Answer:
n=6
Step-by-step explanation:
(n-18)/3 = -4
multiply by 3
n-18 = -12
add 18
n = 6
Well you can either think of actually dividing the fraction or reduce to lowest forms which is 1/2. then from 1/2 you can either divide that or just say it is .5.
Perform indicated multiplication:
11c+3(-5c)+3(4d)
11c-15c+12d combine like terms
(11c-15c)+12d
-4c+12d factor
4(3d-c)
Answer:
34
Step-by-step explanation:
F(x) = 2x^3 - 7x + 1
Let x= 3
F(3) = 2* 3^3 - 7*3 + 1
= 2 * 27 -21+1
= 54 -21 + 1
= 34
