Answer:
If Zahara finishes a level in 201 seconds, she earns:
Step-by-step explanation:
To identify the number of points that Zahara obtained when she finished a level in 201 seconds, you must use the given expression:
- -5.5 + 500+ 0.9t + (1 - 1.9t)
Where:
As Zahara took 201 seconds to finish a level, we're gonna replace this value in the equation:
- -5.5 + 500+ 0.9t + (1 - 1.9t)
- -5.5 + 500+ 0.9(<u>201</u>) + (1 - 1.9[<u>201</u>]) (we're not use the unit "seconds", because we don't need it in this calculation)
- -5.5 + 500+ 180.9 + (1 - 381.9)
- -5.5 + 500+ 180.9 - 380.9 (You can organize the numbers is you want)
- 500 + 180.9 - 380.9 - 5.5
- <u>294.5 points</u>
As you can see, <u>Zahara obtains 294.5 points if she finishes the level in 201 seconds</u>.
Answer:
Answer=8
Step-by-step explanation:
Three less than the quotient of 10 and a number increased by 6
Quotient of ten and a number=10/n
(10/n-3)+6
Let n=2
(10/2-3)+6
(5-3)+6
=2+6
=8
The answer is 8
Answer:
its actually 16
Step-by-step explanation:
I don't think you actually have to solve this. I think you just have to write out the equations. It would be:
Mark: 4s + 3c = 26
Brian: 5s + 2c = 29
Divide each side by ( I R ) .
