Answer:
You want to buy long pieces of paper at Dollar Tree for 66 cents. You have $12. How many long pieces of paper can you buy
Step-by-step explanation:
5x - 3y + 1 = 16 ⇒ 10x - 6y + 2 = 16
2x + 5y + 0 = -6 ⇒ <u>10x + 25y + 0 = -6</u>
31y + 2 = 10
<u> -2 -2</u>
<u>31y</u> = <u>8</u>
31 31
y = 8/31
5x - 3(8/31) + 1 = 16
5x - 24/31 + 1 = 16
5x + 7/31 = 16
<u> -7/31 -7/31</u>
<u>5x</u> = <u>10 24/31</u>
5 5
x = 2 24/155
(x, y) = (2 24/155, 8/31)
<span>y = x + 3 / 12

Answer:
=75.36 m^2
Step-by-step explanation:
The formula for circumference, or the distance around the circle, is given by
C = pi*d = 2pi*r
Using the radius is 12 meters
C= 2*pi*r
= 2*pi*12
= 24 pi
We are given pi = 3.14
= 24 * 3.14
=75.36 m^2
