First, you want to establish your equations.
L=7W-2
P=60
This is what we already know. To find the width, we have to plug in what we know into P=2(L+W), our equation to find perimeter.
<span>60=2(7W-2+W) </span>
<span>Now that we only have 1 variable, we can solve. </span>
First, distribute the 2.
60=14W-4+2W
Next, combine like terms.
60=16W-4
Then, add four to both sides.
64=16W
Lastly, divide both sides by 16
W=4
To find the length, we plug in our width.
7W-2
7(4)-2
28-2

Answer:
y =
x + 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (0, 1) and (x₂, y₂ ) = (3, 3) ← 2 points on the line
m =
= 
Note the line crosses the y- axis at (0, 1) ⇒ c = 1
y =
x + 1 ← equation of line

Answer:
Amy worked 47 1/2 (47.5) hours
Step-by-step explanation:
(22.25) (40) = $890
1,173.50 - 890 = $ 283.50
283.50/37.80 = 7 1/2 hours
