Answer:
In a square, all sides are equal. This means that each side is 3x inches in length.
The sum of the sides is 48 inches
There are 4 sides in a square.
3x + 3x + 3x + 3x = 48
<em>12x = 48</em> ----> is the equation
This means that x = 4
Each side is 3x inches in length, hence each side is also 3(4) which is 12 inches or 1 feet.
Step-by-step explanation:
Bananas cost: $0.25
Apples cost: $0.30
4b+5a=2.50
10b+3a=3.40
You multiply the equations by the variables so they can cancel out. For example the first one by 3 and the second by 5 so you have
12b+15a=7.50
50b+15a=17
Subtract them and end up with
-38b=-9.5
solve: b=0.25, substitute b in any equation and get a=0.30
