Answer:
System of equations:
L = 5W + 7
2W + 2L = P
L = 62 cm
W = 11 cm
Step-by-step explanation:
Given the measurements and key words/phrases in the problem, we can set up two different equations that can be used to find both variables, length and width, of the rectangle.
The formula for perimeter of a rectangle is: 2W + 2L = P, where W = width and L = length. We also know that the L is '7 more than five times its width'. This can be written as: L = 5W + 7. Using this expression for the value of 'L', we can use the formula for perimeter and solve for width:
2W + 2(5W + 7) = 146
Distribute: 2W + 10W + 14 = 146
Combine like terms: 12W + 14 = 146
Subtract 14 from both sides: 12W + 14 - 14 = 146 - 14 or 12W = 132
Divide 12 by both sides: 12W/12 = 132/12 or W = 11
Put '11' in for W in the equation for 'L': L = 5(11) + 7 or L = 55 + 7 = 62.

Answer:
B
Step-by-step explanation:
The graph begins up and ends down. This means as x heads into negative infinity the graph continues up, up and up towards infinity. While x heads to positive infinity on the right side of the graph, the graph heads down, down, and down towards negative infinity. See graph below.
It is given that a home phone company charges by the minute.
It is given that Last month phone used was 125 minute
And it is also given that Last month bill came = $37.50
Now we have to calculate money charged per minute
Money charged per minute = 37.5 / 125 = $0.3
Now for this month time we have got = 175 minute
So total bill for this month will be =0.3 * 175 = $52.5
55+8.5x=123
Let x equal the number of days she rented the bike.
