On the first day, 8 adult tickets were sold and 13 student tickets were sold for a total of $75. On day two, 10 adult tickets were sold and 9 student tickets were sold for a total of $72. What is the cost of an adult ticket? What is the cost of a student ticket?
Answer:
Adult ticket = $4,5
Student ticket = $3
.
Step-by-step explanation:
Let say adult ticket is x and student ticket is y. so we get:
→ 8x + 13y = 75 (×5) 40x + 65y = 375
→ 10x + 9y = 72 (×4) 40x + 36y = 288
.
Eliminate both equations
40x + 65y = 375
40x + 36y = 288
29y = 87
[tex]y = \frac{87}{29}[/tex]
[tex]y = 3[/tex]
.
Substitute the value of y to one of equations
[tex]10x + 9(3) = 72[/tex]
[tex]10x + 27 = 72[/tex]
[tex]10x = 72 - 27[/tex]
[tex]10x = 45[/tex]
[tex]x = \frac{45}{10}[/tex]
[tex]x = 4,5[/tex]
.

a coin jar holds dimes and quarters.A coin jar holds dimes and quarters. There are ten less quarters than dimes. There is a total of $3.80. How many dimes are in the jar
Answer:
There are 18 dimes in the jar
Step-by-step explanation:
Let
x = number of dimes in the jar
y = number of quarters in the jar
Total = $3.80
There are ten less quarters than dimes
y = x - 10
0.1x + 0.25y = 3.80
0.1x + 0.25(x - 10) = 3.80
0.1x + 0.25x - 2.5 = 3.80
0.35x = 3.80 + 2.5
0.35x = 6.30
x = 6.30/0.35
x = 18

what is the percent change of 44000 to 40000
Answer:
10 percent
Step-by-step explanation:
40000 is the old value and 44000 is the new value. In this case we have a positive change (increase) of 10 percent because the new value is greater than the old value.
f(n) = n^3– 2n
g(n)= 2n + 2
Find (f •g)(n)
Answer:
[tex]\boxed{(f~.~g)(x) = 2n^4 + 2n^3 - 4n^2 -4n}[/tex]
.
Step-by-step explanation:
We know that
[tex]f(n) = n^3 - 2n[/tex]
[tex]g(n) = 2n + 2[/tex]
.
So
[tex](f~.~g)(x) = f(n)~.~g(n)[/tex]
[tex](f~.~g)(x) = (n^3-2n)(2n + 2)[/tex]
[tex](f~.~g)(x) = n^3(2n + 2) - 2n(2n + 2)[/tex]
[tex](f~.~g)(x) = 2n^4 + 2n^3 - 4n^2 -4n[/tex]

Use the algebraic expressions for the length and width of Marlene's living room found in the
23.
diagram and the value of x found in Question 21C.
A. Find the actual length and width of her living room.
B
Find the actual area of Marlene's living room. Use actual dimensions.
Answer:
The area of Marlien's living room is 420 square ft
Step-by-step explanation:
Before calculating the real dimensions of Marlien's living room, we must find the value of x.
Given the total shape of the house is a rectangle, then both widths must be equal and both lengths must be equal.
The widths are already written width identical expressions x-2+x, but the lengths are given as different functions of x. Equating both expressions, we have:
[tex]2x-10+x-2+\frac{1}{2}x-4+x-2=2x+2+\frac{1}{2}x-4+x-2[/tex]
Simplifying:
-10 + x - 2 = 2
x = 10 + 2 + 2
x = 14
Since x=14 feet, the dimensions of Marlien's living room are
width=x=14 feet
length=2x+2=30 feet
Thus the area is:
A = 14*30 = 420 square ft
The area of Marlien's living room is 420 square ft
If a polynomial 2x( raised to power 3) -9x +15x +p, when divided by (x-2), leaves -p as remainder, then p is equal
Answer:
p is -5
Step-by-step explanation:
If a polynomial 2x³-9x² +15x +p is divided by (x-2), then the remainder is gotten by equating the divisor x - 2 to zero
If x - 2 = 0
Add 2 to both sides
x - 2 + 2 = 0 + 2
x = 2
Substitute x = 2 into the expression to get the remainder:
If p(x) = 2x³-9x² +15x +p
p(2)= 2(2)³-9(2)² +15(2) +p
p(2) = 2(8) - 9(4) + 30 + p
p(2) = 16-36+30+p
p(2) = -20 + 30 + p
p(2) = 10+p
Since the remainder given in question is - p, to get p, we will equate p(2) to -p as shown
p(2) = -p
10+p = -p
10 = -p-p
10 = -2p
p = 10/-2
p = -5
Hence the value of p is -5

