The length is two inches less than five times the width. This means
Length (L) = 5w - 2. (Does this make sense? You calculate 5 times the width and then minus 2)
Then we know the perimeter of a rectangle is 2(L+w) so
Perimeter = 2(5w-2 + w) = 2(6w-2) = 12w - 4 (so C and D are both correct because they are equal)
We check the other two options manually,
A: 2(5w-2)+2w = 10w-4+2w = 12w - 4 (so A is correct because it equals D which also equals C)
B: w+w+5w+5w-2 = 12w - 2 (which does not equal any of the other options)
So correct answers are A, C and D because they are all equal.
Answer:
The answer is D.
Step-by-step explanation:
Answer:
38 Quarters
Step-by-step explanation:
D=number of dimes; Q=number of quarters=D+3
.
$0.10D+$0.25Q=$13
$0.10D+$0.25(D+3)=$13
$0.10D+$0.25D+$0.75=$13
$0.35D=$12.25
D=35
.
Q=D+3=35+3=38
ANSWER: He has 38 quarters.
To find decimal and percent, we have to simplify the denominator to 100. To do this, we divide both sides by 2:
3/200 = 1.5/100
The decimal would be 0.015, and the percent would be 1.5%
