Answer:
x+y=5a
5a is added to b which is the sum of x and y multiplied by 3. That is, b=x+y×3=5a×3=15a
Since, 5a is added to b= 5a+15a=20a,
Answer:
Given:
(i) Wendy reduced her daily commute time by 75% by learning how to fly.
(ii) Previously, it took her 'm' minutes to commute.
To find:
(i) Wendy's commute time in minutes after she learned how to fly.
Solution:
Given that earlier it took Wendy 'm' minutes to commute.
After learning how to to fly, the commute time reduced by 75%.
So, time taken now = (100-75)% of previous time
= 25% of 'm' minutes
= \frac{25m}{100}
100
25m
= \frac{m}{4}
4
m
So, the time taken by Wendy now is \frac{m}{4}
4
