P + s = 200......p = 200 - s
20p + 15s = 3400
20(200 - s) + 15s = 3400
4000 - 20s + 15s = 3400
-20s + 15s = 3400 - 4000
-5s = - 600
s = -600/-5
s = 120 <=== there were 120 standard tickets sold
p + s = 200
p + 120 = 200
p = 200 - 120
p = 80 <=== there were 80 premium tickets sold
Answer:
38 sq cm.
Step-by-step explanation:
Find the triangles:
1st: 10
2nd: 1/2(8-6)*4=4
Rectangle area: 24, add together 10+4+24=38 sq cm.
To solve for a variable means to ISOLATE the variable on one side of the equation. To do so, divide both sides by the coefficient of y.
Look:
2y/2 = (-x+7)/2
Answer: y = (-x + 7)/2
The answer can also be written as
y = -(x/2) + (7/2)
Both answers mean the same thing.
