Answer:
f = 65
Step-by-step explanation:
6.50*21+f=201.50
We need to isolate f
1. multiply 6.50 by 21. 6.50 * 21 = 136.5
136.5+f= 201.50
2. Since 136.5 is positive and not being subtracted we will...
Subtract 136.5 from both sides
136.5-136.5=0+f
201.50-136.50 = 65
thus leaving f = 65
Perimeter is how far around, so you are going to total the 2 lengths and 2 widths. A way to write that is P=2l+2w.
P = 2(5 5/8) + 2 (6 1/4)
2(5 5/8) = 10 10/8 or 11 2/8 or 11 1/4
2(6 1/4) = 12 1/2
P = 11 1/4 + 12 1/2
P = 23 3/4
Answer:
Step-by-step explanation:
1. The first step is to get 14.8 on the other side. It is a positive number which means that you have to subtract 14.8 on both sides:
<u>-14.8 -14.8</u>
2. The second step is to get x by itself. Right now it is being multiplied by x so to get it by itself you have to do the opposite of multiplication which is division, so you will divide 8.4 by both sides:
Answer: 88/102
