10x+20y=540
x+y=34
y=34-x
Plug in (34-x) for y:
10x+20(34-x)=540
10x+680-20x=540
-10x=-140
10x=140
x=14

Answer:
The answer to your question is Area = 9 3/8
Step-by-step explanation:
Data
length = 3 3/4 cm
width = 2 1/2 cm
Process
1.- Write the equation of the Area of a rectangle
Area = length x width
2.- Convert the values to improper fractions
3 3/4 = (12 + 3)/ 4 = 15/4
2 1/2 = (4 + 1) / 2 = 5/2
3.- Substitution
Area = (15/4)(5/2)
4.- Simplification
Area = 75/8
5.- Convert to a mixed fraction
9
8 75
3
6.- Result
Area = 9 3/8
X = 360 - (158 + 148 + 32)
x = 360 - 338
x = 22
