Answer:
let this happens after t hours
so
80t + 60t = 392
140 t = 392
t = 392/140
=2.8 hours

By the way, I'm doing the same exam for Geometry as well. There's a lot of proof questions on there which I'm not good at doing for the reasoning part. If you finish the exam before I do, maybe you can message me what the answers are for some of the questions on there so I know if my answers for the questions are incorrect or not.
Besides that, hope the answer above is correct for you.

Answer:
The equation is 
Andrea will donate $200 for business scholarships and $600 for liberal arts scholarships.
Step-by-step explanation:
Given
Represent Liberal Arts with L and Business with B
From the question, we have that:
and
Required
Determine how much she donates for each
The total L + B is 800
i.e.
Substitute 3 * B for L
Solve for B
Recall that :
We know that ideally a Quaker oatmeal container should have 32 oz. oatmeal.
We also know that a difference of 0.5 oz. is acceptable, otherwise the container is rejected.
Let the amount of oatmeal actually present in the container be Q
32 - 0.5 < Q < 32 + 0.5
⇒ 31.5 < Q < 32.5
Hence, the equation that represents the highest and lightest acceptable weights is 31.5 < Q < 32.5.
Answer:
<h2>
y + 2 = ³/₄(x + 8)</h2>
Step-by-step explanation:
The point-slope form of the equation that describes the line with a slope of <em>m</em> and containing the point (x₀, y₀) is: y - y₀ = m(x - x₀)
m = ³/₄
(-8, -2) ⇒ x₀ = -8, y₀ = -2
Therefore:
y - (-2) = ³/₄(x - (-8))
y + 2 = ³/₄(x + 8)
