1 answer:

7 0

Y=x-4

From this we plug in the answer to find the y value!

For example y=3-4=-1 A.) would be incorrect!

Y=3-4=-1 B.) would be incorrect!

C.) y= -3-4=-7 while it’s SUPPOSE to be 7.

D.) y= -3-4=-7 and y value is -7

At the movie theatre, child admission is $5.90

Alik [6]

Let the number of children be c, and the number of adults be a.
c + a = 170 (total number of tickets)
Then the cost of each is: $5.90/child, $9.60/adult:
5.9c + 9.6a = 1269.40 (total sales)
Solving as 2 simultaneous equations, we first transform the first equation:
a = 170 - c
Substitute into the 2nd equation:
5.9c + 9.6(170 - c) = 1269.40
Solving gives c = 98, and a = 170 - 98 = 72. This means that 72 adult tickets were sold that day.

At a movie theater, admission tickets cost $10 for adults and $8 for children. On Saturday, Anne Teak collected a total of $1276

kow [346]

Answer:

Part a) variable x (the number of adult tickets sold) and variable y (the number of child tickets sold)

Part b) $10x+8y=1,276$

Part c) The number of adult tickets sold was 86

Step-by-step explanation:

Part a) Name a variable for the number of adult tickets sold and name a variable for the number of child tickets sold

Let

x -----> the number of adult tickets sold

y -----> the number of child tickets sold

Part b) Write an equation in two variables to model the problem

we know that

$10x+8y=1,276$ -----> equation A

$y=52$ -----> equation B

substitute equation B in equation A and solve for x

$10x+8(52)=1,276$

$10x+416=1,276$

Part c) Using your equation in Part B, solve the problem and answer the question "how many adult tickets did Anne sell?" i

we have

$10x+416=1,276$

Solve for x

Subtract 416 both sides

$10x=1,276-416$

$10x=860$

$x=86$

therefore

The number of adult tickets sold was 86

How do you do this ?

Sedaia [141]

This is the answer
first you must eliminate the denominator and that you do with multiplication
then eliminate the number that is on the same side of the letter and that you do it by placing the same number but with a different sign and so you have the answer.

also there is the check.
