Answer: 53.659 seconds
Step-by-step explanation:
Given: Vega swam her leg of the race in 27.98 seconds.
Janice swam her leg of the relay race in 25.679 seconds.
Then , their combined time for their part of the relay = (Time taken by Vega) + (Time taken by Janice)
= 27.98 seconds +25.679 seconds
= (27.98+25.679) seconds
= 53.659 seconds
Hence, their combined time for their part of the relay = 53.659 seconds
Answer:
d = 12.21
Step-by-step explanation:
1) Subtract 4 from both sides.
d = 16.21 - 4
2) Simplify 16.21 - 4 to 12.21.
d = 12.21
Check the answer!
⇒ d + 4 = 16.21
1. Let d = 12.21.
⇒ 12.21 + 4 = 16.21
2. Simplify 12.21 + 4 to 16.21
16.21 = 16.21
Done!
Thanks,
