Answer:
36%
Step-by-step explanation:
line up $ and % data like this:
$2.79 represents 100%
$3.79 represents X%
cross multiply
X*2.79 = 3.79*100

Answer:
x = -1/2
Step-by-step explanation:
To solve the equation, we first need to combine like terms:

Simplify further:

Divide by -12 on both sides to get:

To check the solution, plug x back into the original equation and check if we get the correct answer:



Thus, it checks out and our answer is correct.
Answer:
y = 
Step-by-step explanation:
Given
y + v = s ( subtract v from both sides )
y = s - v
Multiply through by 3 to clear the fraction
2y = 3s - 3v ( divide both sides by 2 )
y =
