15:40
= 15/40
= 3:8
An equivalent to 15:40 is 3:8~
Answer:
12
Step-by-step explanation:
(5/3)y-8 = (7/3)y-16
(5/3)y- (7/3)y = 8 -16
(-2/3) y = -8
y = 3*8/2
y=24/2
y=12
Answer: (3.5,-2)
Step-by-step explanation:
To solve this problem, all we have to do is plug in y=-2 into either equations from step one to find the coordinate. To make sure we have the right x-coordinate, let's plug in y for both equations.
4x-7y=28 [plug in y=-2]
4x-7(-2)=28 [multiply]
4x+14=28 [subtract both sides by 14]
4x=14 [divide both sides by 4]
x=3.5
------------------------------------------------------------------------------------------------------------
6x-5y=31 [plug in y=-2]
6x-5(-2)=31 [multiply]
6x+10=31 [subtract both sides by 10]
6x=21 [divide both sides by 6]
x=3.5
Now, we know the solution to the system is (3.5,-2).
The angle measure of one part will be 60.
360/6 = 60
That is because the circle it divided into 6 equal parts and the whole circle is 360.
Hope this helps :)
