X=3y+5 → x-3y=5 ..(1)
x-4y=3 ..(2)
→The second <span>equation we must multiplication by (-1)
→x-3y=5
→-x+4y=-3
x's is lost..
4y-3y=5-3
y=2
x-3.2=5
x=5+6=11</span>
Answer:
Step-by-step explanation:
Let x represent the rate at which the ticket is sold and let y represent the number of tickets sold at that rate.
When x = 4, y = 800
This means that the income from gate takings at this rate is 4 × 800 = $3200
For each 1 dollar increase in the gate fee,management expects 100 fewer customers to buy tickets. It means that the amount earned would be (x + 1)(y - 100)
For the amount to be $3500, it means that
(x + 1)(800 - 100) = 3500
700(x + 1) = 3500
x + 1 = 3500/700 = 5
Therefore, management should charge $5 per person for gate fee so that it collects 3500 dollars from gate takings.
the answer to ur question is -4 hope this helps
Answer:
The value of x=12
Step-by-step explanation:
because the whole thing is 90 and the other angles are equal to 78 if you add them together. So you would subtract 90-78 which equals 12.
