Step-by-step explanation:
35g=5 g=1/7
15s=120 s=8
Answer:
r = -1/2
Step-by-step explanation:
3(5 + 4r) = -18r
15 +12r = -18r by distributive property
15 = -12r - 18r
15 = -30r
r = - 1/2r
A (solution) is a point of intersection. If the lines have different slopes then they will have one solution. If they have the same slope, then they will have either infinite or no solutions, depending on the y intercepts.
These equations have different slopes, therefore the system has 1 solution.
Answer:
60
Step-by-step explanation:
19+30-(-11)
Distribute the negative sign.
19+30+11=60
