Riley Beard · Answer 1

3 is the missing number

Step-by-step explanation:

8 * 5 = (5 * 5) + (_ * 5)

40 = 25 + (_ * 5) - Subtract 25 from both sides

15 = _ * 5 - Divide both sides by 3

3 = missing number

Sage Booth · Answer 2

8x5=40 5x5=25 40-25=15 15/5 is 3 therefore the missing number is 3

8*5 = (5*5) + (_*5) find the missing number

85 = (55) + (_*5) find the missing number
