Answer:
20 movies ; $70
Step-by-step explanation:
Company 1:
Monthly charge = $40 ; additional = 1.5 per movie
Let number of movies = x ; t = cost
Equation 1:
y = 40 + 1.5x
Company 2:
Monthly charge = $30
Additional = $2 per movie
Equation 2:
y = 30 + 2x
1) for equation 1 = equation 2
40 + 1.5x = 30 + 2x
40 - 30 = 2x - 1.5x
10 = 0.5x
x = 10/0.5
x = 20
Hence, 20 movies
B.)
y = 30 + 2x
y = 30 + 2(20)
y = 30 + 40
y = $70
Answer:
4 over 5 {4/5}
Step-by-step explanation:
4/10 + 4/10 is 8/10, divide both by 2 and you get 4/5
Answer:
3x-2c=5
3x=5-2c
x=<u>5</u><u>-</u><u>2</u><u>c</u>
3
3x=45
To solve for X, divide both sides of the equation by 3:
3x / 3 = 45 / 3
x = 15
Answer:
1) x = 2
