a total of 442 tickets were sold for the school play. They were either adult tickets or student tickets. There were 58 fewer

Answers

Complete Question:

A total of 442 tickets were sold for the school play. They were either adult tickets or student tickets. There were 58 fewer

There were 58 fewer student tickets sold than adult tickets. How many adult tickets were sold?

Answer:

250 adults tickets

Step-by-step explanation:

Given

Represent Adult with A and Children with C

$Total = 442$

$A = C + 58$

Required

Find A

Since the ticket were either bought by A or C; then

$A + C = Total$

This gives:

$A + C = 442$

Substitute C + 58 for A

$C + 58 + C = 442$

Collect Like Terms

$C + C = 442 - 58$

$2C = 384$

Divide through by 2

$C = 192$

Recall that:

$A = C + 58$

$A = 192 + 58$

$A = 250$

Hence, 250 adults bought the ticket

There were 192 adult tickets and 250 student tickets sold for the school play, totaling 442 tickets.

Let's denote the number of adult tickets sold as "A" and the number of student tickets sold as "S." According to the information provided, we have two equations:
A + S = 442 (since a total of 442 tickets were sold).
A = S - 58 (since there were 58 fewer adult tickets than student tickets).
Now, we can use a system of equations to solve for A and S. We can substitute the value of A from the second equation into the first equation:
(S - 58) + S = 442
Combine like terms:
2S - 58 = 442
Add 58 to both sides:
2S = 442 + 58
2S = 500
Now, divide by 2 to solve for S:
S = 500 / 2
S = 250
So, there were 250 student tickets sold.
Now, we can find the number of adult tickets (A) using the second equation:
A = S - 58
A = 250 - 58
A = 192
Therefore, 192 adult tickets and 250 student tickets were sold for the school play.

Complete question should be:

How many adult tickets and student tickets were sold for the school play if a total of 442 tickets were sold, and there were 58 fewer adult tickets than student tickets?

Which expression is equal to “7 times the sum of a number and 4"?

Answers

Answer: 7 (x+4)

Step-by-step explanation: Since the expression asks for 7 times the sum of a number and 4, you would put x + 4 in parentheses since multiplying 7 comes afterwards.

What is the domain of the function?Question 2 options:

all real numbers greater than or equal to 1

all real numbers less than or equal to 5

all real numbers less than or equal to 1

all real numbers

Answers

Answer:

"all real numbers"

Step-by-step explanation:

The domain is the set of x-values for which the function is defined.

Domain is also the input of the function (graph).

The graph shown has arrows in both directions. It means that the graph goes on in both directions. If we were to think correctly, we would say the graph would go on-and-on in both +ve x and -ve x directions. So there would be values of x for all real numbers (going to infinity and negative infinity)

Hence, the domain is all real number, the last answer choice is right.

What is the solution to 7.5d=2.5d

Answers

Answer:

d = 0

Step-by-step explanation:

To find the solution to the given equation, we must solve for d in the equation.

7.5d = 2.5d

Subtract 2.5d from both sides.

5d = 0

Divide both sides by 5.

d = 0

So the solution to the equation would be d = 0.

I hope this helps. Happy studying.

Final answer:

The provided equation 7.5d=2.5d seems to be flawed as these quantities cannot be equal unless the variable 'd' is zero. Please double-check the equation.

Explanation:

The equation given is 7.5d=2.5d. However, this equation cannot be correct as 7.5d and 2.5d cannot be equal unless the variable 'd' equals zero. It seems that there's a typo or mistake in the provided equation. The solution could not be found as the equation seems to be flawed. Please double-check the equation and make sure the coefficients (the numbers before the 'd') and the variable 'd' are correct.
