I believe your answer should be C > -5/4
Answer:
to get you answer you would have to add 1 1/2 and 2 1/4, then your equation would be 60 ÷ 3 3/4 , then whatever your total is, multiply that by 40 and that would be your answer
The circumference of pool is 25.12 feet
<em><u>Solution:</u></em>
Given that round wading pool at the Greenville Community Center has a diameter of 8 feet
Therefore,
Diameter = 8 feet
We know that,
Thus radius is 4 feet
<em><u>The circumference of circle is given by formula:</u></em>
Where, "r" is the radius of circle
Substitute r = 4
Thus circumference of pool is 25.12 feet
3x+5x+1=17
x=2
y=5•2+1
y=1
(x, y)=(2, 11)
3x+2(4x+5)=43
x=3
y=4•3+5
y=17
(x, y)=(3, 17)
