Answer:
-8
Step-by-step explanation:
(7)*(-8) = -56
(-56) - (-8) = -48
Answer:
24
Step-by-step explanation:
1 / 4 x + 18 = x
x / 4 + 18 = x
x = x / 4 + 18
x - x / 4 = 18
( 4x / 4 ) - ( x/4 ) = 18
( 4x - x ) / 4 = 18
3x / 4 = 18
3x = 18 * 4
x = ( 18 * 4 ) / 3
= 6 * 4
x = 24
Do you mean simplified ratio of 50:30, because if you did then the simplified ratio of 50:30 would be 5:3. Divide both numbers by 10.
