Answer:
x=4,y=3
Step-by-step explanation:
x=19-5y if we transpose equation 2 for x.
Plug that into equation 1
4(19-5y)+3y=25
76-20y+3y=25
76-25=17y
51=17y
y=3
Plug y=3 into equation 2
x+5(3)=19
x=19-15=4
Answer:
(2,0)
Step-by-step explanation:
Take the average of the two x-coordinates: (10-6)/2 = 2
Take the average of the two y-coordinates: (4+(-4))/2 = 0
Midpoint: (2,0)
Answer:
The least common denominator is 6.
Step-by-step explanation:
Answer:
angle 3 + angle 5 = 180°( co-interior angles)
120°+6x=180°
6x=60°
x=10°
therefore, angle 5= 6x=6×10°=60°
