You basically want to write the total number of people using x and y for children and adults, and then write the cost function using the values you know for the ticket prices. next, you want to want to rearrange your total people equation so that you can write either x in terms of y or y in terms of x. finally, you can plug that into your cost equation and solve. (you then use the rearranged total people equation to solve for the other variable).
hope this helps :)
By direct calculation, we will see that the full price of each necktie is $29.

How to find the complete price of each necktie?</h3>
Let's say that the full price of each necktie is f.
We know that Will each necktie costed $8 less than the full price, so he paid:
(f - $8) for each one.
Knowing that he bought 7 and paid a total of $147, we know that he paid:
$147/7 = $21
Then we need to solve:
(f - $8) = $21
Solving for f, we have:
f = $21 + $8 = $29.
So the full price of each necktie is $29.

Answer:
2(W - 5) ≤ -29
Step-by-step explanation:
"Twice the difference of a number and 5 is at most -29" can be expressed symbolically as follows:
2(W - 5) ≤ -29
Further explanations:
"the difference of a number and 5" is W - 5, and thus "Twice the difference of a number and 5" is 2(W - 5).
"x ≤ -29" states "x is at most -29."
Answer:
q = r
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given 2q – r = 4p ...(i)
2r = q...(ii)
r = 2p ...(iii)
Substitute 2r = q in equation (i)
<em> 2(2r) – r = 4p </em>
3 r = 4 p
<em> 2 r + r = 4 p</em>
2 r + 2 p = 4 p
2 r = 2 p
<em> q = r</em>
The slope is -2:) hope this helped!!
