Answer:
x = 
and y = 
Step-by-step explanation:
Known that he sum of angles on a straight line is 
. From the diagram;
2y + x + y =
x + 3y = ................ 1
Also,
2x + x + 2y =
3x + 2y = .............. 2
Using the elimination method, multiply equation 1 by 3 and equation 2 by 1
3x + 9y = 540 ............ 3
3x + 2y = ............. 4
7y = 360
y = 
y =
substitute the value of y in equation 1,
x + 3y =
x + 3(51.4) =
x + 154.2 =
x = - 154.2
x =
Thus, x = and y =
The perimeter of a polygon is equal to the sum of all its sides. In a rectangle with dimensions length, x and width, y is calculated through the equation,
P = 2x + 2y
If width is y, then length is equal to 3y - 8. Substituting these to the equaiton,
P = 2(3y - 8) + 2y
Simplifying,
24 = 6y - 16 + 2y
24 = 8y - 16
The value of y from the equation is 5.
x = 3y - 8 = 3(5) - 8 = 7
Answers:
x = 7 feet
y = 5 feet
Answer:
250 : 500 : 750 : 1000
Step-by-step explanation:
2500 ÷ 1+2+3+4
2500 ÷ 10
250
Therefore the answer is,
1 : 2 : 3 : 4
250 : 500 : 750 : 1000
