Answer:
The lines are perpendicular
Step-by-step explanation:
we know that
If two lines are parallel, then their slopes are equal
If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal to -1)
we have
----> equation A
isolate the variable y
Divide by 7 both sides
The slope of the line A is 
----> equation B
isolate the variable y
Divide by 3 both sides
The slope of the line B is 
Compare the slope of both lines
so
----> the lines are not parallel
Find the product of the slopes
----> the lines are perpendicular
How many men or women are there or else we can't find the answer and like the other person said you have to finish the question
Answer:
Here you go! 8x+10-5x!
Just kidding. here you go. x=1.66
Step-by-step explanation:
you can simplifiy the x´s by making it 3x by subtracting. You can also subract 10 from both sides. That leaves you with 3x=5.
x=1.66
Answer:
6.7%
Step-by-step explanation:
cost: 75 cedis
sale price: 80 cedis
amount of profit: 80 cedis - 75 cedis = 5 cedis
Now we find what percent 5 cedis is of 75 cedis.
percent = part/whole * 100%
percent = 5/75 * 100%
percent = 0.06666 * 100%
percent = 6.6666%
percent = 6.7%
Answer:
B. 30
Step-by-step explanation:
The mosaic tile has a trapezoidal shape, so that its area can be determined as follows;
Area of a trapezium = 
(a + b)h
where: a and b represent the length of its plane sides, and h is the height.
Area of a mosaic tile = (4 + 6) 4
= 10 x 2
Area of a mosaic tile = 20 square inches.
But, Dan wants to cover a 600 square inch area.
So that the number of tiles needed = 
= 30
The number of mosaic tiles needed by Dan is 30.
