We know that
• It takes 8 hours to travel a certain distance at 36 miles per hour.
,
• At 60 miles per hour, how long would it take?
We solve this problem using the rule of three, or proportions. The image below shows the given relations.
We form the proportion. We have to write down 60 as numerator because it has an inverse relationship, that is, the more speed the least time needed.

<h2>Therefore, it would take 4.8 hours to travel the same distance at 60 miles per hour.</h2>
For this case we have the following equations:
revenue: y = 4x
cost: y = 1 / 2x + 280
We must match both equations:
4x = 1 / 2x + 280
From here, we clear the value of x:
4x-1 / 2x = 280
7 / 2x = 280
x = (2/7) * (280)
x = 80
Answer:
jason needs to sell 80 posters so that the cost and revenue are equal

Answer:
<h2>
y = ¹/₃x + 11 </h2>
Step-by-step explanation:
A line passing through point (x₁, y₁) with the slope of m in point-slope form:
y - y₁ = m(x - x₁)
m = ¹/₃
(-6, 9) x₁ = -6, y₁ = 9
So:
y - 9 = ¹/₃(x - (-6))
y - 9 = ¹/₃(x + 6) ← point-slope form
y - 9 = ¹/₃x + 2 {add 9 to both sides}
y = ¹/₃x + 11 ← slope intercept form
Answer:
I am pretty sure it is 19 blocks because it is 14 blocks before going back home. She needs to walk 3 blocks west and 2 blocks south. 14+3+2=19
