C is the answer for the pic
First, you would subtract 4.25 from 6.25 and that would be equal to 2.
Then, you would take 2.25z and subtract it from 3.5z and it would equal 1.25z.
Next, you would separate the z by dividing 1.25 on both sides. Z=1.6
Answer: B
There is only one solution.
Answer:
Step-by-step explanation:
For pi i use the estimate 3.14
First find the radius of the sphere using the formula circumference= pi * diameter 
then divide both sides of the equation by d to get the diameter, which is about 86.94.
To get the radius, divide the diameter by 2, which equals 43.47.
Use the formula 
to get the surface area, which is, rounded to the nearest number, is 23,734 feet
To find out the number of hours per week, we have to divide 24 by 4.
24 ÷ 4 = 6
Monique volunteered 6 hours per week at the animal shelter.
Hope this helps!
We have system:
y=2x+1
y=2x^2+1
To find which ordered pair is solution to this system we need to solve system for x and y.
Left sides are same so the right sides must be same too.
2x+1=2x^2+1
2x-2x^2+1-1=0
2x-2x^2=0
2x(1-x)=0
x1=0
x2=1
y1=2*0+1=1
y2=2*1+1=3
The solution are pairs (0,1) and (1,3).
