Let x stand for a movie.
You can pay $4 every movie or $1.50 for every movie plus the original $10
4x = 1.50x +10
-1.50x -1.50x (Subtraction Property of Equality)
2.50x = 10
/2.50 /2.50 (Division Property of Equality)
x = 4
After 4 movies, the membership will cost less.
Answer:
Equation to solve is x+x+120=180
Solution to equation: x=30
Step-by-step explanation:
The angles in a triangle have a sum 180 degrees.
You know one angle is 120 degrees.
If you assume another angle has a measurement of x degrees, then the remaining angle has a measurement of x degrees. We know this because congruent means they will have the same measurement.
So we have this equation to solve:
x+x+120=180
Combine like terms:
2x+120=180
Subtract 120 on both sides:
2x=180-120
Simplify:
2x=60
Divide both sides by 2:
x=60/2
Simplify:
x=30
