Answer:

The constant in the expression is 12

Step-by-step explanation:

The constant of the expression is the value that is independent of the number of minutes Janelle uses. The expression can  be written as :

f(m)=0.05m +12

Example if m is 1 or 2

f(1) = 0.05(1) +12 = 12.05

f(2= = 0.05*2 +12 =0.1 +12 = 12.1

The value 12 is the minimum price of the bill indepent of the consumption of minutes of Janelle. She will always be charged this value.

If QRST below is a rectangle, find x if angle S is equal to 7x + 55.
bazaltina [42]
Because QRST is a rectangle, that means all of the angles must be a right angle, which are 90 degrees. Using this information, solve the expression by creating an equation that lets angle S = 90.

90 = 7x + 55
35 = 7x
x = 5

Tems11 [23]

Answer:

The second equation can be written by equation (1) is given below

8x-5y=3

The two equations represents the same line and therefore they have an infinite number of solutions that are true for both equations.

Step-by-step explanation:

Given equation is 40x-25y=15\hfill (1)

To find the second equation to create the given system of equations to have infinitely many solutions :

The second equation can be written by equation (1) is given below

Tom's real estate office reports that the office's income last month was $315,600, while expenses were $19,567.20. What percent
nordsb [41]

Answer:

<u>6.2% of last month's income was spent on office expenses</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Office's income last month = $ 315,600

Expenses last month = $ 19,567.20

2. What percent of last month's income was spent on office expenses?

To calculate this percent, we use this fraction:

Expenses last month/Office's income last month

Replacing with the real values:

19,567.20/315,600 = 6.2%

<u>6.2% of last month's income was spent on office expenses</u>
