Answer:
3.545 represents a value of 0.04
The total amount of money that Jeff has is $20
total fraction of his expenses on lunch and movies is:
(2/5+1/8)
=21/40
the remaining fraction is:
1-21/40
=19/40
thus the amount of cash that Jeff was left with will be:
19/40×20
=$ 9.5
Answer:
12 inches
Step-by-step explanation:
So you know that the perimeter of a picture frame (a rectangle) is 2 widths plus 2 lengths.
Let x= lengths and w= widths
From the question we already know that w=7, so we can set up an equation that says:
2x + 2w = 38
2x + 2(7) = 38
2x+14 = 38
2x +14 -14 = 38-14
2x = 24
2x/2 = 24/2
x= 12
Since x= lengths =12
the length of the frame is 12 inches.
