Step-by-step explanation:
8 battery =12
20 battery =?(x)
8x=240
x=240÷8
x=30
for 20 battery..it would cost 30

The linear function of a competitor's website
On day 1, both websites have the same subscribers.
This implies that:

Substitute: 



This implies:

On day 34, both websites have the same subscribers.
This implies that:

Substitute: 



This implies:

To calculate the linear function of the competitor, we have:


Calculate slope (m)




The equation is then calculated as:

This gives:

Open bracket

Answer:
x=22
The measure of the angle 2x-10 is 34 degrees.
The measure of the angle 3x-10 is 56 degrees.
Step-by-step explanation:
What you first want to do is add both of the equations up so that they equal 90 which would look like 2x-10+3x-10=90 next add up all like terms to get 5x-20=90. Now you want to add 20 on both sides to get 5x by itself which leaves you with 5x=110. Now you want to isolate x by dividing by 5 on both sides to finally get x=22.
To find the measure of the other two angles you want to simply plug in 22 as the value of x in each so you get 2(22)-10=34 and 3(22)-10=56.
