Answer:
k = 12
Step-by-step explanation:
Given in the question,
Cost of the the movie tickets is proportional to the number of tickets sold.
Cost of movie tickets (C) ∝ number of tickets sold (T)
C ∝ T
C = kT
Here 'k' is a proportionality constant.
Since, line given in the graph passes through a point (5, 60)
60 = k(5)
k = 
k = 12
Therefore, value of proportionality constant is 12.
for the first part:
Let's solve for x.
−x+3y=14
Step 1: Add -3y to both sides.
−x+3y+−3y=14+−3y
−x=−3y+14
Step 2: Divide both sides by -1.
−x/−1 = −3y+14/−1
x=3y−14
Answer:
x=3y−14
Second part:Let's solve for x.
3x−3y=−6
Step 1: Add 3y to both sides.
3x−3y+3y=−6+3y
3x=3y−6
Step 2: Divide both sides by 3.
3x/3= 3y−6/3x=y−2
Answer:
x=y−2
The table of the tolls for Henderson is the direct variation since the cost is proportional to the miles traveled.
Answer:
It will take rob 7 minutes to climb the stairs tomorrow.
Step-by-step explanation:
1000/25=40
Rob climbed 40 stairs per minute
280/40=7
Therefore, it will take rob 7 minutes to climb 280 stairs.
Answer:
16/25
This is because you have to make it into a percent which is 64% then you have to do 64/100 and simplify it.