Select all of the following that are quadratic equations.
1. x2 + 3 x -5 = 0
2. x2 - x = 3 x + 7
3. 5 x - 7 = 0
4. 7 x2 + 14 x = 0
5. x3 - 3 x2 + 1 = 0
6. x - 5 = 9 x + 7
Answer:
1. x² + 3x - 5 = 0
2. x² - x = 3 x + 7
4. 7x² + 14x = 0
Step-by-step explanation:
A Quadratic equation takes the form;
ax² + bx + c = 0
a, b, c are constants and a cannot be 0.
Options 1 fits this;
x² + 3x - 5 = 0
Option 2 fits this as well;
x² - x = 3 x + 7
x² -x - 3x - 7 = 0
x² - 4x - 7 = 0
Option 4 fits this as well if c = 0.
7x² + 14x + 0 = 0

The density of platinum is approximately 21 grams per cmº.
Which of the items cannot be platinum?
You must show your working.
Answer: Multiply the density with the volume. You get 2418.2 grams or 2.4182 kilograms
Step-by-step explanation:
Answer:
Item B
Step-by-step explanation:
A:
density = mas/volume = 42 g / 2 cm^3 = 21 g/cm^3
This may be platinum.
B.
density = mass/volume = 87.5 g / 5 cm^3 = 17.5 g/cm^3
This cannot be pure platinum.
C.
density = mass/volume = 147 g / 7 cm^3 = 21 g/cm^3
This may be platinum.
Answer: Item B
Solve for the variable x.
4(x - 11) = -210
Answer: Divide both sides by the numeric factor on the left side, then solve.
Exact Form: x= −83/2
Answer: x = -41.5
Step-by-step explanation:
Distribute the 4 that is outside of the parentheses.
4 times x = 4x
4 times -11 = -44
Then to isolate the variable add 44 to both sides of the equation to cancel out -44.
-44 + 44 = 0
-210 + 44 = -166
Now your equation should 4x = -166
To find x, divide both sides of the equation by 4.
4x divded by 4 is x.
-166 divded by 4 is -41.5.
So the answer is x = -41.5.
To check the answer, plug in -41.5 to the x.
4(-41.5 - 11) = -210
Jack bought 3 pairs of socks for $7.50. At this rate, how much would 10 pairs of socks cost?
Answer:

A company charges a shipping fee that is 4% of the purchase price for all items
it ships. What is the fee to ship an item that costs $66?
Company sells drinks in packs and cases a bottle is 1/6 of pack and the pack is 1/12 of a case a case of the drink called 25.92 what is the price per bottle in a case
Answer:
0.36
Step-by-step explanation:
Company sells drinks in packs and cases a bottle is 1/6 of pack and the pack is 1/12 of a case a case of the drink called 25.92 what is the price per bottle in a case
From the above question:
1 pack = 1/12 of a case.
1/12 of a case = 1 pack
1 case = x packs
Cross Multiply
1/12 × x = 1 × 1
x = 1 / 1/12
x = 1 × 12/1
x = 12 packs
This means, 1 case of drinks contains 12 packs of drinks
We are also told that: a case of the drink cost 25.92
This means the cost of 12 packs of drinks = 25.92
We are also told that:
a bottle is 1/6 of pack
1/6 pack = 1 bottle
1 pack = x bottles
Cross Multiply
1/6 × x = 1 × 1
x = 1 / 1/6
x = 1 × 6/1
x =6 bottles
This means, 1 pack of drinks contains 6 bottles of drinks
Hence:
12 packs of drinks = 25.92
1 pack of drinks = x
Cross Multiply
12x = 25.92
x = 25.92/12
x = 2.16
1 pack of drinks cost 2.16= 6 bottles of drinks cost 2.16
Therefore:
6 bottles of drinks = 2.16
1 bottle of drink = x
Cross Multiply
6x = 1 × 2.16
x = 2.16/6
x = 0.36
Therefore, the price per bottle in a case is 0.36
