First to find what’s 2x you do 25-11=14, and you know that 7 x 2 =14.
So x= 7.
Answer:
I used the answer the other person gave, but it said it was wrong. Here was the answer I put in the second time.
Step-by-step explanation:
y - y_{1} = m(x-x_{1} )\\
y - (2) = \frac{2}{3} (x - (-1))
y - 2 = \frac{2x}{3} + \frac{2}{3}
y = \frac{2x}{3} + \frac{2}{3} + 2
y = \frac{2x}{3} + \frac{8}{3}[/tex]
y = 2x/3 + 8/3
There's 6 hours and twenty minutes between 8:20 and 2:40, which means you would divide 335 mi by 6.2 hrs. Thats gets you the answer of 54 mph (54.03 to be exact.) Hope that helps!
