Answer:

(x,y)=(10,6)

Step-by-step explanation:

Substitute the value of x into the equation {4x+ 5= 70

                                                                       {x= 6+ 2/3y

solve the equation 4(6+2/3y) +5y = 70

substitute the value of y into the equation y=6

solve the equation x=6 + 2/3 times 6

A possible solution is x= 10

Check the solution (x,y) = (10 ,6)

Simplify {4 times 10 + 5 times 6 =7

              {3 times 10 - 2 times 6 = 18

The ordered pair is a solution {70 = 70

                                                   {18 =18

1.7cubic feet per minutes Given that one cubic foot is equivalent to approximately 7.48 gallons what would the pump rating be in
son4ous [18]

Answer:

449 per hour

Step-by-step explanation:

First of all we know the question is asking us to round to the nearest tenth and find the rate of gallons per hour.

First:

Know there are 60 minutes in one hour

Second:

Take 7.48 and multiply it by 60

Third:

This should give you---448.8

Which is correct, but we are not done

Fourth:

Round to the nearest whole number

448.8

8 is closer to 10 than it is to 1 so we add 0.2

Which gives us 449

Five:

Just add the "per hour"

Six:

Your answer is---449 per hour---
