Answer:
8 cm
Step-by-step explanation:
100% sure
A)your equation for t-mobile would be
y=20x+100
Topar equation
y=30x
B) you’d set the two equation equal to each other
20x+100=30x
giving you the answer x=10
C) when x>13
D) when x<14
i’m a bit iffy on the last two but that’s the conclusion i came to
Hello,
Answer B
An exterior angle of a circle has like measure the half of difference of the arcs.
mes S=(85°-25°)/2=60°/2=30°
For this case we have the following equation:
![s = \frac {2x + t} {r}](https://tex.z-dn.net/?f=s%20%3D%20%5Cfrac%20%7B2x%20%2B%20t%7D%20%7Br%7D)
We must clear the value of the variable "x" as a function of r, s and t:
If we multiply by "r" on both sides of the equation we have:
![rs =2x + t](https://tex.z-dn.net/?f=rs%20%3D2x%20%2B%20t)
If we subtract "t" on both sides of the equation we have:
![rs-t = 2x](https://tex.z-dn.net/?f=rs-t%20%3D%202x)
If we divide by "2" on both sides of the equation we have:
![x = \frac {rs-t} {2}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%20%7Brs-t%7D%20%7B2%7D)
Thus, the value of the variable "x" is:
![x = \frac {rs-t} {2}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%20%7Brs-t%7D%20%7B2%7D)
Answer:
![x = \frac {rs-t} {2}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%20%7Brs-t%7D%20%7B2%7D)
Answer:
it would be 36-45 and 56-64
