Answer:
r = 13
Step-by-step explanation:
these angles are vertical and are congruent
8r + 6 = 9r - 7
6 = r - 7
13 = r
Answer:
x= -2/3 y+4
Step-by-step explanation:
Let's solve for x.
3x+2y=12
Step 1: Add -2y to both sides.
3x+2y+−2y=12+−2y
3x=−2y+12
Step 2: Divide both sides by 3.
3x
3
=
−2y+12

Answer:
4π ≈ 12.5663706144
Step-by-step explanation:
The circumference of a circle is 2πr, or 2*pi*radius
Suppose the circle has a diameter of 4 inches. A diameter is 2x the radius, of which we are looking for, therefore:
4÷2=<u>2 inches</u> (radius length)
Now that we have the radius, let us <u>substitute</u> to find the circumference:
2πr=
2π2=
4π≈
<u>12.5663706144</u>
<u></u>

Answer:
$58.50
Step-by-step explanation:
It is given that the student council pays
For per french fry = $0.85
For per soda fry = $1.20
Discount on the combo of fries and soda = $0.75
Total revenue for one combo = $0.85 + $1.20 - $0.75 = $1.30
Since the total revenue for one combo is $1.30, therefore the total revenue for 45 combo is
Total revenue for 45 combo = 45 × $1.30 = $58.50
Therefore, they will make $58.50 if they sell 45 combos.
