Answer: C. 100

Step-by-step explanation:

If  the large tank is flowing at a constant rate of  -6 per minute then we have to know that the water is moving from the tank. So is asking how many water will be left in the tank after 25 minutes.

You could use the equation

y = -6x  + 250  where y is the amount of water left in the tank and x is the number of minutes.

So if x is 25 then plot it in and solve for y.

y = -6(25) +250

y = -150 +250

y= 100

Three times a larger number is 30 more than 5 times a smaller number. The sum of the larger number and 5 times the smaller numbe
kicyunya [14]

Answer: Smaller number = 6

Larger number = 20

Step-by-step explanation:

Let the smaller number be x.

Let the larger number be y.

Three times a larger number is 30 more than 5 times a smaller number. This will be:

3 × y = (5 × x) + 30

3y = 5x + 30 ...... i

The sum of the larger number and 5 times the smaller number is 50. This will be:

y + 5x = 50 ...... ii

From equation ii

y + 5x = 50.

y = 50 - 5x ...... iii

Put the value of y = 50 - 5x into equation i

3y = 5x + 30

3(50 - 5x) = 5x + 30

150 - 15x = 5x + 30

150 - 30 = 5x + 15x

120 = 20x

x = 120/20

x = 6

The smaller number is 6

Note that y + 5x = 50

y + 5(6) = 50

y + 30 = 50

y = 50 - 30

y = 20

The bigger number is 20
