Hope this helps! :)
Answer:
Step-by-step explanation:
A.)
Let the equal number of hours be represented by variable h;
The two equations will be as follows;
Jack; 40 +30h
Mark; 50 +25h
Next, equate them;
40 + 30h= 50 + 25h
30h - 25h = 50 - 40
5h = 10
h =10/5
h = 2
Therefore, they charge the same amount at 2 hrs.
B.) The amount charged;
Replace the variable H in any of the two equations above with 2 to solve for the amount.
Equation 40+30h = 40 + (30*2)
=40 + 60
= $100

Equivalent / Equal
Step-by-step explanation:
Answer:
6 hours
Step-by-step explanation:
We have that the speed in this case would be given per project / hour
Which means, that the speed of Jernai would be:
1/4 project / hour and also that the speed of the two meetings would be 1 / 2.4 project / hour, we know that this result must give more the sum of daniela's speed, therefore:
1/4 + 1 / x = 1 / 2.4
where x is the time in hours that daniela takes:
1 / x = 1 / 2.4 - 1/4
1 / x = 0.1666
x = 1 / 0.1666
x = 6
Which means that Daniela takes 6 hours to do her project if she does it alone
Answer:
392
Step-by-step explanation:
28 times 14
or you can take 1 divided by 28 and you should get 0.03571428571428571 then take 14 times 0.3571428571428571 and you should get 39.2 and then just move your decimal place over to the right one place. and your answer will be 392 miles
