Plug in x = 7. Then use the order of operations (PEMDAS) to simplify
y = 11 - 5*x
y = 11 - 5*7 .... x has been replaced with 7 (since x = 7 is given)
y = 11 - 35
y = -24
$79.69 is the answer

because 8, 9-10th graders watched and 7 didn’t
The answer to this question is zero (0)
Well we can find out how many used books there are by subtracting 8 from 13 which gives us 5. Then we put that in a ratio for all to used it would be 13:5 or 13/5
Used to new would be 5:8 or 5/8
