What you’re doing is breaking it down into its parts and writing it into an equation that way long hand.
3 + .4 + .00 + .005
Answer:
Multiply equation
by 5 and
by 4
Step-by-step explanation:
Given:
Equations are 
To find: constant by which each equation should be multiplied to eliminate the variable
in the given system of equations
Solution:

Multiply equation (i) by 5 and (ii) by 4 to get the following equations:

On subtracting these equations, we get

So, the variable
gets eliminated

Answer:

20 gallons of water is leaked after an hour.
Step-by-step explanation:
Water is leaking at a constant rate of 1/3 gallon per minute.
a) We have to write a linear equation in two variables that show the amount of water, w, in gallons, that is leaked from the faucet after t minutes.
So, the equation is
......... (1) (Answer)
b) Now, if t = 1 hour i.e. 60 minutes, then from equation (1) we can write
gallons.
Therefore, 20 gallons of water is leaked after an hour. (Answer)
Slope = (Y2 -Y1) ÷ (X2 -X1)
Slope = (1 -7) / (10 -1)
Slope = -6 / 9 = -0.6666666666666666
