Answer:
9/7 + 3/14b - 9/14c
Step-by-step explanation:
See image below:)
12x^3 +2x^2-30x = 8
2x( 6x^2 +x -15) = 8
so 2x= 8, x=4
(2x) ( 2x-3) ( 3x+5) = 8
2x-3 = 8
2x= 11
x= 5.5
3x+5=8
3x= 3
x=1

Answer:
2662.50
Step-by-step explanation:
Let s represent her old salary. Then we have ...
0.065s = 162.50

new salary = old salary + raise
new salary = 2500 +162.50
new salary = 2662.50
