Answer:
Step-by-step explanation:
In order to solve for x, she had to first subtract 6 on both sides of the equation. Then divide by 5 on both sides of he equation. After the division part, she was able to successfully isolate x.
The equation she had to solve was (C) 5x+6=21
First step: Subtracting 6 on both sides of equation resulted in
5x = 15
Second step: Dividing both sides of the equation by 5 resulted in
x = 3
Answer:
ince you are just starting, i would say anywhere from 40-45 minutes, you should be averaging about 7-8 minutes per mile.
Step-by-step explanation:
For sake of convenience, reverse the series, then it would be:
21,19,17.....7
a=21, d = -2,
s(4) = 4/2 (21+15)
s(4)=2(36)
s(4) = 72
36/48 simplified is 3/4
divide both by 12
36÷12
3
48÷12
4
I'm glad to hear that, but where is the math problem?
