TEA [102]2 years ago

You want to start by subtracting 5 from both sides to get 2/3x=-8/3 then cross multiply to get whole numbers which is 6=-24x then your gonna want to isolate the variable so divide both sides by -24 to get 6/-24=x then you can simplify to x=-1/4

The width of a rectangle is 15 ft. shorter than its length. Its perimeter is 262 ft. Let l equal the length of the rectangle.
masha68 [24]
Let the length be l.
For now, let's make the width be w. 
Additionally, l = w + 15. Using this equation, width can also be written as l - 15. 
The perimeter of a rectangle is length + length + width + width. This can also be written as l + l + (l-15) + (l-15) = l + l + l - 15 + l - 15 = 4l - 30.
Using this equation:
4l - 30 = 262
4l = 292
l = 73

4(w + 15) - 30 = 262
4w + 60 - 30 = 262
4w + 30 = 262
4w = 232
w = 58

A washer and a dryer cost $772 combined. The washer cost $72 more than the dryer. What is the cost of the dryer
melamori03 [73]
Dryer cost represented by x
Then, the washer costs (x + $72)
Together, they cost (x) + (x+72) = $772
2x+72 = 772
[subtract 97 from both sides]
x = 350
[divide both sides by 2]

The dryer cost $350

The washer cost $422.

Together, they cost $772
