Given:
Melinda walked to the mall at 4 miles per hour and then rode back home in a bus at 24 miles per hour.
Total traveling time was 14 hours.
To find:
The distance between Melinda's house and mall.
Solution:
Formula used:
Let x miles be the distance between Melinda's house and mall.
Melinda walked to the mall at 4 miles per hour. So, the time taken by Melinda is hours.
Speed of bus is 24 miles per hour. So, the time taken by bus is hours.
Total traveling time was 14 hours.
Divide both sides by 7.
Therefore, the mall is 48 miles far from Melinda's house.
Answer:
Correct option: C -> 2
Step-by-step explanation:
The first equation is:
And the second equation is:
From the second equation, we have:
Using this value of y in the first equation, we have:
Calculating the discriminant Delta, we have:
We have , so we have two real values for x, therefore we have two solutions for this system.
Correct option: C.
(If the system of equation is actually:
We would have:
We also have , so we have two solutions for this system.
Correct option: C.)
Answer:
30%
Step-by-step explanation:
if it is six sides and the number only goes from one to six then you have to count how many even numbers are in between 1 and 6. That would be 2, 4, and 6. that is 3 numbers. And 3 over 10 is 3/10 which changes from a fraction into a percent and the percent is 30%. I hope you understand this sorry if you can't. Love ya bye.
