Hello!

To find the circumference of a circle, you multiply the diameter by pi. Let's do so below.

210\pi \approx 659.73

Therefore, our circumference is about 659.73 cm.

I hope this helps!

Add using a number line 5/6+(-1 1/6) drag and drop word sum to the correct value on the number line
wel
<span>To find this answer, the second value needs to be converted into an improper fraction. (-1 1/6) becomes (-7/6) when properly converted. Then, 5/6 + (-7/6) becomes the same as (5/6) - (7/6). Since both have common denominators, the numerators can simply be subtracted: (5-7) = -2. This leaves a sum of (-2/6), which can be reduced to (-1/3).</span>

Can someone help me answer these two questions? I wanna know what's right and wrong. Please correct me if Necessary

Remember that the general equation of a line is y=mx+b, where:
m is the slope, and b is the y-intercept; so to find the y-intercept, solve for y and identify b.
Now, to find the x-intercept, just replace y in your line equation with 0, and solve for x
Lets apply those procedures to our two questions:

1. - y-intercept:
-10x+5y=40
5y=10x+40
y= \frac{10x+40}{5}
y=2x+8
Notice that now we have our line equation in the form y=mx+b with m=2 and b=8; sine b is the y-intercept, we can conclude that the y-intercept of our equation is 8.

x-intercept:
First, lets replace y with 0:
0=2x+8
And then, we can solve for x to find our x-intercept:
2x=-8
x= \frac{-8}{2}
x=-4
We can conclude that our x-intercept is -4; thus the correct answer in your list is the fourth one: x-intercept is -4; y-intercept is 8.

2. y-intercept:
5x+4y=80
4y=-5x+80
y= \frac{-5x+80}{4}
y=- \frac{5}{4} x+20
We can conclude that our y-intercept is 20.

x-intercept:
0=- \frac{5}{4} x+20
- \frac{5}{4} x=-20
x=( \frac{4}{5} )(20)
x=16
We can conclude that our x-intercept is 16; thus the correct answer in your list is, once again, the fourth one: x-intercept is 16; y-intercept is 20.
