Answer:
(3 x 5) + (6 x 5) = (16 x 5) – (7 x 5)
(3 x 8) + (10 x 8) = 13 x 8
Step-by-step explanation:
(3 x 5) + (6 x 5) = (16 x 5) – (________ x 5)
(15) + (30) = 80 – ( ____ x 5)
45 = 80 – ( ____ x 5)
We need to subtract 35 from 80 for it to equal 45
7 x 5 = 35, so fill in 7 in the blank
45 = 80 – (7 x 5)
45 = 80 – 35
45 = 45
(3 x 8) + ( ________ x 8) = 13 x 8
(24) + ( _______ x 8) = 104
We need to add 80 to 24 for it to equal 104
8 x 10 = 80, so fill in 10 in the blank
(24) + (10 x 8) = 104
(24) + (80) = 104
104 = 104
