Answer: 
is the linear equation.
yes, it is possible.
Step-by-step explanation:
given data:
we were told that she would make $20 for each 5K participant and $45 for each 10K participant.
cost of each 5k participant = $20
cost of each 10k participant = $45.
her target = $9500
<u>solution:</u>
<em>let y represent the </em><em>10k</em><em> </em>
let x represent the 5k participant
the linear equation for this scenarios is
(b.) possibility of having 220 participant in the 5k race.
Answer:
18+30 = 48
6(3+10) = 78
so they're not equal
Step-by-step explanation:
to be equal we have to change 6(3+10) to 6(3+5)
18+30 = 48
6(3+5) = 48
now they're equal
Answer:
9:26, 9/26 or 0.34615384615
Step-by-step explanation:
Ratios are quite simple. It's a division problem. If you've run 17 miles in a 26 mile race, you have 9 miles left. The remaining miles OVER (or divided by) the total miles is your ratio.
Answer:
The 1st graph
Step-by-step explanation:
The quickest and easiest way is to just graph y < x² + 4x + 5. When you do so you should be able to see your answer.
The answer for 17 is 2.7.
The answer for 18 is 6.58.
