The expression 15a+12c is the cost of admission at an amusement park for a adults and c chldren. Then find the total cost for 5
siniylev [52]

We are given expression for cost of admission at an amusement park : 15a+12c.

Where a is the number of adults and

c is the number of children.

We need to find the total cost of 5 adults and for 10 children.

<em>In order to find the total cost of 5 adults and for 10 children, we need to plug a=5 and c=10 in 15a+12c expression.</em>

Plugging a=5 and c=10 in 15a+12c expression, we get

15(5) + 12(10) = 75 + 120 = $195.

<h3>Therefore, the total cost for 5 adults and for 10 children is $195.</h3>

Please help<br> Value of x<br> and what are angles m thank you!
Usimov [2.4K]

To find the value of x, you want to use the vertical angles theorem.

The vertical angles theorem says that all vertical angles (which is what TRY and QRW are) are congruent to each other. Knowing this you can make an equation where the angles are equal to each other to find the value of x.

TRY = QRW, so:

(x+16) = (4x-5)

1. Add 5 to both sides.

(x+21) = (4x)

2. You can get rid of the parentheses.

x+21 = 4x

3. Subtract x from both sides.

21 = 3x

4. Divide both sides by 3, isolating x.

7 = x

5. Flip this equation around, so:

x = 7

xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

To find the measure of TRY then plug x into the expression for TRY, which is (x+16).

TRY => ((7)+16) = 23

Since TRY is 23, the vertical angles theorem says that QRW is also 23. Add these measures up.

23+23 = 46

A line's measure is 180 degrees, so two lines would add up to 360 degrees. Subtract 46 from 360 to find the remaining degrees.

360-46 = 314

TRQ and YRW must be congruent to each other so that means you can divide 314 by 2.

314/2 = 157

xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

Answers are:

TRY = 23

TRQ = 157
