Answer:

7

Step-by-step explanation:

2x+34=4(x+5)

2x+34=4x+20

-2x=-14

x=7

Answer:

x=7

Step-by-step explanation:

The formula 2(7x+3) can be translated into 14x +6 using the distributive property of multiplication over addition (Option B).

The expression 2(7x+3) is equivalent to the expression 14x+6. Such mathematical expressions are related to the concepts of algebra, specifically, the distributive property of multiplication over addition. This property allows the distribution of 2 over the terms inside the parentheses, 7x and 3 in this case. When we multiply 2 by 7, we get a result of 14, and when we multiply it by 3, we get a result of 6. So, option B: 14x + 6 is the correct response to this question.

Answer:

Red : 5/12

Blue : 1/3

Green: 1/6

Yellow : 1/12

Step-by-step explanation:

5 red marbles + 4 blue marbles + 2 green marbles + 1 yellow marble = 12 total marbles

5 red marbles / 12 total marbles = 5/12

4 blue marbles / 12 total marbles = 4/12 = 1/3

2 green marbles / 12 total marbles = 2/12 = 1/6

1 yellow  marbles / 12 total marbles = 1/12

It would be 925 inches cubed.

To find the volume, know that to find the volume of any rectangular prism (which is what this is) is to do Length * Width * Height to get the volume.

By doing, 18.5 * 12.5 * 4, you'll get your answer.

18.5 * 12.5 * 4 ---> 925

Remember to make in the unit of inches (because that's the unit it was asked in) and to write cubed at the end (since you are finding the area of a 3d object).

Answer:

125.60

Step-by-step explanation:

the formula for the area of a cylinder is A=2πRH+2πRsquared. I find it easiest to multiply pi by 2 instead of anything else which is 6.28. Then I multiply the radius (2) times the height (8) equaling 16. Then you multiply that number by 6.28. Equaling 100.48. Then you have to do the second part which is radius (2) squared equaling 4. Then you multiply that by 6.28, equaling 25.12. then you add the two sums (25.12+100.48=125.60).

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

Given:

A table of values of a linear function.

To find:

The slope, y-intercept and equation of the function.

Solution:

Take any two points on the table.

Let the points are (-1, -3) and (0, -6).

Slope of the line:

[tex]$m=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]$m=\frac{-6-(-3)}{0-(-1)}[/tex]

[tex]$m=\frac{-6+3}{0+1}[/tex]

[tex]$m=\frac{-3}{1}[/tex]

m = -3

Slope of the function = -3

y-intercept of the function is the point where x = 0.

In the table y = -6 when x = 0

y-intercept = -6

Equation of a line:

y = mx + c

where m is the slope and c is the y-intercept

y = -3x + (-6)

y = -3x - 6

Equation of a function is y = -3x - 6.

The slope of the function's graph is 3, the y-intercept is 2, and the equation for the function is y = 3x + 2.

To find the slope of the function's graph, we can use the formula: slope = (change in y) / (change in x). We can choose any two points from the table and calculate the slope. Let's choose the points (0,2) and (1,5). The change in y is 5 - 2 = 3, and the change in x is 1 - 0 = 1. Therefore, the slope is 3/1 = 3.

To find the y-intercept of the function's graph, we can use one of the points from the table. Let's use the point (0,2). Since the y-intercept is the value of y when x = 0, the y-intercept is 2.

The equation for a linear function is y = mx + b, where m is the slope and b is the y-intercept. So for this function, the equation is y = 3x + 2.

Answer: x = 40

Step-by-step explanation: I know that it's tempting to try to do percentage word problems in your head but this leads to a variety of careless mistakes. So I would advise always writing out the equation by simply reading the problem from left to right and solving it from there. That way you don't have to think about the problem at all until you get to your final answer.

So for this problem we have what percent. Since we know that percent means over 100 and what means x,

what percent would be x/100.

Of means times, 36 is 36, is means equals, and 81 is 81.

So we have the equation x/100 · 20 = 8.

We can rewrite this problem as 20x/100 = 8.

To get rid of the fraction, we multiply

both sides by 100 and we have 20x = 800.

Dividing both sides by 20, you can use a

calculator to find that that x = 40.

Now let's check to see if our answer makes sense.

We have 40% of 20 is 8.

Well we know that 100% of 20 would be 20. So 40% of 20 should be alot less than 20 so 8 seems to make sense.

I have attached my own work in the image provided.

Final answer:

To determine what percent of 20 is 8, you divide 8 by 20 and multiply by 100, which equals 40%. Thus, 8 is 40% of 20.

Explanation:

To find out what percent of 20 is 8, we use the formula for percentage which is
(Part/Whole) × 100. In this case, 8 is the part (the number we're trying to find the percentage for) and 20 is the whole (the reference number we're comparing to). So, we calculate (8/20) × 100 to get the percent.

Step-by-step calculation:

Divide 8 by 20 which equals 0.4.

Multiply 0.4 by 100 to convert it to a percent.

0.4 × 100 equals 40%.

Therefore, 8 is 40% of 20.

Answer:

80% or 4/5

Step-by-step explanation:

There are five numbers and four of the numbers are positive which means you'll have 4 out of 5 chance getting a positive number, which is equivalent to 80%

Answer:

$5000

Step-by-step explanation:

To get the amount earned as commission, we deduct the fixed pay from the total earned pay. Given the total monthly earnings as $2400 while fixed pay of $2200, in this case, the amount of commission will be

Commission= 2400-2200=200

Since the commission is 4% of the total sales, then the total sales equivalent to 100% is given by cross multiplication

If4%=$200

100%=?

Total sales will be 100%*$200/4%=$5000

Therefore:

A=10*[(8+12)/2]

A=10*(20/2)

A=10*10

A=100

So the area of the trapezoid is 100 m^2

Step-by-step explanation:

Similarity in Mathematics refers to two shapes resembling each other such that one can be acquired from the other using a sequence of dilations and rigid transformations. They have the same angle measures and proportional side lengths.

In the field of Mathematics, particularly in Geometry, similarity refers to the concept that alludes to how well two shapes resemble each other. Two shapes are considered similar if you can obtain one from the other using a sequence of stretches, shrinks (know as dilations), and rigid transformations (like rotation, reflection, or translation).

In other words, option D is the most accurate: If there is a sequence of rigid transformations and dilations, that take one figure to the other, then they are similar. It's important to note that the characteristics of similar figures include having the same angle measures and proportional side lengths.

Answer: 12x/20

Step-by-step explanation:

Looking at 3x/5

The expression equivalent is 12x/20

The reason is this

12x/20

If you divide the 12x by 4

It will give you 3x

If you divide 20 by 4

It will give you 5

Therefore, you will still have 3x/5

Another way to look at it is this

3x/5= 0.6x

12x/20= 0.6x

Therefore, the final answer is b which is 12x/20

Answer:

D. -2/3

Step-by-step explanation:

Since it is going down, it is negative

Think of this: Rise/Run

In this case, rise is when you are going up or down the graph

Run is when you are going to the right of the graph

Let's use 2 points (0,3) and (3,1)

Since you are going three points to the right we are going to put 3 in for run

You are going 2 places down, so we are going put -2 in for rise

This gives us -2/3

Another way to do this is (1-3)/(3-0) = -2/3
