Step-by-step explanation:
a
7
because 4a + 7 - 7
35 - 7
equals 4a
28
and 4a/4
28/4
equals a
7
Okay if there are 8 teachers and 6 reams of paper you would have to divide 6 by 8 and you would get 0.75
6/8= 0.75
each teacher would get 0.75 (3/4) of a ream of paper
It would be d because you would subtract 52 from 17 to get the answer then add the number you got to 17 to get 52.
