At x=6
0=2x-12
12=2x
12/2=6
X=6 at y=0
The books are $16 each. To figure this problem out you have to start with the facts: Benny has $124, he buys seven books, then ends up with $12 left. So first subtract 12 from 124. That equals 112. Next divide 112 by 7, when you do that is comes out to the answer of 16! So $16 is the answer.
1 1/3 is simplified to 4/3
multiply 4/3 * 2/3 =8/9
Answer:
12.6
Step-by-step explanation:
We can start by finding the area of the rectangle
13x4=52
Now the semicircles, the diameter of the circle is 4, so the radius is 2 to find the area we do
pi x 2=6.3
6.28^2=39.4
since there are two circles we can just add them together instead of dividing the answer above by 2, now we can subtract this from 52
52-39.4=12.6
