5(x-2)+7=65-4(5x-8)
We move all terms to the left:
5(x-2)+7-(65-4(5x-8))=0
We multiply parentheses
5x-(65-4(5x-8))-10+7=0
We calculate terms in parentheses: -(65-4(5x-8)), so:
65-4(5x-8)
determiningTheFunctionDomain
-4(5x-8)+65
We multiply parentheses
-20x+32+65
We add all the numbers together, and all the variables
-20x+97
Back to the equation:
-(-20x+97)
We add all the numbers together, and all the variables
5x-(-20x+97)-3=0
We get rid of parentheses
5x+20x-97-3=0
We add all the numbers together, and all the variables
25x-100=0
We move all terms containing x to the left, all other terms to the right
25x=100
x=100/25
x=4
Answer:
Diameter of the wheel = 1.2 feet
Step-by-step explanation:
Radius of a wheel = Distance between a point on the circumference and the center of the circle
Diameter of a wheel = 2(radius of the circle)
= 2(0.6)
= 1.2 feet
Therefore, diameter of the wheel is 1.2 feet.

Answer:
4.05 N
Step-by-step explanation:
A newton is kilograms times meters over seconds squared.

Answer: y=175
Step-by-step explanation: y&x
y=kx
(Where k is a constant)
When y=60,x=12...we have
60=12k
Divide both side by 12
12k/12=60/12
k=5
Equation becomes y=5k
Finding y when x=35
y=5(35)
y=175
