5 is the correct answer kind sir
You have to use a system. the first would be x + y = 12 since she has 12 coins. the other equation would be 0.05x + 0.1y = 0.95 (an easier way is 5x + 10y = 95 if you clear it). now you just solve using substitution or elimination.
Answer:
X = 1/2
Step-by-step explanation:
The question seems like (6*4x² = 3*4x)
This is a simple algebraic equation
First of all, multiply the coefficient of x by the number on each side.
6*4x² = 3*4x
24x² = 12x
Divide both sides by 12
2x² = x
Divide both sides by x
2x = 1
Solve for x
x = 1/2
