Answer:
f(4)=14
Step-by-step explanation:
f(x)=5x-6
f(4)=5(4)-6
f(4)=20-6
f(4)=14
I'm not sure if that's what you mean, but the difference between 6010 and 5060 is 950, so to find a number in a halfway between them I divided 950 by 2 (which is 475) and added it to 5060 (or substracted from 6010 - it's the same). Next I added the same number (475) to 6010. So finally it would like like this:
6,485 ; 6,010 ; 5,535 ; 5,060
Ummmmm lets see.... 1? Because then 3 times 1 is 3 + 3 = 9 so that's the only answer that works
Answer:
72 runners
Step-by-step explanation:
Total runners = 360
20% of the total runners are in the 35-39 age bracket.
<em>We need to find number of runner in this age bracket.</em>
<em>Which tells us that this number is simply 20% of the total, or 20% of 360.</em>

How to find percentage of number?
We convert percentage to decimal and then multiply it with the other number.
Converting percentage to decimal requires us to divide by 100. So:
20% = 20/100 = 0.2
Now,
0.2 * 360 = 72
Hence,
72 runners are in the 35-39 age bracket
In slope intercept form it would be y=2x+8
