Which of the equations shown have infinitely many solutions?Select all that apply.
A 3x - 1 = 3x + 1
® 2x - 1 = 1 - 2x
© 3x - 2 =2x-3
D 3(x - 1) = 3x - 3​

Answers

Answer 1
Answer: The answer is D because if you distribute, you get: 3x-3=3x-3
And anything you plug in for X has the same solution on both sides of the equation
Answer 2
Answer:

Answer:

D

Step-by-step explanation:

In order to have infinitely many solutions, the lines must be the same.

If we solve D by using the distributive property, we end up withe 3x-3=3x-3.

3x-3 and 3x-3 are the same lines and intersect infinitely many times, therefore the correct answer is D.

A test has 100 questions. Cora got 85 questions correct. What decimal shows the part of the test she answered correctly? What decimal shows the part of the test she answered incorrectly?model the decimals below.

Answers

Cora got 85% of it correct so the decimal form would be 0.85
85/100 would be what she got CORRECT, and then 15/100 would be what she got INCORRECT. You can easily make them both decimals, because it is over 100, into .85 (the amount she got correct) and .15 (the amount she got incorrect).
