Answer:
28 < x < 114
Step-by-step explanation:
- x cannot be larger than or even equal to 71 + 43 = 114. So it must be less than 114.
- But there are limits on the other end as well. 43 +x > 71, otherwise you won't have a triangle. so you have to solve that inequality as well
- 43 + x > 71 Subtract 43 from both sides.
- 43-43 + x > 71 - 43
- x > 28
- To put this in the form of the answer you need it looks like this.
- 28 < x < 114
There are a couple ways to determine the number of minutes it will take Charlie to run 9 laps, but the easist would be to find out what is happening to each number of laps in order to get the number of minutes. In each case, the number of laps is being multiplied by 5 to get the number of minutes.
9x5=45 minutes.
He is running each lap in 5 minutes.
Answer:
1) 6 (9x - 5)
2) 4 (1 + 6)
Step-by-step explanation:
<u>1.</u>
54x - 30
The greatest common factor is 6, hence take out 6
6 (9x - 5)
<u>2.</u>
4 + 24
The greatest common factor is 4, take out 4
4 (1 + 6)
*I am not simplifying this because as per what is given, I am unsure if one of these numbers is actually a coefficient.
Answer:
r = 7
Step-by-step explanation:
14 divided by 2 is 7
42 divided by 6 is 7
77 divided by 11 is 7
So the constant of proportionality is 7
r = 7
