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.
Answer:
Class 2 has 210 house points.
Step-by-step explanation:
630/3 = 210
1 = 210 x 2 = 420
2 = 210
420 + 210 + 630
325 miles total.
23.95x4 =95.8
200-95.80
=$104.20
104.20 divided by.32 is 325.6 so in total 325 miles.
