If the number of $8 child tickets is 17 less than 3 times the number of $12 adult tickets and the theater took in $584, how many
NISA [10]

Answer:

The number of child tickets sold was 43 and the number of adult tickets sold was 20

Step-by-step explanation:

Let

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

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

we know that

x=3y-17 -----> equation A

8x+12y=584 ----> equation B

Solve the system by graphing

Remember that the solution is the intersection point both graphs

The solution is the point (43,20)

see the attached figure

therefore

The number of child tickets sold was 43 and the number of adult tickets sold was 20

Two equations are given below: a – 3b = 22 a = b – 2 What is the solution to the set of equations in the form (a, b)? (–10, –8)
aliya0001 [1]
Hi Kristian

a - 3b = 22
a = b - 2

We need to solve a = b -2 for a
First, we need to substitute b - 2 for a in a - 3b = 22
a - 3b = 22
b - 2 - 3b = 22
-2b - 2 = 22
 -2b = 22 + 2
-2b = 24
b = 24/-2
b = -12

Now substitute -12 for b in a = b - 2
a = b -2
a= -12 - 2
a= -14

Thus, the solution is a = -14 and b = -12

The correct option is the last one (-14,-12)


If you have questions about my answer, please let me know.


Good luck!

Your club is selling hats and t-shirts to raise money for juvenile diabetes. You have already spent $240 on the hats and t-shirt
Arlecino [84]

The number of hats sold = x

The number of t-shirts sold = y

Cost of selling of each hat = $5 and

Cost of selling of each t-shirt = $12.

Cost of x hats at the rate $5 each = 5x and

Cost of y t-shirts at the rate $12 each = 12y.

Total cost of x hats and y t-shirts = 5x+12y.

Total amount was spent = $240.

Therefore,<em> cost of x hats and y t-shirts should be greater than or equal to 240.</em>

<h3>So, the inequality for the situation would be </h3><h3>5x+12y ≥ 240.</h3>
