2.3 x 10^3 + 6.9 x 10^3
Add 2.3 to 6.9:
2.3 + 6.9 = 9.2
Because both numbers are x 10^3, that would stay the same.
The answer is 9.2 x 10^3
Answer:
(-8, 2)
Step-by-step explanation:
The question is asking to compute on how many hours will it take them to paint the room and base on the question and the given data in the problem, I would say that the answer would be 1/7+1/6 = 1/x, 6.5 hours. I hope you are satisfied with my answer and feel free to ask for more
Answer:
No solution
Step-by-step explanation:
we have
-----> equation C
-----> equation D
Comparing equation C and equation D
The two lines are parallel because the slope is equal ( m=2)
The y-intercept are different
so
The lines are different parallel lines
therefore
The system of equations has no solution

Answer:
Option (b) is correct.
4x + 6y < 120 inequalities that can be paired with x + y ≥ 20 to create a system that represents the given situation.
Step-by-step explanation:
Given: A small rug requires 4 hours for dyeing and a medium-size rug requires 6 hours for dyeing. The dyers have to make at least 20 rugs, and they must do it in less than 120 hours.
We have write an inequalities that can be paired with x + y ≥ 20 to create a system that represents the given situation and choose the correct option from given options.
Let x represents the small rugs and y represents the medium rugs.
Also, x + y ≥ 20 represents the dyers have to make at least 20 rugs.
And it is given that a small rug requires 4 hours for dyeing and a medium-size rug requires 6 hours for dyeing and that they must do it in less than 120 hours.
So, time taken to dye x small rugs = 4x
also, time taken to dye y medium rugs = 6y
And they have maximum of 120 hours.
So this inequality is represented by 4x + 6y < 120
The answer is: 4x + 6y < 120
