Answer: 12.5
Step-by-step explanation:
x/10 = 10/8
reduce the fraction with 2
x/10=5/4
simplify the equation using cross-multiplication
4x=50
divide both sides by 4
x=25/2
or
x=12.5
Answer:
y = 2
Step-by-step explanation:
y varies inversely with x setup is:
y = k/x
7 =
(find 'k')
k = 7/1 · 2/3
k = 14/3
use what you know about 'k' and 'x' to solve for 'y'
y = 14/3 ÷ 7/3 (remember to multiply by the reciprocal when dividing fractions)
y = 14/3 · 3/7
y = 2

Answer:
Let the measure of each side of the square be " x " cm.
then ,
area of square = x²
After we folded the square into a rectangle ,
length of rectangle = x
breadth of rectangle = x/2
perimeter of rectangle = 36 cm

hence ,
side of square = 12 cm
therefore ,
area of square = 12 × 12 = 144 cm²
