Step-by-step explanation:
Set up the equation, 15/20 = 10/x, and then use cross mutiply to solve it.

-90=
-18
Step-by-step explanation:
you need to use quadratic formula and you will find square root a negative ( -9 ), which is an imaginary no.
square root (-9) = 3i
No because root(3)(x+8+1) is equal to x^3 -9 and (x-1)^3+8 is equal to root (3)(√x−8−1)
To find the current salary, we take 10% of $25 (the raise), then add it back into the current salary.
Current salary = (25×10%) + 25
= (25 × .10) + 25
= 2.50 + 25
= $27.50
So his raise was 2.50 and he now makes $27.50
