Answer:
to get x by itself so divide 5 by 2 and then add 7 to the other side
Step-by-step explanation:
2x-7=5
x-7=2.5
x=2.5+7
x=9.5
Answer:
When y=32, x=16.5
Step-by-step explanation:
Find x when y = 32, given that x varies inversely as y, and x = 132 when y = 4.
We are given:
x varies inversely with y
We can write it as: 
We have x = 132, when y=4
We can find value of k by using these values
We need to find x when y=32
So, when y=32, x=16.5
No, it’ll be just 49 not negative 49. Because you times they by it’s self and the negatives cancel eachother !
The formula for circumference is 2 x Pi x R or Pi x D. The diameter is twice the radius, always. With the information I have provided, we can solve this.
Our radius is 7.
Multiply the radius by 2 to get the diameter.
7 x 2 = 14. Since you have requested for the answer to be in terms of Pi, I will assume you mean "14Pi" as your final answer. If not, I will multiply 14 by Pi to get our circumference.
3.14 x 14 = 43.96 cm^2
Your answers are:
14(Pi) cm^2
or (if completely done)
43.96 cm^2
The Area of a circle is PiR^2, or Pi x R x R. Our radius is 7, so to solve this, we need to: Multiply 7 by 7 and then multiply that product by 3.14. 7 x 7 = 49. 49 x 3.14 = 153.86 cm^2 Your area is 153.86 cm^2. Your circumference is 43.96cm^2. I hope this helps!
