Answer:

Both equations cancel each other out

Step-by-step explanation:

18x + 15 - y = 0

5y = 90x + 12

You want to use the substitution method for this system of equations because the y can easily be isolated in the first equation. Just add y to both sides so that the y variable is isolated. You will have y = 18x + 15. Substitute that equation into the second equation and solve for x. So you will have           5(18x + 15) = 90x + 12.

Use the Distributive Property to get rid of the parenthesis.

90x + 75 = 90x + 12. Subtract 90x from both sides. There is no value for x as the 90x's cancel each other out. And we all know that 75 does not equal 12

Find the following dates in the units given:
11Alexandr11 [23.1K]

Answer and step-by-step explanation:

a.  4 litres in 5 minutes (litres per minute)

4 litres per 5 minutes means 4/5 litres per 1 min = 0.8 litres per minutes

b. 12 litres in 45 minutes = 12/3 litres in 45/3 minutes = 4 litres per 15 minutes

60 minutes = 4*15 minutes

4 * 4 = 16 litres per hour

c. 800 kilowatt hours in 2 months

1 year = 12 months = 2*6 months

kilowatt per year = 800 * 6 = 4800 kilowatt per year

Hope this helped :3
