Answer:
1) 2 hours
2) 96 miles
Step-by-step explanation:
1) Eliot and William went hiking. They went at the same speed. Let x mph be their speed.
<u>Elliot:</u>
Distance = 8 miles
Speed = x mph
Time 
hours
<u>William:</u>
Distance = 12 miles
Speed = x mph
Time 
hours
It took Eliot 
less than William, then
![\dfrac{8}{x}+\dfrac{2}{3}=\dfrac{12}{x}\\ \\\dfrac{2}{3}=\dfrac{12}{x}-\dfrac{8}{x}\\ \\\dfrac{2}{3}=\dfrac{4}{x}\\ \\2x=3\cdot 4\ \ [\text{Cross multiply}]\\ \\2x=12\\ \\x=6\ mph](https://tex.z-dn.net/?f=%5Cdfrac%7B8%7D%7Bx%7D%2B%5Cdfrac%7B2%7D%7B3%7D%3D%5Cdfrac%7B12%7D%7Bx%7D%5C%5C%20%5C%5C%5Cdfrac%7B2%7D%7B3%7D%3D%5Cdfrac%7B12%7D%7Bx%7D-%5Cdfrac%7B8%7D%7Bx%7D%5C%5C%20%5C%5C%5Cdfrac%7B2%7D%7B3%7D%3D%5Cdfrac%7B4%7D%7Bx%7D%5C%5C%20%5C%5C2x%3D3%5Ccdot%204%5C%20%5C%20%5B%5Ctext%7BCross%20multiply%7D%5D%5C%5C%20%5C%5C2x%3D12%5C%5C%20%5C%5Cx%3D6%5C%20mph)
So, William's hike was
hours long.
2) <u>Initially:</u>
Distance = 120 miles
Speed = 55 mph
Time 
hours
<u>Final:</u>
Speed = 44 mph
Time 
hours
Distance 
Answer:
488
Step-by-step explanation:
= 0 - replace x = -9 => 6 x (-9)^2 + 2 = 488
We have a system of equations here:
Let 'a' = adult tickets and 'c' = children's tickets
5.80c + 9.00a = 1056.20
We also know that the total number of tickets (adults and children) was 149:
a + c = 149
We need only solve the system.
Shouldn’t there show the diagram - unless i have to draw one , unless there’s 1 side with the length of 12
