Step-by-step explanation:
Let the distance be x miles
Time = Distance / speed
Time taken by Mike to go to his friend's house = x / 40 hours
Time taken by him to return = x / 45 hours
Total time = x / 40 + x / 45 = 4 hours
= 9x + 8x = 1440 miles
17x = 1440
= x = 1440 ÷ 7
= x = 84.706
Time taken to return home = 84.706 /45= 1.882 hours .
Therefore , Mike took 1.882 hours to reach home .

9p + 34a = 253 and p + 8= a are the two required equations which will give us the number of phones and accessories sold by Jose
Step-by-step explanation:
Let us denote the number of phones as ‘p’ and number of accessories as ‘a’ So, we can write the following equations from the given data:
Given that levi made $ 253 commission
<u>9p + 4a = 253 (1) </u>
And, Jose sold sold 8 more accessories than phones. So we can frame a equation as follows:
<u>p + 8 = a (2)</u>
These two equations can be used and solved to determine the number of phones and accessories sold.
