Answers

Answer: Inductive Reasoning.

Had to complete the question first.

Maria is writing a list of numbers. She asked Susanne what the next number would be . After looking at the list: 7,14,21,28,35,42,_Susanne states,”the next number will be 49” inductive or deductive.

Step-by-step explanation:

inductive reasoning: This is known as a process of using observations and  examples to reach a conclusion or decision.

When ever a pattern or trend is used to predict the next possible outcome, you are using inductive reasoning. Just like from Maria list Susanne was able to predict that the next number would be 49 because the sequence increases with an interval of 7. ( 7, 14, 21, 28, 35, 42, 49).

Points A, B, and C are collinear. Point B is between A and C. Solve for x if AC = 3x + 3, BC = 3, and AB = 2x + 2.

Answers

Answer:

x=2.

Step-by-step explanation:

It is given that points A, B, and C are collinear. Point B is between A and C.

Using segment addition property, we get

[tex]AC=AB+BC[/tex]

It is given that AC = 3x + 3, BC = 3, and AB = 2x + 2.

[tex]3x+3=(2x+2)+3[/tex]

[tex]3x+3=2x+5[/tex]

Isolate variable terms.

[tex]3x-2x=5-3[/tex]

[tex]x=2[/tex]

Therefore, the value of x is 2.

How do you undo a fraction? I know it's with multiplication, but what do you need to multiply?

Answers

Use the reciprocal
Example: 5/8
To undo times it by 8/5 to get 1

Answer:

by  the opposite of the fraction

Step-by-step explanation:

for example 3/17 would be undone by multiplying it by 17/3 so the 3s cancel eachother out and so do 17 and 17
