PLEASE HELP MEEEEeeee
Evgesh-ka [11]
Based on the graph shown, the intersection is (1.231, -0.452). 1.231 acts as coordinate x of the intersection, and -0.452 acts as coordinate y of the intersection.

In the equation
\frac{1}{2}x-1.0675=3x-4.145
the solution is the value of x. So the solution of the equation is the value of x. So, we use coordinate x of the intersection to find the solution of the equation, that is 1.231.

Final answer: 1.231

A pump fills 25 of a tank in 23 hour. At this rate, how much of the tank will the pump fill in an hour?
Sophie [7]

60% or 3/5 of the tank will be filled in an hour.

The pump will fill 2/5 of the tank in 2/3 hours.

In order to find out how much of the tank will be filled in an hour, use direct proportion and assume portion of the tank that will be filled up in an hour is x.

<em>2/5 of tank        :            2/3 hours </em>

<em>x of tank            :             1 hour </em>

Cross multiply to get:

2/3x = 2/5

x = 2/5 ÷ 2/3

x = 2/5 x 3/2

= 0.6 of the tank

= 60%

= 3/5 of tank

In conclusion, 60% of the tank will be filled in an hour.
