Can someone answer q3

Answers

Answer 1

Answer:

Step-by-step explanation:

$(2x + 5)/(4) = 9x - 11$

2x + 5 = 4(9x - 11)

2x + 5 = 36x - 44

36x - 44 = 2x + 5

36x - 2x = 5 + 44

34x = 49

x = 49/34

Answer 2

Answer:

Answer:

x=49/34

Step-by-step explanation:

1.) Multiply both sides by 4

(4) 2x+5/4 = 9x-11 (4)

2x+5 = 36x-44

2.) Subtract 2x from both sides

2x+5 = 36x-44

-2 -2

5 = 34x-44

3.) Add 44 to both sides

5 = 34x-44

+44 +44

49=34x

4.) Divide by 34

49/34 = 34x/34

x=49/34

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) (10 points)

Answers

Answer:

Part A:

Let 'x' be the number of windows cleaned.

Let 'y' be the total cost of cleaning 'x' windows.

Company A charges $6 per window and an additional $12 as service charges. So equation becomes $y=6x+12$

Company B charges $5 per window and an additional $15 as service charges. So equation becomes $y=5x+15$

Part B :

Cost for cleaning 8 windows.

Company A = $y=6(8)+12$ =$60

Company B = $y=5(8)+15$ =$55

Company B charges less for 8 windows.

Part C:

Cost for cleaning 6 windows.

Company A = $y=6(6)+12$ =$48

Company B = $y=5(6)+15$ =$45

Money saved by using company B is $48-45=3$ dollars.

Part A Answer: Company A: (Wx6)+12 Company B: (Wx5)+15The varible used was W because windows start with a W i chose this as the variable because it is for the certain NUMBER of windows.Part B:Company A: 8x6=48+12=$70 for 8 windows and service charges.Company B:8x5=40+15=$55 for 8 windows and service charges.Company B would charge less for 8 windows.Part C:My work for Company A: 6x6=36+12=$48 for 6 windows and service chargesMy work for Company B: 6x5=30+15=$45 for 6 windows + service charges$48-$45=$3Answer for Part C: $3 would be saved by using the services of Company B instead if Company A to clean 6 windows.

Simplify the fraction 4t2-16/8/t-2/6

Answers

The first thing we are going to do in this case is to rewrite the expression:
4 (t2-4) / 8 / t-2/6
4 (t-2) (t + 2) / 8 / t-2/6
We now use the double C:
24 (t-2) (t + 2) / 8 * (t-2)
We simplify similar terms:
24 (t + 2) / 8
3 (t + 2)
Answer:
The simplified expression is:
3 (t + 2)
