7r-5r+8=9r+8-r translate to an equation, then solve

pshichka [43]

Answer:

r=0

Step-by-step explanation:

7r-5r+8=9r+8-r

This is already an equation

Combine like terms

2r+8 = 8r+8

Subtract 2r from each side

2r-2r +8 = 8r-2r +8

8 =6r+8

Subtract 8 from each side

8-8 = 6r+8-8

0 = 6r

Divide by 6

0/6 = 6r/6

0 =r

After each charging, a battery is able to hold only 97% of the charge from the previous charging. The battery was used for 18 ho

Cerrena [4.2K]

Answer:

The total nuber of hours that the battery can be used over its lifetime is 600.

Step-by-step explanation:

We use an infinite geometric series to solve this question.

The sum of all values of an infinite geometric series is given by the following equation:

$S = \frac{a_{1}}{1 - r}$

In which $a_{1}$ is the first term and r is the common ratio.

After each charging, a battery is able to hold only 97% of the charge from the previous charging.

This means that $r = 0.97$

The battery was used for 18 hours on its first charge before it had to be recharged.

This means that $a_{1} = 18$

What is the total number of hours the battery can be used over its lifetime?

$S = \frac{18}{1 - 0.97} = 600$

The total nuber of hours that the battery can be used over its lifetime is 600.
