An equation is shown below:

8(2x − 14) + 13 = 4x − 27

Part A: Write the steps you will use to solve the equation, and explain each step. (6 points)

Part B: What value of x makes the equation true? (4 points)

Explain the parts please and i will give brainliest the best best explained one.

Answers

Answer:

x = 6

Step-by-step explanation:

8(2x − 14) + 13 = 4x − 27

solve everything in parentheses

16x - 112 + 13 = 4x - 27

subtract 4x from each side of the equation

16x - 4x - 112 + 13 = 4x - 27 - 4x

reduce

12x - 112 + 13 = -27

combine those known numbers

12x - 99 = -27

add 99 tooth sides of the equation

12x - 99 + 99 = -27 + 99

reduce

12x = 72

divide both sides by 12

12x / 12 = 72 / 12

reduce

x = 6

Answer:

  5 miles

Step-by-step explanation:

Time/speed/distance problems can be worked a number of ways. Here, we want to know the distance walked. We know the total time and the total distance and the two different speeds. So, we can use a variable to represent the value we want to know: w = distance walked (in miles).

The total time is 9:00 -6:50 = 2:10 = 2 1/6 hours = 13/6 hours.

The total time is the sum of times for the two parts of the trip: walking and riding.

  walking time = walking distance/walking speed

  = w/3

  riding time = riding distance/riding speed

  = (20-w)/30

The total time is that given above:

  w/3 +(20-w)/30 = 13/6

  10w +(20 -w) = 65 . . . . . . . . multiply by 30

  9w = 45 . . . . . . . . . . . . subtract 20, collect terms

  w = 5 . . . . . . . . . . . divide by 9

In two or more complete sentences write and solve an inequality for this situation. Explain how you would solve this inequality.

Answers

Answer:

0.5p < 6.50

p < 13

Step-by-step explanation:

The inequality would be p < 13. Since Madison can't spend more than 6.50, the cost of potatoes would need to be less than 6.50. To solve the inequality, you would have to divide both sides by 0.5, giving you p < 13.

Answer:

Madison can buy 13 pounds of patatoes.

Step-by-step explanation:

You have to divide 6.50 by 0.50, but in order to do that you have to move the decimal on both sides two times to the right then you can divide. Then to double check you muliply 13 by 50.

The multiplication of 8x and x is 8x^2.

When we have to do multiplication,

We have given 8x and x.

What is the meaning of multiplication?

Multiplication is defined as calculating the result of repeated additions of two numbers.

you would count how many x's there are and

Raise the x to the power of the number of x's.

and that is

Answers

Answer:

A

Step-by-step explanation:

To move something up or down, it means we're moving along the y-axis. So we need to change the y-coordinate.

To move it up, we'll be moving towards the positive end of the y-axis. On a coordinate plane, if you move anything "up," you're moving closer to the positive end of the y-axis.

To move it five units up, we need to move 5 units positively.

So our y is:

y + 5

To move something left or right, it means we're moving it along the x-axis. So we need to change the x-coordinate.

To move it left, we'll be moving it towards the negative end of the x-axis. Think about it: on a basic number line (which is what the x-axis is), the more you move towards the left, you move closer to 0, and therefore the negative end.

To move it 2 units left, we need to move 2 units negatively.

So our x is:

x - 2

Putting them together, we have:

(x, y)

(x - 2, y + 5)

PLS HELP GIVING BRAINLESS TO FIRST PERSON PLS HELP Sand Dunes Sand dunes are an important part of our environment, but they can also be very harmful. Sand dunes are constantly moving, with help from the wind. If the wind blows hard enough, it can kick up the sand. This leads to dust storms, which are dangerous for all who live near the dunes. Sand also damages buildings that can be centuries old. For example, sand threatens buildings in Egypt, including the pyramids. The sand can break down the stones that made the pyramids. Though there are easy ways to keep sand dunes from moving, not all are good for the environment. For years, oil has been used to stop sand dunes from moving. People drench the sand dunes with oil, and the sand no longer is picked up by the wind. This is not good for the animals living in and around the dunes. It also wastes an important resource. One way of safely keeping the dunes from moving as quickly is to plant trees and other plants along them. These plants keep the dunes from moving when placed at the bottom of the dunes. The dunes stay in place and keep the animals living in the dunes safe. Scientists are also working on the best design possible for sand fences. These would keep the dunes in place and let the animals continue to live there.4Paragraph 2 uses A. cause and effect organization. B. chronological order organization.
