Adult tickets to a play cost $1.75 each and student tickets cost $1.25 each. Suppose there are twice as many student tickets sol
nikitadnepr [17]

Answer: the number of adult tickets sold is 400

the number of student tickets sold is 200

Step-by-step explanation:

Let x represent the number of adult tickets sold at the play.

Let y represent the number of student tickets sold at the play.

Adult tickets to a play cost $1.75 each and student tickets cost $1.25 each. If the income from the play was $1,700, it means that

1.75x + 1.25y = 1700 - - - - - - - - - -1

Suppose there are twice as many student tickets sold as adult tickets. This means that

y = 2x

Substituting y = 2x into equation 1, it becomes

1.75x + 1.25 × 2x = 1700= 1700

1.75y + 2.5y = 1700

4.25y = 1700

y = 1700/4.25 = 400

x = y/2 = 400/2 = 200

Write an equation of a line that has the same slope as 2x – 5y = 12 and the same y-intercept as 4y + 24 = 5x.
Alekssandra [29.7K]
In ax+by=c form
slope=-a/b

y intercept is when x=0


sloope of 2x-5y=12 is -2/-5=2/5

y intercept of 4y+24=5x
4y+24=5(0)
4y+24=0
4y=-24
y=-6
y int=-6

y=mx+b
m=slope
b=y intercept
y=2/5x-6

answer is 2nd optoin

suppose the leftmost digits of two numbers are 8 and 3. can you tell which number is greater? explain.
Debora [2.8K]
You cannot tell which number is greater because you don't know how many numbers follow after 8 or 3. It all depends on how many numbers follow afterwards.
Example: 
It could be 800 or 80,000
It could be 30,000 or 300,000

~ I hope you get what I mean. If you have any more questions, I'd be happy to help!<span />

Now find the change in x. The change in x is . The average rate of change of f(x) = x2 + 5x −−12 from x = −2 to x = 1 is
Ahat [919]

Answer:

The average rate of change = 4.

Step-by-step explanation:

Here we have formula.

Average rate of change = f(b) - f(a)

                                           -----------

                                            b - a

Given: f(X) = x^2 + 5x - 12 interval [-2, 1]

Here a = -2 and b = 1

f(a) = f(-2) = (-2)^2 + 5(-2) -12

= 4 -10 -12

f(-2) = -18

f(b) = f(1) = (1)^2 + 5(1) - 12

= 1 + 5 -12

f(1) = 6 -12

f(1) = -6

Now apply these values in the above formula, we get

Average rate of change = [-6 - (-18)] / [1 -(-2)]

= [ -6 +18]/1 +2

= 12/3

= 4.

Therefore, the average rate of change = 4.

Hope this will helpful.

Thank you.
