3 km = 3000m
600m:3000m divide by 10
60:300 divide by 10
6:30 divide by 3
2:10 divide 2
*1:5* (simplest form)
Answer:
The correct answer is D. 3x² - x + 3
Step-by-step explanation:
4x² - x + 6 - (x² + 3)
= 4x² - x² - x + 6 - 3
= 3x² - x + 3
To solve this problem we can make a proportion.
6 5
-- = ---
10 x
to solve this proportion we can cross multiply and divide.
5 times 10 is 50. divided by 6 is 8.3
it will take her 8.3 minutes to run 5 laps
The first step to solving this problem is to plug in 6 where you see a in the expression
-6² - 6 (-6) + 4
the first step to solving this is to evaluate the power
-36 - 6x (-6) + 4
next you will multiply the numbers
-36 + 36 + 4
finally,, eliminate the opposite of the expression to find your answer
4
this means that the correct answer to your question is 4.
