This is a linear relationship. The slope-intercept form of the linear equation is:

Where,
- m is the rate of change (positive if increasing rate and negative if decreasing rate)
- c is the y intercept, or the initial value
<u><em>Rate of change is 2.5 quarts per minute (it is decreasing so m is -2.5)</em></u>
<u><em>Initial value is 50 quarts, so c is 50.</em></u>
Plugging in the values we get
.
Changing variables to w instead of y and t instead of x, gives us,
. Where w is warts of water left in the tub and t is the time in minutes.
There is no viable solution when t=30 because at t=20, w=0 (
). It means after 20 minutes, there is no water left. So t=30 minutes doesn't make sense.

When
, there is no VIABLE solution
Answer:
17
Step-by-step explanation:
n = 17
n - 7 = 10
Carry over the - 7
n = 7 + 10
n = 17
Answer:
The answer is 1 cup of sugar
Step-by-step explanation:
x = 2 x 1.5/3
x = 3/3
x = 1 cup of sugar

Answer:
The answer is $97.35
Step-by-step explanation:
This because you would need to multiply 75x1.298 to get your answer and your conversion method is multiplying so your answer is $97.35
Hope this helps and have a great day!!
I'm not to sure if I know the other ones but number 12th Is 6
Step-by-step explanation:
Since the two lines intersect at point Q(x,y) the x & y values of both lines must be equal at point Q. so 3x+14=7x-10. Solving for x yields x = 6.
