Answer: A

Step-by-step explanation:

I had this question on my test yesterday lol

The system of equation will be ". a + c = 90 8a + 5c = 525"

Let the number of adults tickets be represented by a

Let the number of children tickets be represented by c.

Since 90 total tickets were sold, this can be represented by the equation:

a + c = 90

Since adult movie tickets cost $8 each while the children pay $5 for a ticket, and total cost spent is $525, this will be:

8a + 5c = 525

Therefore, the correct option is A.

I can't answer the question without the example provided, but here are some steps to solve it.

Basic info-

Circumference (C)

3.14 is used for pi π= 3.14

The line halfway of the circle is the radius(r)

The line through the circle is the diameter(d)

Formulas:

C= 2πr

2 × 3.14 × the radius

OR

C= πd

3.14 × the diameter

Answer:

x = 17

Step-by-step explanation:

Here, we want to find the value of x

mathematically, the mean is the sum of the numbers divided by the count of the numbers

The count of the numbers is 5

So we have;

(16 + 14 + x + 23 + 20)/5 = 18

73 + x = 5(18)

73 + x = 90

x = 90-73

x = 17

1.) 510 miles

Take the values you have been given which is 153 miles and 3 gallons of gas

Now divide 153 by 3 to find put the Miles per gallon (MPG)

153/3=51

now take 51 and multiply it by 10

51x10=510

2.) $16 per yard of plywood

Answer:

$27.00

Step-by-step explanation:

First, 10% of 30 = 3.

Second, 30 - 3 = 27

Hope this helps!

Step-by-step explanation:

x + 3 = 0

x = - 3

f(x) = 2x³ - 4x² - 28x + 6

f(- 3) = 2(- 3)³ - 4(- 3)² - 28 x (- 3) + 6

= 2 x (- 27) - (4 x 9) + 84 + 6

= - 54 - 36 + 90

= - 90 + 90

= 0

Therefore,

x + 3 is factor of 2x³ - 4x² - 28x + 6

Answer:

Option b) total number of miles for the trip .

maybe this was your answer

The value of x is equal to 8.

Given the following equation;

[tex]x + y = 12[/tex]  .....equation 1

[tex]x = 2y[/tex]       .....equation 2

To find the value of x, we would solve the system of equations by using the substitution method to determine the value of y;

Substituting eqn 2 into eqn 1, we have;

[tex]2y + y = 12[/tex]

[tex]3y = 12\\\\y = \frac{12}{3}[/tex]

y = 4

Next, we would solve for the value of x;

From equation 2;

[tex]x = 2y\\\\x = 2(4)[/tex]

x = 8

Therefore, the value of x is equal to 8.

Answer:

Step-by-step explanation:

4). This is an exponential function.

5). Let the equation of this function is,

    f(x) = a(b)ˣ

    Since, two points (-1, 4) and (0, 6) are lying on the graph of the function,

    For (-1, 4),

    4 = a(b)⁻¹

    4 = [tex]\frac{a}{b}[/tex] --------(1)

    For (0, 6),

    6 = a(b)⁰

    a = 6

    From equation (1),

    4 = [tex]\frac{6}{b}[/tex]

    b = [tex]\frac{6}{4}[/tex] = 1.5

    Therefore, equation of the function will be,

    f(x) = 6(1.5)ˣ

6). Now the value of f(-4) will be,

    f(-4) = 6(1.5)⁻⁴

           = 1.185

Answer:

$330,000

Step-by-step explanation:

The selling price per unit is $15

The variable cost per unit is $5

Units sold is $33,000

The contribution margin can be calculated as follows

(15-5)×33000

= 10 × 33000

= 330,000

Hence the contribution margin is $330,000
