Answer:
C = 56.6
Step-by-step explanation:
Circumference Formula: C = 2πr
Simply plug in <em>r</em> into your formula
C = 2π(9)
C = 18π or 56.556
HOW TO SOLVE:
1) use x as a variable
2) the starting equation is:
4x + 3x + 5x = 18
3) add all the like terms on the left side of the equation:
12x = 18
4) Divide by 12 on both sides:
x=1.5
5) Find the lengths of the sides:
- 4x = 4(1.5) = 6
- 3x = 3(1.5) = 4.5
- 5x = 5(1.5) = 7.5
SO, the lengths of the sides of this triangle are: 6, 4.5, and 7.5

Step-by-step explanation:
<u>Solving Equations</u>
We have the expression:

And it's required to make y the subject.
It can be done by isolating y on the left side of the equation and the rest of the expression on the right side.
The first step is removing the denominator by multiplying both sides by y-3:

Simplifying the right side:

Remove the parentheses:

Move the y's to the left side and the rest of the expression to the right side:

Factor out y:

Divide by x-1:

Answer:
0.6
Step-by-step explanation:
the car moves at a speed of 3/5*65 miles per hour
that is 39 miles per hour
but this has nothing to do with the question as the only fraction is 3/5
