Your friend sells "for"adult tickets and 15 student tickets for $27, I think you meant "four" adult tickets and 15 student tickets for $27.
Answer:Adult ticket costs $3
Student ticket cost $1
Step-by-step explanation:
Let the cost adult ticket be represented as X
And cost student tickets be represented as y
Such that two adult tickets and six student tickets for $12 would be expressed as
2x+6y=12
And
four adult tickets and 15 student tickets for $27.
4x+15y=27
The equations to solve becomes
2x+6y=12-----equation 1
4x+15y=27------equation2
Solving
Multiply equation 1by 4 and equation 2by 2
8x+24y=48---equation 3
8x+30y=54-----equation4
Subtracting equation 3from equation 4
6y=6
Y=6/6
Y=1
Putting the value of y=1in equation 1and solving for x becomes
2x+6y=12
2x+6x1=12
2x=12-6
2x=6
X=6/2=3
Adult ticket costs $3
Student ticket cost $1
What is 3y - 2x = 9 in slope intercept form?

Answer:
Trapezoid
Step-by-step explanation:
They're showing us (with red arrows/triangles) that the bottom and top are parallel, but do not state anything like it for the sides.
That means it's at least a trapezoid.
As nothing suggests the sides are parallel, it's likely not a parallelogram (and it doesn't look like one).
It's also not a kite, as there is no indication that pairs of neighboring sides are equal in length.
As we don't think it's a parallelogram, it's thus not a rectangle (every rectangle is a parallelogram).
Similar with rhombus (every rhombus is a parallelogram) and square (every square is a parallelogram AND a rhombus).
Which pair of terms are NOT like terms?

Step-by-step explanation:
There are 6 animals in the pen some are quails and some are goats if there are 20 legs in all how many quails and how many goats are there?
Answer:
4 goats
Step-by-step explanation:
Let us represent
Number of quails = x
Number of goats = y
Quails have 2 legs
Goats have 4 legs
Hence:
There are 6 animals in the pen some are quails and some are goats
x + y = 6...... Equation 1
x = 6 - y
if there are 20 legs in all how many quails
2x + 4y = 20..... Equation 2
We substitute 6 - y for x in Equation 2
2(6 - y) + 4y = 20
12 - 2y + 4y = 20
Collect like terms
- 2y + 4y = 20 - 12
2y = 8
y = 8/2
y = 4 goats
The number of goats there are 4 goats

A tree casts a shadow that is 9 meters long. A 54 meter tall building nearby casts a shadow that is 24 meters long. What is the height of the tree
Answer:
Height of the tree is 20.25 m.
Step-by-step explanation:
Length of building AB = 54 m
Length of tree DE = 9 m
Shadow casted by the building (BC) = 24 m
Shadow casted by the tree (CE) = 9 m
Since, ΔABC ~ ΔDEC
By the property of similar triangles, corresponding sides of the similar triangles will be proportional.
[tex]\frac{AB}{DE}=\frac{BC}{EC}[/tex]
[tex]\frac{54}{h}=\frac{24}{9}[/tex]
h = [tex]\frac{54\times 9}{24}[/tex]
h = 20.25 m
Therefore, height of the tree is 20.25 m.

Mr. Philps made 1 gallon of fruit punch for his class party. If he has 27 students, and each of them will drink 1 cup, will he have enough
Answer:
1st question: 13 questions
2nd question: Mr.Philps will not have enough
Step-by-step explanation:
Mateo and Logan finished 65% of their math homework. If it has 20 problems, how many problems have they done?
20 x 0.65 = 13
Mr. Philps made 1 gallon of fruit punch for his class party. If he has 27 students, and each of them will drink 1 cup, will he have enough?
1 gallon = 16 cups
27 students x 1 cup each = 27 cups
27 is greater than 16, so no, he will not have enough.

-3 - (-9)
Answer:
-3 - (-9)
As we have '-' sign outside bracket, the sign inside the brackert will become opposite, thus we will have,
⇒ -3+9
⇒ 6
-3 - (-9) change the signs -3+9 then calculate which gives your answer 6
Can someone help me solve this problem?
Answer:
a = 8
b = 4[tex]\sqrt{2}[/tex]
Step-by-step explanation:
I've attached a picture of the 45-45-90 triangle's formula, which is the length of the hypotenuse = [tex]\sqrt{2}[/tex] times the length of a leg (one of the sides of the triangle).
So, applying this to your problem, if 4[tex]\sqrt{2}[/tex] if one of the legs of the triangle, the other leg, which is b , would be the same length.
b = 4[tex]\sqrt{2}[/tex]
To solve for a, you would have to multiply the leg by [tex]\sqrt{2}[/tex].
a = 4[tex]\sqrt{2}[/tex] x [tex]\sqrt{2}[/tex]
I would separate the 4 and the [tex]\sqrt{2}[/tex].
a = 4 x [tex]\sqrt{2}[/tex] x [tex]\sqrt{2}[/tex]
a = 4 x [tex]\sqrt{2 *2}[/tex]
a = 4 x [tex]\sqrt{4}[/tex]
a = 4 x 2
a= 8

Water and oil are mixed in the ratio 3:5. Find the density of the mixture if the density of water is 1g/cm ^3 and that of oil is 0.8g/cm^3
Answer:
Density of mixture is 7.0 g/[tex]cm^{3}[/tex].
Step-by-step explanation:
Density of mixture = density of water in the mixture + density of oil in the mixture
Given: water and oil were mixed in a ratio 3:5
density of water is 1.0 g/[tex]cm^{3}[/tex] and that of oil is 0.8 g/[tex]cm^{3}[/tex].
Then,
density of water in the mixture = 3 x 1.0 g/[tex]cm^{3}[/tex]
= 3.0 g/[tex]cm^{3}[/tex]
Density of the volume of water in the mixture is 3.0 g/[tex]cm^{3}[/tex].
density of oil in the mixture = 5 x 0.8 g/[tex]cm^{3}[/tex]
= 4.0 g/[tex]cm^{3}[/tex]
Density of oil in the mixture is 3.0 g/[tex]cm^{3}[/tex].
So that,
Density of mixture = 3.0 + 4.0
= 7.0
Density of mixture is 7.0 g/[tex]cm^{3}[/tex].
⦟KLJ and ⦟JLM are a linear pair. Find the measures of ⦟KLJ and ⦟JLM.
m⦟KJL = __°
m⦟JLM = __°
Pic:
Answer:
Step-by-step explanation:
6x + 12 + 4x + 8 = 180 {Linear pair}
6x + 4x + 12 + 8 = 180 {Combine like terms}
10x + 20 = 180 {Subtract 20 from both sides}
10x = 180 - 20
10x = 160 {Divide both sides by 10}
x = 160/10
x = 16
m∠KLJ = 6*16 + 12
= 96 +12
= 108
m∠JLM = 4*16 + 8
= 64 + 8
= 72
Answer:
∠ KLJ = 108° , ∠ JLM = 72°
Step-by-step explanation:
Since the angles are a linear pair they sum to 180° , then
6x + 12 + 4x + 8 = 180
10x + 20 = 180 ( subtract 20 from both sides )
10x = 160 ( divide both sides by 10 )
x = 16
Then
∠ KLJ = 6x + 12 = 6(16) + 12 = 96 + 12 = 108°
∠ JLM = 4x + 8 = 4(16) + 8 = 64 + 8 = 72°
