Answer:
$29
Step-by-step explanation:
A PS5 costs $500. Subtract 500 from the total cost:
645 - 500 = 145
There are 5 games in total, costing $145 in all. Assuming all of them have the same price, simply divide 145 with 5:
145/5 = 29
Each game costs $29.

Answer:
Step-by-step explanation:
The logarithm function is monotonic with a positive slope everywhere. So, the logs of numbers are in the same order as the numbers themselves. pH is the negative of the logarithm, so the pH values are in the reverse order of the numbers themselves.
Maura's pool has a lower pH, so will have a higher concentration of hydrogen ions.
The log of a ratio is the difference of the logs. Here, the difference of the logs is 7.8 -7.2 = 0.6, so the ratio of H+ concentrations in the two pools is ...
10^0.6 ≈ 4.0
Maura's pool has 4× the H+ concentration of Bill's pool.
Here we have to find lcm of 2 and 3 first
lcm of 2 and 3 is 2*3=6
now we convert both denominator into lcm
combining numerators
=7/6
