Answer:
40$
Step-by-step explanation:
We have the 2 equations
1- ) 5x-8y=6
2-) -6x-3y=18
multiplying the first equation by 3 and the second equation by 8 then subtracting
1-) 15x-24y=18
2-) -48x-24y=144
-48x-24y=144
(-) 15x-24y=18
-------------------------------------
-63x = 126
x=-2
substituting in equation 1
5(-2)-8y=6
-10-8y=6
-8y=16
y=-2
the soultion is (-2,-2)
Answer:
C
Step-by-step explanation:
A central angle is an angle formed at the centre of the circle by 2 radii
∠KOD is at the centre formed by radii OK and OD
central angle is KOD → C
6 is the mode since it appears the most, 3 times
