Question

Complete each equation with a number that makes it true. 8______=40 8+______=40 21______=7 21−______=7 21______=7

Answer 1

blank one is 5

blank two is 32

blank three is 3

blank four is 14

blank five is 3

Answer 2

8*5 = 40 8+32 = 40 21/3 = 7 21-14 = 7 21/3 = 7

Explanation:

40/8 = 5

8 + x = 40 40-8 = x = 32

21x = 7 x = 7/21 = 1/3

21 - x = 7 21 - 7 = x = 14

21x = 7 x = 7/21 = 1/3
