Start by turning the mixed number to an improper fraction by multiplying the 3 and 4 to get 12 and then add on 3 to that to get 15/4.
So not you have -2/3 ÷ 15/4. Do the reciprocal of 15/4 to get 4/15 and change the ÷ to a x (that's multiplication sign. After that multiply. -2/3 x 4/15 and the answer would be -8/45 :)
Answer:
900.4%
Step-by-step explanation:
Move the decimal point two places to the right.
Length (L): 2w + 3
width (w): w
Perimeter (P) = 2L + 2w
60 = 2(2w + 3) + 2(w)
60 = 4w + 6 + 2w
60 = 6w + 6
54 = 6w
9 = w
Length (L): 2w + 3 = 2(9) + 3 = 18 + 3 = 21
Answer: width = 9 feet, length = 21 feet
Subtract 6.22 from 20.25
20.25
06.22
---------
14.03
Your change is $14.03
First, you do -5 plus 5 and whatever you do on one you you must do on the other so you add -1 +5 which gives you 4. Then you multiply by 4 on both sides so you can get a by itself. So 4 times 4 is 16.
A= 16
