Answer:
87 Adult tickets were sold
Step-by-step explanation:
This type of question relates to a system of equations. These types of questions are pretty easy to spot and they are just about solved all the same way.
So what we first want to do is see that there is a total of 159 tickets sold. Now obviously that number consists of the adult and children tickets, therefore we need to add those two unknown numbers to get 159, so x will be for adults and y will be for children tickets. this will give us the equation x + y= 159.
Next, we want to associate the amount those tickets are with those variables, because you can only have so many adult tickets and children tickets with the given $1794. So what we need to do is similar, we just have those totals added to get the equation 14x + 8y = 1794.
Now we want to use the process of elimination to find the value of x (because we are solving how many adult tickets were sold). IN order to do elimination, we need to have the equation x + y= 159 cancel the y value to leave us with the x value. In order to do this, you need to multiply y by a value that cancels 8y in 14x + 8y = 1794, which is -8.
So we multiply the entire equation of x + y= 159 by -8 to get. Now we would add these equations together where you subtract by like terms so:
[tex]14x + 8y = 1794\\-8x - 8y = -1272[/tex]
This leaves us with 6x=522 now you would divide by 6 to isolate x which leaves you with 87.

Answer:
135°Step-by-step explanation:
ΔQPRAll interior angles are equal, so:
m∠QPR = 180°/3 = 60°ΔPRSEquilateral right triangle, so:
m∠RPS = 90°/2 = 45°ΔPSTRight triangle with m∠T = 60°, so:
m∠SPT = 90° - 60° = 30°Now we can find the required angle measure:
m∠QPT = m∠QPR + m∠RPS + m∠SPTm∠QPT = 60° + 45° + 30° = 135°Jose buys cookies and lemons at the store. He pays a total of $30.64. He pays $5.20 for the cookies. He buys 6 bags of lemons that each cost the same amount. Which equation could be used to determine x, how much each bag of lemons costs?
Answer:
$4.24 each
Step-by-step explanation: I did the math. Well but you first subtract the amount of the cookies. Then you have to divided to est of it by six then boom you get the answer.
use the geometric properties and theorems you have learned to solve for x
PLS HELP
Answer: 20
Step-by-step explanation:
*This is a supplementary Angle (adds up to 180 degrees)
5x+12+68=180
5x+80=180
*subtract 80 on both sides
5x=100
*divide both sides by 5
x=20

A proportional relationship goes through the point (4, 10). Explain how to write a function in the form y = mx for this relationship.
Answer:
m = 5 / 2
Step-by-step explanation:
Given
(4, 10)
Here,
x=4 and y=10
Given equation,
y=mx _ equation 1
putting the value of x and y in equation 1. we get,
y = mx
or, 10 = m4
or, 10 / 4 = m
or, 5 / 2 = m
therefore, m = 5 / 2

When solving a two step equation, how do we know which number is the constant?
We know that we have completely solved a two-step equation if the variable, usually represented. Then, we eliminate the number “closest” to the variable.

Karen's music library contains 18 fewer playlists than Clarann's music library. The total number of playlists on both music libraries is 40. Find the number of playlists on each person's music library.
Answer:
let Karen's music library be represented by K
let Clarann's music library be represented by C
C = K +18
C +K =40
put C = K +18 into (C +K =40)
K + 18 +K =40
2K +18 = 40
collect like terms
2K =40 -18
2K =22
divide both sides by 2
K =11
since C = K+18
C= 11 +18
C =29
Karen's music library contains 11 playlists while Clarann's music library contains 29 playlists

To rent a taxi in Los Angeles, the taxi service charges a flat rate of $11.20 and an additional $3.10 per mile driven. Write an equation in slope- intercept form where x represents the distance of the trip, and y represents the amount the taxi service would charge to drive that distance .
Answer:
y = 3.1x + 11.2Step-by-step explanation:
Flat rate is the y- intercept b = 11.2
Charge per mile is the slope m = 3.1
The equation is:
y = 3.1x + 11.2write the question of a line that passes through the point (8,3) and is parallel to the line that passes through the paoints (-5,-1) and (1,-4)
Answer:
y = - 1/2x + 7
Step-by-step explanation:
Slope = (-4 - - 1)/(1 - - 5) = -3/6 = -1/2
Point: (8,3)
b = 3 - (-1/2)(8)
= 3 + 4 = 7

What is the input when f(x)=18?
Answer: The input is 5.
Step-by-step explanation: Since both are functions of f(x), you can set 9x-27 equal to 18 and then solve the equation. 9x-27=18, add 27 to both sides to get 9x=45, divide both sides by 9, x=5.

3/4 divided by 3/16
3/4 times 16/3
reduce
4
Answer: 4
Step-by-step explanation: do the brackets first. which is (1/2 * 3/8) to multiply these two together multiply numerator by numerator and denominator by denominator. Or, top * top / bottom * bottom
so we'd do 1*2 / 3*8. so it would give you 3/16.
now all we have left to do is divide 3/4 by 3/16.
to do this you can multiply by the reciprocal of the second value(3/16 will become 16/3)
now we have [tex]\frac{3}{4}[/tex] * [tex]\frac{16}{3}[/tex] you can cancel out each 3 to give you 1/4 * 16/1
and you can also divide both 16 and 4 by 4 (16/4=4)
this gives you a final equation of 1 * 4 for a final answer of 4

Sun and Spokes sells racing bikes for $1,800. A bicyclist purchases one of the bikes for 30% less
han the retail price. How much did the bicyclist spend on her racing bike?
Answer:
$1,260
Step-by-step explanation:
You first need to find 30% of 1,800, which is 540. And then, because it's 30$ less than retail price, you would need to subtract that from the initial price:
1,800-540 = 1,260

c is correct. To verify this, look at the point (4, 4) on the black graph. For the same x value (4), we have on the red graph the point (4, 2). If we now look at this point (4, 2) on the red graph we see that the y-value (2) is half that of the point (4, -4) on the black graph: f(x) = (1/2)y
