Assume that pi is approx. 3.14. Then 86.92 = approx. 27 2/3 times pi, or
86.92 is approx. equal to 83pi/3.
8x+8y=2
-) 8x+5y=1
——————
3y=1
y=1/3
8x+8(1/3)=2
24x+8=6
24x=-2
x=-1/12
(-1/12,1/3)
To find the answer just divide the length of a flower garden by the length of a brick:
11.25 / 0.25 = 45 (that's how many bricks are needed to be put).
There's nothing to round, but you can write it as a decimal to the hundredth place as 45.00.
Answer:
x=8 y=4
Step-by-step explanation:
x=12-y
12-y-y=4
-2y=-8
y=4
x=12-y
x=12-4
x=8
