Answer:
x2 +2x−xy when x = 250 and y = −120 ... sic Algebra: Patterns and Equations (13:18)
Step-by-step explanation:
The quantity of each type of seats sold are as follows:
- Movie and a dinner seat = 200
According to the question,there are four times as many 3D, x seats as Dinner and a Movie, y seats.
That is, x = 4y
Also, total seats
= (x) + (y) + (z) = 3000...….............eqn(1)
Also, If the theater brings in $53,000 when tickets to all 3000 seats are sold.
- 20x + 35y + 15z = 53000...........eqn(2)
By substituting 4y for x in equations 1 and 2; we have;
<em>5y + z = 3000</em>..…........eqn(3) and
<em>115y + 15z = 53000</em>.........eqn(4)
By solving equations 3 and 4 simultaneously; we have;
y = 200 and z = 2000
and since x = 4y
x = 800
The quantity of each type of seats sold is as follows:
- Movie and a dinner seat = 200

Answer:
x= 1/256
Step-by-step explanation:
1. multiply both sides by 8x (answer: -5= 8x*-160)
2. divide both sides by -160 (answer: -5/-160 or 1/32 =8x)
3. divide both sides by 8 (answer: 1/256 = x
4. check your answer: -5/(8*1/256)= -160
