Steps to solve:
3(5x - 8) = 6x + 39
~Distribute left side
15x - 24 = 6x + 39
~Add 24 to both sides
15x = 6x + 63
~Subtract 6x to both sides
9x = 63
~Divide 9 to both sides
x = 7
Best of Luck!
Answer:
24 Years
Step-by-step explanation:
Rule of 72 is an approximation that you can use to estimate the time it will take for something to double in value at a compound rate of interest
use the following equation
72/(i*100)
we have
72/(.03*100)
72/3=24
Hello there! Your answer should be 4 mph. Reasoning:
2 = (20 - x) * t
3 = (20 + x ) * t
Time is the same for both equations. Solve for T.
2/(20-x) = 3/(20+x)
the answer is 4 mph.
Please tell me if I was right!
Positive+positive= positive
negative+negative=positive
-7+10= negative
4/6 + 2/6= positive
-9.5+4= negative
