Answer:
Step-by-step explanation:
Consecutive interior angles between parallel lines are supplementary.
Let's start with x.
(8x +40)° +(6x)° = 180°
14x +40 = 180 . . . . . . . . . divide by °, collect terms
14x = 140 . . . . . . . . . subtract 40
x = 10 . . . . . . . . divide by 14
__
We can use the same approach for y:
(7y)° +(3y -10)° = 180°
10y = 190 . . . . . . . . . . . divide by °, add 10, collect terms
y = 19 . . . . . . . . . . . divide by 10
If the work required to stretch a spring 2 ft beyond its natural length is 9 ft-lb,then the work that is needed to stretch it 18 inches beyond its natural length is 81 ft.lb.
Given that work required to stretch a spring 2 ft beyond its natural length is 9 ft-lb.
We are required to find the work that is needed to stretch 18 inches beyond its natural length.
Multiplication is basically finding out the product of two or more numbers.
Work required to stretch the spring 2 feet beyond its natural length=9 ft. lb.
So, to find the work that is required to stretch the spring 18 feet beyond its natural length, we have to multiply 9 with 9 which will give us 81. So the work required is 81 ft.lb.
Hence if the work required to stretch a spring 2 ft beyond its natural length is 9 ft-lb,then the work that is needed to stretch it 18 inches beyond its natural length is 81 ft.-lb.
