Answer:
a. 13; Equation = 2N - 7 = 19
b. 2; 8 - 3N = 2
Step-by-step explanation:
a. 2N - 7 = 19
- 2N - 7 + 7 = 19 + 7
<u>- 2N</u> = <u>26</u> = 13
2 2
b. 8 - 3N = 2
8 - 8 - 3N = 2 - 8
<u>- 3N</u> = <u>-6</u> = 2
-3 -3

Answer: 47
Step-by-step explanation:
Let´s:
t=time when the both runners coincide.
velocity=distance/time ⇒ distance=velocity x time
distance traveled by Christy=0.12 t
distance traveled by Cindy=0.22 t
Becuse Christy starts the race with an advantage of 1.5 km de distance from Cindy´s position the distance would be : 0.12 t + 1.5
We would have to solve the following equation:
0.12t+1.5=.0.22t
0.22t-0.12t=1.5
0.1t=1.5
t=1.5/0.1
t=15
Answer: In 15 minutes Cindy will catch Christy
