-3n+48=0
-3n=-48
-3n/-3 & -48/-3
n=16
To solve this problem, I would transfer this word problem into an equation with variables.
let the variable m stand for the amount of movies andrew rents.
5.00+1.25m=16.25
Now that we have our equation, we can just solve it like any other equation.
To do this, first, we would subtract 5.00 from both sides, resulting in the equation
1.25m=11.25
Next, we would divide both sides by 1.25, resulting in your final answer
m=9.
This means that Andrew rented 9 movies if his total was 16.25
To determine what percentage of 642 the number 321 is, we can follow the equation below.
(Smaller Number / Bigger Number)*100
We can plug the numbers into the equation to get our answer.
(321/642)*100 = 0.5 *(100) = 50%
So 321 is 50% of 642
Answer:
x = -6
Step-by-step explanation:
Simplifying
5x + 7 = 3x + -5
Reorder the terms:
7 + 5x = 3x + -5
Reorder the terms:
7 + 5x = -5 + 3x
Solving
7 + 5x = -5 + 3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3x' to each side of the equation.
7 + 5x + -3x = -5 + 3x + -3x
Combine like terms: 5x + -3x = 2x
7 + 2x = -5 + 3x + -3x
Combine like terms: 3x + -3x = 0
7 + 2x = -5 + 0
7 + 2x = -5
Add '-7' to each side of the equation.
7 + -7 + 2x = -5 + -7
Combine like terms: 7 + -7 = 0
0 + 2x = -5 + -7
2x = -5 + -7
Combine like terms: -5 + -7 = -12
2x = -12
Divide each side by '2'.
x = -6
Simplifying
x = -6
