Final answer:

To simplify 7(x-4), distribute 7 over x and -4 to get 7x - 28. This is an application of the distributive property in algebra.

Explanation:

To simplify the expression 7(x-4) using the distributive property, you multiply the number outside the parenthesis, which is 7, by each term inside the parenthesis. The distributive property allows us to remove the parentheses by distributing the multiplication over the subtraction within.

Here is the step-by-step simplification:

Multiply 7 by x, which is 7x.

Multiply 7 by -4, which is -28.

Combine the results to get 7x - 28.

Therefore, 7(x-4) simplifies to 7x - 28.

ANSWER

The Multiplicative Property of Equality

EXPLANATION

The Multiplicative Property of Equality allows us to multiply both sides of the given equation by the same quantity.

So for the given equation,

[tex]\frac{x}{5}=2[/tex]

When we multiply both sides by 5, we get;

[tex]5\times \frac{x}{5}=2\times 5[/tex]

[tex]\Rightarrow x=10[/tex]

x/2 + 5 = 10

Subtract 5 from both sides.

x/2 = 5

Multiply both sides by 2.

x = 10 (This is your answer.)

For 2.5% rise we first find increase and then add it to 6

Increase = 2.5% of 6 = 2.5/100 × 6= 15/100 =0.15$

New rates = $(6+0.15) = $6.15

x=a-y

We find this by subtracting a from both sides to find x.

x = y - a

isolate x by subtracting a from both sides of the equation

x = y - a

Answer: 80 miles.

Step-by-step explanation:

1. You have the following information given in the problem above:

- Carter ran 48 miles.

- 48 miles was 60% of Carter's goal.

2. Then, to calculate the number of miles that Carter set at his goal, you need to divide 48 miles by 60 and multiply this by 100, as following:

[tex](\frac{48}{60})(100)=80[/tex]

3. Therefore, the answer is 80 miles.

We know that the perimeter of a rectangle is:

[tex]P=2L+2W[/tex] (1)

Where:

P is the perimeter

L: it's the long

W: is the width

They tell us that the perimeter is:

(4y + 1)

The long is y

The width is y-5.

Then we can write equation (1) as follows:

[tex](4y + 1)=2y+2(y-5)[/tex]

[tex]4y+1=4y-10\\[/tex]

[tex]1 = -10\\[/tex]

The equation can not be solved and, therefore, it is not possible to find the value of "y" with the information provided.

Assuming each movement is in a straight​ line, the composition

represents the moves.

Each movement is in a straight line, the composition represents the moves <-5, 1>, <-3, 4>, <1, 4> and <2, 7>.

Given that, a robot travels from position A to B to C to D.

We need to find what composition of rigid motions represents those moves.

Any way of moving all the points in the plane such that

a) the relative distance between points stays the same and

b) the relative position of the points stays the same.

There are four types of rigid motions that we will consider: translation, rotation, reflection, and glide reflection.

In a translation, everything is moved by the same amount and in the same direction. Every translation has a direction and a distance.

Therefore, each movement is in a straight line, the composition represents the moves <-5, 1>, <-3, 4>, <1, 4> and <2, 7>.

Answer:

Rhonda: 39 hours; Chris: 18 hours.

Step-by-step explanation:

If you subtract the extra 3 hours from the total, you have Chris's hours plus twice Chris's hours adding to 54. That is, Chris worked 54/3 = 18 hours, and Rhonda worked 57-18 = 39 hours = 2·18 +3 hours.

_____

If you insist on equations, you can write two of them:

... r = 2c +3

... r + c = 57

Substitute for r in the second equation:

... (2c +3) +c = 57

... 3c +3 = 57 . . . . . from here down, the explanation above matches this math

... 3c = 54

... c = 54/3 = 18

... r + 18 = 57 . . . . . . substitute for c in the second equation

... r = 57 - 18 = 39

Isolate the f. Note the equal sign. What you do to one side, you do to the other.

First, subtract 6e from both sides

6e (-6e) - 7f = 8g + h (-6e)

-7f = 8g + h - 6e

Divide -7 from both sides

(-7f)/-7 = (8g + h - 6e)/-7

f = -8/7g + h/-7 + 6/7e

f = -8/7g + h/-7 + 6/7e is your answer

Answer:

Normal distribution

Step-by-step explanation:

A normal distribution can be easily identified if you can see a "bell shape/curve" in the plotted bar chart or line chart.

With regard to a Bat chart a normal distribution can be identified when most of the tall bars are in the middle and when going from middle to both left and right you see the height of the bars dropping at the same rate both ways.

I have attached an image by editing your attachment. I have shown the "bell shape/curve" or the normal distribution.

i think the answer is 214 i am not sure but i think it is

The number you are looking for is 211.

To find the number that meets the given criteria, we need to consider a few steps

1. The number, when rounded to the nearest ten, is 210.

2. The sum of the digits of the number is 4.

First, let's consider the numbers that round to 210 when rounded to the nearest ten. These numbers fall within the range of 205 to 214 (inclusive).

Next, let's identify which of these numbers has digits that sum to 4.

- 205: (2 + 0 + 5 = 7)

- 206: (2 + 0 + 6 = 8)

- 207: (2 + 0 + 7 = 9)

- 208: (2 + 0 + 8 = 10)

- 209: (2 + 0 + 9 = 11)

- 210: (2 + 1 + 0 = 3)

- 211: (2 + 1 + 1 = 4)

- 212: (2 + 1 + 2 = 5)

- 213: (2 + 1 + 3 = 6)

- 214: (2 + 1 + 4 = 7)

From this list, the number 211 is the only number within the range that has digits summing to 4.

Answer:

375

Step-by-step explanation:

Did it on Edge

The total distance of the race is 375 miles.

Given data:

To find the total distance of the race, multiply the distance of the loop by the number of times Carlos raced around it.

Total distance = Distance of the loop * Number of times raced

Distance of the loop = 15 miles

Number of times raced = 25

Substituting the values into the formula:

Total distance = 15 miles * 25

On simplifying the equation:

Calculating the product:

Total distance = 375 miles

Hence, the total distance was 375 miles.
