Answer:
l = 10 m
w = 5 m
Steps:
Set equations:
l = 2w
30 = 2l + 2w
Substitute 2w with l in second equation to find l:
30 = 2l + 2w
30 = 2l + l
10 = l
Plug in 10 into first equation to find w:
l = 2w
10 = 2w
5 = w
-21
27 divided by 9 = 3
3 X -7= -21
Answer:
15.68
Step-by-step explanation:
22/15=23/x
cross product
15*23=22*x
345=22x
x=345/22
x=15.68
6 7/8 -> 55/8 /5= 11/8*6= 66/8 /2 = 33/4
Answer:
x=1
Step-by-step explanation:
when both are graphed the lines intersect at (1,0) or x=1
