Answer:

Step-by-step explanation:

if 12x= 4(x+5), x equals...

distribute the 4 to the x and

12x = 4x + 20

subtract the 4x on both sides

8x = 20

divide by 8

x = 20/8

simplify

x = 5/2

5/2 = 2.5 so the answer is D

Answer:

Here's what i did

Step-by-step explanation:

The answer is h = 0.4t

A linear function is a function in the form of:

y = mx + b;

where y, x are variables, m is the slope of the line and b is the y intercept.

We can use the data in the table to find the relationship between the time (t) and height (h)

Let us use the format (height, time). Hence from the table, we have the points:

(4, 10), (8, 20), (12, 30) and (16,40). Using any two points, in this case (4, 10) and (16,40), we can apply the formula:

[tex]h-h_1=\frac{h_2-h_1}{t_2-t_1} (t-t_1)\\\\h-4=\frac{16-4}{40-10} (t-10)\\\\h-4=0.4(t-10)\\\\h-4=0.4t-4\\\\h = 0.4t[/tex]

Answer:

∠RQS = 156

Step-by-step explanation:

m∠TQS = 24

∠TQS and ∠RQS are linear pair. Linear pair are two adjacent angles and their sum is 180

∠TQS + ∠RQS = 180

  24 + ∠RQS = 180

         ∠RQS = 180 - 24

        ∠RQS = 156

Answer:

156

Step-by-step explanation:

The angles are a linear pair so that means the sum should add up to 180 degrees.

RQS + YQS = 180

We already know that TQS = 24

RQS + 24 = 180

x + 24 = 180

x = 156

Answer:

He bought 12 books.

Step-by-step explanation:

Here is your equation: 6 b+3=75

Step 1- Subtract 3 from both sides: 6 b+3-3=75-3

6 b=72

Step 2- Divide by 6: 6 b/6=72/6

b = 12 books in total.

Answer:

sample answer:   If you make a table of values, you can see that 4 quarters equal 1 dollar and 8 quarters equal 2 dollars. If you graph the data, you will see a straight line. Therefore, this situation represents a linear function with a constant rate of change of 1/4

Step-by-step explanation:

The situation is a representation of the linear function.

Given that,

One dollar is divided into four quarters.

The total number of dollars is a function of the number of quarters.

Based on the information presented above, we can conclude that when the dollar represents y value and the quarter represents x value

As a result, the slope should be 1/4.

y = 1/4x should be the linear function.

Hence, As a result, we can conclude that the situation is a linear function.

Answer:

1. All of the above.

2. Kilowatt hours.

Step-by-step explanation:

A power bill can be defined as a utility bill issued by a power utility company (provider) to illustrate the amount of energy (electricity) consumed by a customer.

Power bills usually show the following informations;

1. The total amount due: this represents an amount of money being owed by a consumer to a power utility company. The current amount due in addition to any outstanding balance is reflected in this tab.

2. The Kilowatt hours of electricity used: this represents the amount of electricity that was used by the consumer in the previous month.

3. The payment due date: this represents the least expected date for payment to be made by the consumer. If payment isn't made on or before the due date, the consumer will be disconnected.

Generally, when calculating the power bill, power companies use kilowatt hours. The Kilowatt hours (KWh) represents the amount of energy (electricity) that is being used by a customer on a hourly rate.

Answer:

1. All of the above.

2. Kilowatt hours.
3.  $52.36

Answer:

Slope:1

Step-by-step explanation:

When finding the slope from 2 points, you subtract them y/x

(-6,3)

(-4,5)

-2,-2

Slope: (-2,-2)=1

y=x+b

Insert on of the the points, in this case, I will choose -6,3

3=-6+b

b=9

So slope intercept form, the answer will be y=x+9.

Since you are just finding the slope, the answer is just 1.

The slope of the line that contains the points:(-6, 3) and (-4,5) is 1.

You could be asked to determine a line's slope when working with linear equations. Knowing the slope formula in that situation is really helpful. Watch this lesson to learn the formula for calculating the slope of a line.

Given the coordinate of the line (-6, 3) and (-4,5).

Hence from the formula of the slope (m) =  [tex]\frac{y2 - y1}{x2 - x1}[/tex]

m = (5 - 3) / (-4 + 6)

m = 1

Therefore the slope of the line that contains the given points is 1.

We are told that there are 90 males and 75 females.

This question is a greatest common factor question.

We find the factors of 75 and 90

The factors of 75 are: 1, 3, 5, 15, 25, 75

The factors of 90 are: 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90

Then the greatest common factor is 15.

The greatest number of people that can be in each group is 15

Answer:  y=759

Answer:

y = 759

Step-by-step explanation:

subtract the numbers

y = 23 (35 - 2)

y = 23 x 33

Multiply the numbers

y = 759

Solution

y = 759

Step-by-step explanation:

x−7(x−2)=10x+9−x

Step 1: Simplify both sides of the equation.

x−7(x−2)=10x+9−x

x+(−7)(x)+(−7)(−2)=10x+9+−x(Distribute)

x+−7x+14=10x+9+−x

(x+−7x)+(14)=(10x+−x)+(9)(Combine Like Terms)

−6x+14=9x+9

−6x+14=9x+9

Step 2: Subtract 9x from both sides.

−6x+14−9x=9x+9−9x

−15x+14=9

Step 3: Subtract 14 from both sides.

−15x+14−14=9−14

−15x=−5

Step 4: Divide both sides by -15.

−15x−15=−5−15

x=13

Answer:
