Answer:
It will take 8 days to complete the trip.
Step-by-step explanation:
3104 miles total
388 miles a day
3104/388 = 8
The value of m will be (mV₂ + Mv₂)/V₁ so Brenna's equation is absolutely correct.
<h3>What is the equation?</h3>
A formula known as an equation uses the same sign to denote the equality of two expressions.
An equation can be defined in numerous ways. Algebraically speaking, an equation is a statement that shows the equality of two mathematical expressions.
Given,
mv₁ = (m + M)v₂
By multiplication on the right-hand side
mv₁ = mv₂ + Mv₂
Divide v₁ on both side
mv₁/v₁ = ( mv₂ + Mv₂)/v₁
m = (mV₂ + Mv₂)/V₁
Hence Brenna's solution is correct for the equation.

Answer:
I believe it's A
Step-by-step explanation:
I'm not so sure because I did this a while back
Hi there! :)
Answer:
(75x - 67y) - (47x + 15y)
Distribute the '-' sign with the terms inside of the parenthesis:
75x - 67y - (47x - (15y))
75x - 67y - 47x - 15y
Combine like terms:
28x - 82y
Distribute out the greatest common factor:
2(14x - 41y)
Statements 2 and 3 contradict as if both items cost less than $15, the most money spent on either individually would be $14.99, and together would add up to $29.98, and that is at their maximum price, therefor Val couldn’t have spent $34 on both items together.
