Substitute w = 1 and w = 3 to determine if the two expressions are equivalent.

4 (3 w + 4) 16 w + 12

Which statements are true? Check all that apply.
A The value of both expressions when w = 1 is 28.
B The two expressions are equivalent.
C The value of both expressions when w = 1 is 16.
D The two expressions are not equivalent.
E The value of both expressions when w = 3 is 52.
F The value of both expressions when w = 3 is 60.

Answers

Answer:

The true statements are A and D

Step-by-step explanation:

4 (3(3) + 4) is 52, while 16(3) + 12 is 60

that would not be equivalent in w = 3 but it would in w = 1

For this question I would say the answer would be A and D.

We want to solve the following system of equations using the substitution method.
Equation 1- 4p+7q=92/5
Equation 2- 12p+35q=72
Solve for q

Answers

Ok, so you are given the value of P=q+2

The substitution method tells us that we must insert the value we know, into the second equation, 4P+3q= -27

Doing so will give us 4(q+2)+3q= -27

For right now, lets just focus on the first part, 4(q+2)

We can simplify this by distributing(multiplying) the 4 to whats inside the variables.

This will give us 4q+8

now lets add this back to the rest of the equation >>>  4q+8+3q = -27

We can further simplify by adding like terms >>> 7q+8 = -27

subtract the 8 from both sides >>> 7q = -35

now divide both sides by 7 >>> q = -35/7

Therefor q = -5

EDIT*

now that we know q = -5 we can put q into the equation for P !

we know that p=q+2

so lets put q in now >>> p=(-5)+2

and simplify>>> p = -3

I hope this helps:)

It’s -5 when you do the math

You will prepare six questionstwo on each topic. Your two questions for each topic should be related to one another.

Your questions will be based on the reading passages from these lessons:What Is Body Image?Your Own Healthy StyleThe Teen Brain: Still Under ConstructionUnderstanding the Benefits and Risks of Screen Time for AdolescentsScreen Time Guidelines for TeensYour questions should be formed so that they can be answered by understanding all the important concepts in the reading passages. Your questions should be open-ended, allowing the speaker to give longer, more considered and reflective answers. Dont ask questions that are close-ended or that have answers that are too specific or related to factual details of the reading passages. Questions that can be answered with a simple yes or no should be avoided.Note that your questions will be evaluated based on Webbs Depth of Knowledge (DOK). DOK is a unit that measures the level of thinking required to answer a particular question. The DOK measure has four levels:DOK 1These close-ended questions have only one correct answer. They are also known as recall questions because they ask for a simple recall of information, such as facts, figures, or definitions.DOK 2These questions test your understanding of skills and concepts. To answer this type of question, you must compare and contrast, convert information from one form to another, classify and sort, or give explanations.DOK 3These questions test strategic or higher-level thinking in the short term. You may be required to go beyond the text and apply your understanding of one subject area to a question that relates to another subject area. You must generalize, connect ideas, and make inferences in order to answer these questions.DOK 4These questions test strategic or higher-level thinking in the long term. They are extended activitieslike term papers or projectsthat require the application of skills and concepts to solve larger problems. Over the course of the activity, you may be expected to apply skills, manage, adapt, plan, and even propose a course of action to solve a problem.Your questions must be DOK level 2 or 3. Learn more about these DOKs.Here are some resources you can consult when you draft your questions:Interviewing "Experts"Asking the Right QuestionsCreating Good Interview and Survey QuestionsHere are some additional tips to consider when writing your questions:Ask open-ended questions. For example instead of asking, Can we change body images? you can ask, What can we do to promote positive body images? The first question can be answered yes or no. The second question allows the speaker to give a more measured and well-thought-out response.Ask questions that are related to one another on a given topic. You can also ask follow-up questions. For instance, you might ask, How do changes in the teenage brain make teens more vulnerable to addictions such as alcohol? Then you could ask a follow-up question to gain more information: How would a history of drinking in a family affect a teenagers brain structure?Dont ask biased or leading questions that force the speaker to agree with you and answer in a way that suits you.
