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]

.

Answer:

B

Step-by-step explanation:

Here, we want to calculate the square root of -√- (75)

That will be

-√(25)(-3)

= -5 √(-3)

√(-3) is same as 3i

So we have the root as;

-5i√3

Answer:

1. =     (all numbers powered by zeros are 1)

2. >    (the smaller the number gets when a number powers a fraction)

3. >    (-5)^2 will equal 25 but -5^2 will equal =25

Answer:

1. =

2. >

3. <

Step-by-step explanation:

2.5^0 = 1

1.5^0 = 1

(1/3)^4 = 0.0123

(1/3)^5 = 0.0041

5^1 = 5

-5^2 = 25

Answer:

4x-3=x+2

4x-x=3+2

3x=5

x=5/3

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

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

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.

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]

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

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

Answer:

I think the answer is 12 = 100

Step-by-step explanation:

since 9 = 80 and that is the same for 11, if you do 180 - 80 = 100 which would be the answer for 10 and 12. Thus 12 = 100 based on the info given.

Answer:

25$

Step-by-step explanation:

7.50$ divided by 3 is 2.50$. then 2.50$ times 10 is 25$

Answer:

75$

Step-by-step explanation:

because you multiply 7 x 10 and that equals 70$ and then multiply .50 x 10 and that equals 5$ so 70$ plus 5$ equals 75$

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

Answer:

Rob.

Step-by-step explanation:

If we take Eric's unit rate and multiply the denominator by two, it will be 14 minutes. Rob's denominator is also 14 minutes. This makes it easier on ourselves. If we multiply the bottom number we also have to multiply the top. So, on Eric's unit rate, we will take the 3 pages and mltiply it by 2 to get 6. 6 is less than 8, so Rob takes the win.

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
