Write an equivalent expression for 7 + 5 k minus 2 minus 3 k + n. Which statements are true about the steps for writing the equivalent expression? Check all that apply.
Combine the constant terms by adding 7 and –2.
The equivalent expression is 9 + 3 k.
n, 5 k, and negative 3 k are like variable terms.
Combine the like variable terms by adding the coefficients.
5 k and negative 3 k are like variable terms.
The constants 7 and –2 are like terms.
The equivalent expression is 5 + 2 k + n.
Combine the constant terms by adding 7 and 2.

Answer:

* 5+2k+n

Step-by-step explanation:

Combine all like terms:

7-2 = 5

5k-3k = 2k

n = n

prove that for any natural value of n the value of the expression (n+2)^2-(n-2)^2 is a multiple of 8.

The rainfall for the month of July was above average. The water level in a small lake measured 8 3/4 feet at the beginning of the month. Due to all the rainfall, the water level rose 3/5 of a foot per week for the first three weeks, then the lake dropped 1/2 foot in the last week of the month.
What was the water level of the lake at the end of July?
A. 7 11/20 ft
B. 9 7/9 ft

A college student is looking for a data plan for her cell phone. She has found an option that offers a 2 gigabyte monthly allowance for data.

The monthly cost of this plan can be represented by function C, defined by:

C(x) = 30x + 5, where x is the gigabyte of data used over the monthly allowance.

Find C(0.7)

Select the correct answer as well as the correct explanation for the situation.
Group of answer choices
A. C(0.7)= 26 This means the plan costs $26 a month.
B.vC(0.7)= 26 This means that the cost would be $26 if she uses 0.7 gigabytes over the 2 gigabytes allowance in a month.
C. C(0.7) = 50 This means that the cost would be $50 if she goes over the 2 gigabytes monthly allowance.

A. 67x - 1,526 < 2,016
B.67x < 1,526
C.67x + 1,526 < 2,016
