The expression for the circumference of the circle is 2πr, where π is approximately 3.14 and the r is the radius of the circle, 1.4 inches. So the circumference of the circle is

. So the circumference of the circle is 8.792 inches.
X intercept is when y=0
6x-2=0
x=1/3
x intercept is (1/3,0)

Answer:
To solve this we need to form 2 equations with only 2 variables.
x+4y-5z=-7
2x+y+5z=8
3x+5y=1
15x+10y+15z=35
6x+3y+15z=24
9x+7y=11
Now we need to use these to find x and y
9x+15y=3
9x+7y=11
8y=-8
y=-1
Therefore:
x=2
From this we can find that:
2(2)-1+5z=8
Therefore z=1
The answer is x=2, y=-1, z=1
Answer:
x = -25
Step-by-step explanation:
25 = -7(x + 5) + 5x
25 = -7x - 25 + 5x
5x - 7x - 25 = 25
5x - 7x - 25 + 25 = 25 + 25
5x - 7x = 50
-2x = 50
-2x/-2 = 50/-2
x = -25
