Set up proportions
8/28=5/21
8*21=168
5*28=140
so no, they are not equivalent
The answer would be 12 and 8/9 inches long if you need simplified its 116/9 inches long
1 foot = 100 yards
2 x 100 = 200
Answer:
39
Work:
(x+5)/2=22
We will reverse this equation.
We will start by moving the 2 through inverse operations.
22x2=44
Now we have the equation
x+5=44
We will subtract 5
44-5=39
x=39
the unknown variable equals 39
