Answer:
y = -56
Step-by-step explanation:
The equation for direct variation is
y = kx where k is the constant of variation
y = -8 x
We know x =7
y = -8*7
y = -56
50+2x=100
-50 -50(subtract 50 from both sides)
2x=50 (divide both sides by 2)
x=25
Answer:
its the one where the line starts at 50

Answer:
He can purchase 300 white baloons.
Step-by-step explanation:
150$ is 15000 cents
15000 = 60b + 30w
b being number of blue baloons,w number of white baloons and 60 and 30 prices in cents
15000 = 60*100 + 30w
15000 - 60*100 = 30w
15000- 6000 = 30w
30w = 9000
w =300
number of white baloons is 300
