Answer:
.
Step-by-step explanation:
to give b from both equation the same value
a:b:c = 8:6:9
a = 8
b = 6
c = 9
8/2(2+2)=X
8/2(4)=X
4(4)=X
16=X
Your answer would be X=16
Answer:
D
Step-by-step explanation:
Let's call the width of the yard x and the length x + 3½. Since we know that perimeter = 2 * (width + length) and that the perimeter must be 26 we can write:
2 * (x + x + 3½) = 26
x + x + 3½ = 13
2x + 3½ = 13
2x = 9½
x = 4
If a:b=c:d then a/b=c/d and ad=bc
so
if 16:14=64:60 then 16/14=64/60 and (16)(60)=(14)(64)
(16)(60)=960
(14)(64)=896
960≠896
not equivilent
the easiest way is to simplify them
16/14=8/7
64/60=32/30=16/15
not equal
not equivilent
