54 = 2(4x-3) + 2(x)
54 = 8x-6 + 2x
60 = 10x
6 = x
so two sides are 6 meters, and the other 2 sides are 21 meters
the length of each equal side is 10 ft
the length of the third side is 2 ft
let x be the length of the third side the equal sides are 4x + 2
given perimeter == 22, then
x + 4x + 2 + 4x + 2 = 22
9x + 4 = 22 ( subtract 4 from both sides )
9x = 18 ( divide both sides by 9 )
x = 2 and 4x + 2= 10
Answer:
x = 9.6 in
Step-by-step explanation:
The scale factor is 8:10 (difference in length.) This is simplified down to 4:5.
Method 1 (easier):
4/5 × 12 = 9.6 in.
Method 2 (harder but more comprehensive):
<em>cross-multiply</em>
<em></em>
18/60 which is equal to 3/10
So you just need to put it into proportions which is blue to total. The total is 60 and there is 18 blue. Then you only need to simplify.
