X = k x y
21 = k x 3
k = 7
x = 7y
x = 7(10)
x = 70
Heyy thanks for you question you answer would be P=750
Hope this helps!!
14+10y > 3(y+14)
14+10y > 3y + 42
-3y -3Y
14 + 10y - 3y < 42
-14 -14
10y - 3y >42 - 14
7y > 28
Y> 4
Subtract normally as if 32.6 is 316 and 1.9 is 19. Then you move the decimal point two places to the left of the answer
the answer is 29.7
