left
x+w= 5y
step 2: divide the numbers and letters on both sides of the "=" by 5 to only get the letter y
x+w/5= y
step 3: swap them over
y= x+w/5
(we can't get an answer from x+w/5 because the terms are unlike, therefore we keep it as a fraction
