Answer:
3x + 1 = 7
x = 2
Step-by-step explanation:
equation for the hanger diagram
3x + 1 = 7
Subtract 1 from both sides
3x = 6
Divide both sides by 3
x = 2
2,200*14=30,800
2,000*13=26,000
14+13=27
30,800+26,000=56,000
Your answer is C, 13(:
Answer:
#6:
A: 
Step-by-step explanation:
Points: (3, -5) and (-7, -1)
Slope Formula: 



Jason = J, Kim = K
K+325m = J
K = 4.2 km
convert km to m by multiplying by 1000
4.2km * 1000 = 4200m = K
so just plug in your values to get your answer : Jason ran 4525 meters
4200m + 325 = 4525m
