Answer:

k = -5

Step-by-step explanation:

<u>Step 1:  Add 5k to both sides </u>

-5k + 25 + 5k = 40 - 2k + 5k

25 = 40 + 3k

<u>Step 2:  Subtract 40 from both sides </u>

25 - 40 = 40 + 3k - 40

-15 = 3k

<u>Step 3:  Divide both sides by 3 </u>

-15 / 3 = 3k / 3

-5 = k

Answer: k = -5

The expression 2( 21x + 75 ) represents the monthly tuition and the one-time materials fee that Jamie pays for his two children
ss7ja [257]

Answer:  x represents the number of months, 150 represents one-time materials fee,  2( 21x + 75 ) represents total fees in x months and 42 represents rate of change.

Step-by-step explanation:

Since, Here the expression 2( 21x + 75 ) represents the monthly tuition and the one-time materials fee that Jamie pays for his two children to join a science club.

Let, f(x) represents the monthly tuition fee

Therefore, f(x)= 2( 21x + 75 )

⇒f(x)= 42 x +150

Again according to the question, there is a one-time materials fee which must be free from the variable.

Therefore In f(x) , 150 must represent one time material fees.

And, x is variable, and here number of months is a variable.

Thus, x must be denote the number of months.

And, 42 must be denote the fees for 1 month.
