Answer:
Sofias solution is correct.
Step-by-step explanation:
First of all you do not need two sets of the same equation.
y=-1.5x + 5.7
y = 0.5x + 0.3
If you graph the y-intercepts first then graph the slope for the equation then you will get the right answer.
1) Graph 5.7 on the y-axis. | Then graph -1.5x going down on the y-axis and then go to the right on the x-axis.
Do the same for the other equation and you will get a solution of (2.7, 1.65) since they will intersect there.

Answer:
The length is 9 units.
Step-by-step explanation:
x will be our length so we get:
x*(x-6)=27
You can just try the factors of 27 as x.
Let's guess x is 9
9*(9-6)=27
9*3=27
Which is true, so the <u>length must be 9</u> and the width must be 6.
Answer:
Plug 3 into everywhere there is an 'x', and solve.
