Answer 2

Answer:

x can be any real number.

Step-by-step explanation:

- 4 (x - 1) = - 3x + 13 - 9 - x

The easiest approach to solving this problem is to simplify each side. Start by focusing on the left side, distribute the term outside of the parenthesis, multiply every term inside the parenthsis by the term outside of it,

- 4 ( x - 1 ) = - 3x + 13 - 9 - x

Distribute,

(-4)(x) + (-4)(-1) = - 3x + 13 - 9 - x

Simplify,

-4x + 4 = - 3x + 13 - 9 - x

Simplify the right side of the equation, combine like terms,

-4x + 4 = - 3x + 13 - 9 - x

Rearrage,

-4x + 4 = -3x - x + 13 - 9

Simplify,

-4x + 4 = -4x + 4

At this point, one should use inverse operations to solve the problem, but the given equation is an identity, meaning that any real value can be substituted into the parameter (x), and the equation will yield a true result. Thus, (x) equals all real numbers.

Ms. Hendricks encourages her sixth-grade class to keep reading during breaks from school. She said that during a break lasting d days, they should each read 30d minutes in total. This year, spring break is 9 days long.
How many minutes should each student read during spring break?
Write your answer as a whole number or decimal.

Answers

I believe the answer should be 270.

You should replace the “d” in 30d with a nine because the “d” stands for how many days. The question said there are nine days so you would get this...

Mrs. Chevalier’s class is reviewing by playing a math game. Mrs. Chevalier randomly selects an integer from the set of integers -15 to 15.

Part A

What is the probability that Mrs. Chevalier names a positive integer?

Part B

Explain how you determined your answer.

Answers

Answer:

(15/31) ?

Step-by-step explanation:

|-15| = 15

15+15+1 (for 0) = 31

1 through 15 are positive, so 15 of the 31 could be positive, or 15/31

Sorry, could be wrong, but I think it's right

Part A Answer: The probability that Mrs. Chevalier names a positive integer is a 50% chance.

Part B: Numbers from -15 to 15 is thirty-one total numbers including zero, but zero is neither negative nor positive, so it doesn’t really count in this situation unless the instructions describe it as positive. Without the zero, it is thirty numbers in total, with half of them being negative, and half of them being positive, which can also be said as 50%. You can find this answer by dividing 15 by 30, which is 1/2, or 50%.
