Answer:
Bob drove from home to work at 75 mph. After work the traffic was heavier, and he drove home at 40 mph. His driving time to and from work was 1 hour and 9 minutes. How far does he live from his job?
=================
Avg speed for the round trip = 2*75*40/(75+40) = 6000/115 = 1200/23 mi/hr
RT distance = 1200/23 * 69 minutes * 1 hr/60 mins =
= 60 miles
30 miles each way
Step-by-step explanation:
Product means the result you get after multiplying. So you have to multiply the two numbers. 379*8 = 3032
Answer:
Okay!
Step-by-step explanation:
I have simplified the operation, and I got x^2 + 3.
If you wanted me to evaluate, the answer is still x^2 + 3.
If you wanted me to subtract then the answer is again, x^2 + 3.
Basically the answer is x^2 + 3.
Have a good day!
You can use substitution and solve y-x=2 for y which is y= x+ 2 and plug it into the y of the other equasion and you get x=5 y=7
