Answer:
r = -1/2
Step-by-step explanation:
3(5 + 4r) = -18r
15 +12r = -18r by distributive property
15 = -12r - 18r
15 = -30r
r = - 1/2r
Answer: Isolate the variable by dividing each side by factors that don't contain the variable.
Exact Form:
r=−411
Decimal Form:
r=−0.¯¯¯¯36

Answer:
x=0
Step-by-step explanation:
24+x=9x+4*6
First, simplify 4*6 into 24:
24+x=9x+24
No, subtract 24 on each side:
x=9x
This wouldn't be possible except with one number that could represent x:
0.
If we substitute in 0 for x, we get:
0=9*0
9*0 is 0:
0=0

Answer:
C
Step-by-step explanation:
To find the sum of f and g then add the expressions f(x) and g(x).
f(x) + g(x)
10-2x + 7x+5
10+5x+5
15+5x
This means that (F+g)(x) = 15+5x.

-3x² - 9x = 0
Divide each side of the equation by -3 :
x² + 3x = 0
Factor the left side:
x (x + 3) = 0
This is true if x=0 or if x=-3 .
