Answer: x = 8, y = 2, coordinates (8,2)
Step-by-step explanation:
2x = 4y + 8 (divide by 2 to get value of x)
x = 2y + 4
(now substitute x into the second equation to find value of y)
2y + 4 - 2y = 4
2y - 2y = 4 - 4 (divide by 2 to get value of y)
y - y = 2 - 2
y = 2
Now plug in value of "y" to get value of "x".
x - 2(2) = 4
x - 4 = 4
x = 8
Coordinates (8,2)
90.89, 90.9, 98.9, .09
67.33, 67.03, .87, .09
The circumference of a circle is 2(3.14)r, and if 8.5 * 2 is 17, the answer will be 17*3.14.
An estimate is 51, and the actual answer is 53.38.
