Answer:
Length = 16.3 in and Width = 12.3 in
Step-by-step explanation:
Let's name L the length and W the width of the rectangle. We can then write equations describing the statements given:
"<em>the length of a rectangle is 4 more than the width</em>"
L = W + 4
"<em>the perimeter of the rectangle is 57.2 inches</em>"
2 L + 2 W = 57.2
(where we used the formula for the perimeter of the rectangle equal to twice the rectangle's length plus twice the rectangle's width)
Now we use the first equation to substitute for L in the second one:
2 ( W + 4) + 2 W = 57.2
use distributive property to remove parenthesis
2 W + 8 + 2 W = 57.2
combine like terms
4 W + 8 = 57.2
subtract 8 from both sides
4 W = 57.2 - 8 = 49.2
divide both sides by 4 to isolate W
W = 49.2 / 4 = 12.3 in
Now we use this result in the first equation we wrote, to find L
L = W + 4 = 12.3 + 4 = 16.3 in
Therefore : Length = 16.3 in and Width = 12.3 in
The equation that represents this situation is F = 6 m + 10
They drove 8 miles
Step-by-step explanation:
The given is:
1. Happy Cab gets paid $10 for each pick up
2. He gets paid $6 for each mile afterwards
3. The total fair was $58
Let us write the equation
∵ The happy cab gets paid $10 for each pick up
∵ He gets paid $6 for each mile
∵ They drove m miles
- Assume that the total fair is F
∴ F = 6 m + 10
The equation is F = 6 m + 10
∵ The total fair F was $58
∵ F = 6 m + 10
∴ 58 = 6 m + 10
- Subtract 10 from both side
∴ 48 = 6 m
- Divide both sides by 6
∴ m = 8
∵ m is the number of miles
∴ They drove 8 miles
They drove 8 miles
