Answer:4 100/477
Step-by-step explanation:You need to divide it.And first you change the mixed numbers 27 8/9 and 6 5/8 to improper fraction .27 8/9 as a improper fraction is 251/
9
. 6 5/8 as a improper fraction is 53/
8
.ANd now you divide 251/
9 by 53/
8.In order to divide fractions you need to do KCF which stand for Keep ,change,flip .SO you have 251/
9 divide 53/
8 ,now you KEEP 251/9 ,Change the division sign to multiplication ,and flip 53/8 to 8/53.And now you multiply 251/9 by 8/53 which gives you 2008/
477.Lastly you change 2008/
477 which is a improper fraction to a mixed number which is 4 100/477.
Answer:
Length: 30m
Width: 12m
Step-by-step explanation:
Length: 2x+6 meters Width: x meters
2(2x+6) meters + 2(x) meters
4X+12 +2x = 84 meters
6x+12 = 84 meters
6x = 72 meters
x = 12 meters
3x-2y= -12
y=4x+1
3x-2(4x+1)= -12
3x-8x-2= -12
-5x=-12+2
-5x=-10
x= -10/-5
x=2
y=4x+1
y=4•2+1
y=8+1
y=9
(x,y) = (2,9)
