Answer:
Step-by-step explanation:
(x + 7)/2 - (x + 4)/2 = (x + 7 - (x + 4)/2 = (x + 7 - x - 4)/2 = 3/2
Answer:
30
Step-by-step explanation:
15% of 200 = 30
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.
