4(m + 3 + 5m)

Part A: Write two expressions that are equivalent to the given expression. (3 points)

Part B: Show that one of your expressions in Part A is equivalent to the given expression using algebraic properties. Explain which properties you used. (4 points)

Part C: Show that your other expression from Part A is equivalent to the given expression by substituting a number for m. (3 points)

Answers

Answer:

See below.

Step-by-step explanation:

Part A:

4(m + 3 + 5m) =

= 4m + 12 + 20m

4(m + 3 + 5m) =

= 4(6m + 3)

Part B:

Use the distributive property on the given expression to get the first expression.

4(m + 3 + 5m) =

= 4 * m + 4 * 3 + 4 * 5m

= 4m + 12 + 20m

Part C:

Let m = 2

a. Substitute 2 for m in the original expression:

4(m + 3 + 5m) =

= 4(2 + 3 + 5 * 2)

= 4(5 + 10)

= 4(15)

= 60

b. Substitute 2 for m in the second equivalent expression of part A.

4(6m + 3) =

= 4(6 * 2 + 3)

= 4(12 + 3)

= 4(15)

= 60

By substituting 2 for m, both expressions evaluate to 60.

Part A: 24m+12, 12(m+2)

Make a histogram for drivers' ages using the data from the table below.

Driver’s Ages
Age Frequency
17-19 8
20-22 7
23-25 9
26-28 4


Answers

It should be like this since each column has to go up to the frequency number.. pretty simple

The histogram shows the distribution of the age and the frequencies

How to plot the histogram?

The dataset is given as:

Age    Frequency

17-19       8

20-22     7

23-25     9

26-28     4

The age would be plotted on the x-axis, while their frequencies on the y-axis.

So, we have:

x            y

17-19       8

20-22     7

23-25     9

26-28     4

What is the definition of a four-dimensional (4-D) shape?

Answers

A four-dimensional space or 4D space is a mathematical extension of the concept of three-dimensional or 3D space. Three-dimensional space is the simplest possible generalization of the observation that only three numbers, called dimensions, are needed to describe the size or position of objects in the everyday world. For example, the volume of a rectangular box is found by measuring its length (usually labeled x), width (y), and depth (z).

Mrs. Greensmith works a PC Richards and earns $35 per week plus a 12% commission o sales. How much would she earn for the week if her sales for the week was $1,750?

Answers

answer: $245

she makes $35 every week (her wage, i’m assuming) regardless of how many sales she makes.

in order to find out how much money she makes out of her sales, you have to multiply the percentage commission by how much her sales was: so .12x1750 = $210 from sales.

you then add up her wage and her sales money, so $35 from wage + $210 from sales = $245 total for the week

answer: $245

The end of the passage is in the Picture that I Posted so make sure you read it). Passage: Excerpt from "A Cooking Revolution:How Clean Energy and Cookstoves Are Saving Lives" by Chef Jose Andres, June 7, 2016.) Cooking: it's a simple act that has brought families around the world together for thousands of years. As a chef, I can think of few things more beautiful than that. However, I also know how deadly such a simple act can be, not only to our health, but to our environment. Think about it: For Americans, turning on the stove means simply turning a knob or switch. For people living in developing countries, particularly women and childern, it means hours of collecting fuels like firewood, dung, or coal to burn in a rudimentary, smoky cookstove or over an open fire. The result is a constant source of toxic smoke that families breathe in daily causing diseases like child pneumonia, heart disease, and lung cancer, not to mention taking a child away from her education. In fact, diseases caused by smoke from open fires and stoves claim 4.3 million lives every year. That's more than AIDS , malaria. and tuberculosis combined. And the environment suffers, too. When people collect wood every day from their local forests to create charcoal or fuel for wood - burning stoves, it creates an unsustainable pace of deforestation that leads to mudslides, loss of watershed, and other environmental consequences. These stoves also contribute up to 25 percent of black carbon emissions, a pollutant that contributes directly to climate change. You see, from what we cook to how we cook, our foods connects with our lives on so many levels. That's why having access to better technology and clean energy for cooking is as equally important as the ingredients in the food being prepared. It's also why I'm proud to support an effort to bring clean cookstoves and fuels to millions of people in developing countries. ( Question 1: Read this paragraph from the excerpt: And the environment suffers, too. When people collect wood every day from their local forests to create charcoal or fuel for wood - burning stoves. it creates an unsustainable pace of deforestation that leads to mudslides, loss of watershed, and other environmental consequences. These stoves also contribute up to 25 percent of black carbon emissions, a pollutant that contributes directly to climate change. " Why does the author place this paragraph immediately after the two paragraphs about diseases?) A) This paragraph makes a point that contrasts with the point of the previous two paragraphs. B) This paragraph is less important than the previous ones. so it is placed later in the order. C) This paragraph continues the previous two paragraphs by providing evidence for their idea. D) This paragraph makes a related but broader point about environmental harm rather than harm to individuals. ( Question 2) What is the effect of this quote on the tone of the passage? I'm proud to support an effort to bring clean cookstoves and fuels to millions of people. A) It contributes to a somber tone. B) It contributes to a lighthearted tone. C) It contributes to a passionate tone. D) It contributes to a factual tone. ( Question 3) Read these paragraphs from the excerpt: Cooking: it's a simple act that has brought families around the world together for thousands and thousands of years. As a chef, I can thinknof a few things more beautiful than that. However, I also know how deadly such a simple act can be, not only to our health, but to our environmental. Think about it: For Americans , turning on the stove means simply turning a knob or switch. For people living in developing countries, particularly women and childern, it means hours of collecting fuels like firewood, dung, or coal to burn in a rudimentary, smoky cookstove or over an open fire. ( How do these paragraphs contribute to the development of the author's argument?) A) They establish the author's excerpt knowledge about cooking, which demonstrates he is an authority on inferior cookstoves. B) They provide personal support for the global solution to the problems of cooking that the author presents in the article. C) They introduce the solution to the negative effects of cooking in the developing world that appears in later paragraphs. D) They stress that Americans take for granted the ease of cooking in the United States so they may be unsympathetic about this issue. Will Mark Brainliest.
