The length of a rectangular picture frame is 4 inches less than three times the width. The perimeter is 136 inches. Find the len
natulia [17]

Answer:

The width of the rectangle is 18 inches, and the length is 50 inches

Step-by-step explanation:

We can designate a variable, x, to represent the width of the rectangle.  To represent the length and widths of the rectangle, we can say that the length is 3x-4 and the width is just x.  We can then write an equation for the perimeter and solve:

2(3x-4) + 2x = 136

6x - 8 + 2x = 136

8x - 8 = 136

8x = 144

x = 18

To calculate the length

(3x - 4)

3(18) - 4 = 50 in

Lamar works as a tutor for $7 an hour and as a waiter for $8 an hour . this month he worked a combined total of 92 hours at his
ira [324]

t is the number of hours Lamar worked as a tutor 
We know that he worked for 92 hours total, so he worked 92-t hours as a waiter.

So his earnings are: 7t + 8(92-t) = 736 -t dollars

This expression seems logical as if Lamar worked 0 hours as a tutor and 92 as a waiter his earnings would be 8*92 = 736
If he worked as a tutor for 92 hours it would be 7*92= 644 
736-92= 644 
So our expression seems to be working.
