Answer:
Step-by-step explanation:
First, we can write:
x
=
1
.
¯¯¯¯
21
Next, we can multiply each side by
100
giving:
100
x
=
121
.
¯¯¯¯
21
Then we can subtract each side of the first equation from each side of the second equation giving:
100
x
−
x
=
121
.
¯¯¯¯
21
−
1
.
¯¯¯¯

We can now solve for
x
as follows:
100
x
−
1
x
=
(
121
+
0
.

x
=

Answer:
Diameter = 7
Radius = 3.5
Step-by-step explanation:
Hi! Ace here.
So, the formula to find circumference is dπ or 2rπ
So to find the diameter, you do the circumference/π
To find the radius, you'd do the circumference/2π
Plug-in those numbers and there you go!
Hope this helps, let me know if you have any questions.
I know this was a very vague explanation so I encourage you to ask any questions. Thank you!
Y - y₁ = m(x - x₁)
y - 3 = 4(22 - 2)
y - 3 = 4(20)
y - 3 = 80
+ 3 + 3
y = 83
