Answer:
The monthly growth rate is 2.1%
Step-by-step explanation:
To find the monthly growth rate, we have to consider what is inside the bracket
Mathematically, what we have in the bracket should be written as;
1 + r
Thus;
1 + r = 1.021
r = 1.021-1
r = 0.021
This is same as 2.1%

Answer:
x = -10
Step-by-step explanation:
expand
simplify 36 - 4.5x + 36 to -4.5x + 72
simplify 102 - 7.5x - 60 to -7.5x + 42
add 7.5x to both sides
simplify -4.5x + 72 + 7.5x to 3x + 72
subtract 72 from both sides
simplify 42 - 72 to -30
divide both sides by 3
simplify 30/3 to 10
Answer: x = -10
