Please someone help me finish filling in the rest :( feel like I’m finna cry

Let the number be x in all those expressions.

15 - x = 20 - 7

or, x = 15 - 13 = 2

x + 2 = 16 + 3

or, x = 19 - 2 = 17

13 - 6 = x - 9

or, 7 + 9 = 16 = x

10 • 6 = 15 • x

or, 60/15 = 4 = x

10 ÷ x = 20 ÷ 4

or, 5 × 10 = 50 = x

18 • x = 16 • 9

or, x = 144 / 18 = 8

16 • 9 = 18 • x

or, x = 144 ÷ 18 = 8

10 ÷ 2 = x ÷ 2

or, x = 10 × 2 = 20

$9.89

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)

9.90 = p x 0.015

9.90 - 0.015 = p

9.89 = p
