Answer:
p = 14
Equation:
[tex]156=12x+6p[/tex]
Step-by-step explanation:
Set up the equation:
Let x = # of friends that went to the movies
Let p = cost of 1 popcorn
[tex]156=12(6)+6p[/tex]
[tex]156=72+6p\\84=6p[/tex]
Divide both sides by 6
[tex]p=14[/tex]

Solve x÷2<4. Graph the solution.
Answer:
The solutions are (-2, 0) and (1, 3).
Step-by-step explanation:
Edginuity Sample response: The graph consists of a parabola and a line. The parabola opens down and has a vertex of (0, 4). The line has a slope of 1 and a y-intercept of 2. We want to solve
-x² + 4 = x + 2
Create two curves as follows:
y = -x² +4
and
y = x + 2
By graphing the two curves together, their points of intersection are the solutions.
y = -x² + 4 is a parabola with vertex at (0, 4), and it opens downward.
y = x + 2 is a straight line with slope - 1 and with y-intercept = 2
The points of intersection are (-2, 0) and (1, 3).
Given a geometric sequence with a1=5 and a4=135 find a2.
Answer:
15
Step-by-step explanation:
Terms in a geometric series that are n apart will have a ratio that is r^n. Here we have terms a4 and a1, which are 4-1=3 apart, so their ratio is ...
a4/a1 = 135/5 = 27 = r^3
r = ∛27 = 3
The second term is the first, multiplied by this common ratio:
a2 = a1·r = 3(5)
a2 = 15
A family of 2 children and 1 adult visited an amusement park and paid an entry fee of $90. Another family of 3 children and 2 adults visited the same amusement park and paid an entry fee of $155. What is the entry fee for a child at the amusement park?
[tex]\underline{\underline{\large\bf{Solution:-}}}\\[/tex]
[tex]\leadsto[/tex]Let us assume entry fee for child be x
[tex]\leadsto[/tex]Let us assume entry fee for adult be y
[tex]\\[/tex]
[tex]\longrightarrow[/tex]Since Entry fees for 2 children and 1 adult is $90 an equation for entry fees will be formed as -
[tex]\begin{gathered}\\\implies\quad \sf 2\times x + 1 \times y = 90 \\\end{gathered} [/tex]
[tex]\begin{gathered}\\\implies\quad \sf 2 x + y = 90 \\\end{gathered} \_\_\_\_\_(1) [/tex]
[tex]\longrightarrow[/tex]Similarly, Entry fees for 3 children and 2 adult is $155 , so an equation for entry fees will be formed as -
[tex]\begin{gathered}\\\implies\quad \sf 3\times x + 2\times y = 155 \\\end{gathered} [/tex]
[tex]\begin{gathered}\\\implies\quad \sf 3x + 2y = 155 \\\end{gathered} \_\_\_\_\_(2) [/tex]
Multiplying eq (1) by 2 it will be -
[tex]\begin{gathered}\\\implies\quad \sf 4x + 2y = 180\\\end{gathered}\_\_\_\_\_(3) [/tex]
Subtracting eq(2) from eq(3) -
[tex]\begin{gathered}\\\implies\quad \sf 4x+2y - (3x+2y) = 180-155\\\end{gathered} [/tex]
[tex]\begin{gathered}\\\implies\quad \sf 4x + 2y - 3x - 2y = 35\\\end{gathered} [/tex]
[tex]\begin{gathered}\\\implies\quad \sf 4x - 3x +2y- 2y = 35\\\end{gathered} [/tex]
[tex]\begin{gathered}\\\implies\quad \bf x = 35\\\end{gathered} [/tex]
Thus , entry fee for a child at the amusement park = $ 35
Noel's age in 8 years will be three times as old as it was 2 years ago. How old is Noel now?
Answer:
6
Step-by-step explanation:
let Noel's age be x
if Noel's age in 8 years will be three+times as old as it was 2 years ago:
x%2B8=3%28x-2%29
x%2B8=3x-6
6%2B8=3x-x
2x=14
x=7
Noel is 7 years old now

Norton started driving at 9 am by noon he had traveled 162 mi what was his average speed?
Answer:
54mph (or 54 mi/h)
Step-by-step explanation:
9 am to the noon is 3 hours.
S=d/t where S=average speed, d=distance, and t=time
S=162/3=54
Hope that helps!!!
Answer:
54 mph
Step-by-step explanation:
Noon is at 12:00 so if he started at 9:00 he would have droven 3 hours and 162 divided by 3 = 54. This is correct

Answer:
k=−(x−h) 2+r 2 +y
Step-by-step explanation:
Subtract (x−h) from both sides of the equation.
Subtracting (x−h) from itself leaves 0.
Subtract (x−h)from r
Take the square root of both sides of the equation.
Subtract y from both sides of the equation.
subtracting y from itself leaves 0.
Dividing by −1 undoes the multiplication by −1.

Step-by-step explanation:
The local furniture store pays $120 for a lamp and sells it with a 20% markdown. What is the
selling price of the lamp?
Answer:$24
Step-by-step explanation:
To find 20 percent of a number you multiply the number by 20, then multiply the answer by .01.
120 x 20 = 2400
2400 x .01 = 24
Answer: I think its 24 tell me if I'm wrong
20 divided by 100 gives you 0.2
0.2x120 gives you 24
Two crocodiles together can finish their snacks in 40 seconds
Answer:
That is an interesting fact! Thank you. If you need help, let me know and I may be able to help.
[tex]:)[/tex]
The time it will take the second crocodile to finish its snack is 120 seconds
Ratio and proportionsLet x represent the rate of the first crocodile and let y represent the rate of the second crocodile.
The two crocodiles working together can finish a snack in 40 seconds. Thus;
(1/x + 1/y)40 = 1
It takes one of the crocodiles 60 seconds to finish its snack. Thus;
(1/x + 1/60)40 = 1
40/x + 2/3 = 1
x = 120 seconds

Complete question:
Two crocodiles together can finish their snack in 40 seconds. one of the crocodiles can finish the snack in 60 seconds. how long will it take the second crocodile to finish the same snack?
solve for
7c+5=9(c−3)
Answer:
c = 16
Step-by-step explanation:
First, distribute the 9 to the parentheses:
7c + 5 = 9(c − 3)
7c + 5 = 9c - 27
Then, subtract 7c from both sides:
5 = 2c - 27
Add 27 to both sides:
32 = 2c
Divide each side by 2:
16 = c
So, c = 16
What is the answer to this quadratic equation: 6x² + 11x – 35
Answer:
Step-by-step explanation:
This thing looks like you have to use the quadratic equation to solve it. You don't. It will factor. but you might have to guess a bit.
(3x )(2x )
(3x - 5 ) (2x + 7) How lucky is that!!?
Remove the Brackets
3x * 2x + 3x*7 - 5*2x - 35 Combine
2x*3x^2 + 21x - 10x - 35
6x^2 + 11x - 35
So the guess turns out to be correct. Now we need to solve for the roots.
3x - 5 = 0 Add 5 to both sides.
3x = 5 Divide by 3
x = 5/3
x = 1.6667
2x + 7 = 0 Subtract 7 from both sides
2x = - 7 Divide by 2
2x/2 = - 7/2
x = - 3.5
Answer
x = 1.667 orx = - 3.5
