–3(t − 17) = 6 whats the answer

Answers

Answer:

t = 15

–3(t − 17) = 6

Step-by-step explanation:

1. Distribute the –3 to the terms inside the parentheses:

–3 * t + 3 * 17 = 6

2. Simplify:

–3t + 51 = 6

3. Next, we want to isolate the variable t by getting rid of the constant term. To do this, we can subtract 51 from both sides of the equation:

–3t + 51 - 51 = 6 - 51

This simplifies to:

–3t = -45

4. Now, to solve for t, we need to isolate the variable. Since –3t means –3 times t, we can divide both sides of the equation by –3:

–3t / –3 = -45 / –3

This simplifies to:

t = 15

So, the solution to the equation –3(t − 17) = 6 is t = 15.

Answer:B

Step-by-step explanation:

Maria is comparing the prices of two window cleaning companies. Company A charges $6 per window and an additional $12 as service charges. Company B charges $5 per window and an additional $15 as service charges.Part A: Write equations to represent Company A's and Company B's total charges for cleaning a certain number of windows. Define the variable used in the equations. (4 points)

Part B: Which company would charge less for cleaning 8 windows? Justify your answer. (3 points)

Part C: How much money is saved by using the services of Company B instead of Company A to clean 6 windows? (3 points)

Answers

Part A
y=6x+12
y=5x+15
x is the amount of windows, y is the total amount of money 
Part B
y=6(8)+12       =60
y=5(8)+15      =52
Company B 
Part C
y=6(6)+12       =48
y=5(6)+12       =42
$6 is saved
