Answer:

130 gallons initally, losing approx. 1.33333 gallons per minute, will be empty in approx 97.5 min

Step-by-step explanation:

1: y-intercept = (0, 130)

2: take two points (0, 130) & (30, 80)

use slope equation (80 - 130)/ (30 - 0) = -40/30 = -4/3

3: line equation is y=-4/3x+130

make y=0

0=-4/3x+130

-130=-4/3x

-130/-4/3=x

97.5=x

kap26 [50]

Answer:

40 problems in 100 minutes

Step-by-step explanation:

This is a ratio problem.

You first divide 30 minutes by three to get how many problems she can do in 10 minutes. What you do to one side you do to the other side. So then, you should have 4 problems in 10 minute. Then, you multiply 10 by 10 and 4 by 10 to get 40 problems in 100 minutes.

5 is the coefficent of y if you simplify and 3 is the constant

Step-by-step explanation:

7y-2y=5y. The coefficient is the number that goes with the variable, or letter, such as y. The constant is the number that does not have any coefficients attached to it.
