Answer:
<h3>A. 1 hour</h3>
Step-by-step explanation:
If one cleaning company's cost can be calculated by the expression 75 + 50x, where x is the amount of hours they spend cleaning and another cleaning company's cost can be calculated using the expression 50 + 75x, then to calculate how long each company will have to clean to cost the same amount, we will equate both expression of the company cost and solve for x as shown;
On equating:
75 + 50x, = 75x + 50
collect like terms'
50x-75x = 50-75
-25x = -25
divide both sides by -25
-25x/-25 = -25/-25
x = 1
hence the number of hours each company will have to clean to cost the same amount is 1 hour
Answer:12√(3)
Step-by-step explanation:
2√(108)
2 x √(108)
2 x √(36 x 3)
2 x √(36) x √(3)
2 x 6 x √(3)
12 x √(3)
12√(3)
Answer:
D
Step-by-step explanation:
Just multiple them and see which one fits the question.
A: 10 * 8 = 80 * 9 = 720 So it's too big.
B: 9 * 9 = 81 * 9 = 729. Also too big.
C: 9 * 10 = 90 * 9 = 810 too big.
D: 8 * 8 = 64 * 11= 704
To find the final cost you multiply 35.80 x .07 and you get 2.506 but since its money you round it to $2.51. $2.51 is your sales tax and now you need to add it to the cost of the shirt so 35.80+2.51= $38.31
