Answer:
x=2.7142 y=-2.8571,
Step-by-step explanation:
given 4x-8y=12............(1)
14+2x=-6y
2x+6y=-14..........(2)
from equ (2) multiply by 2
4x+12y=-28............(3)
substruct (1) and (3)
4x-8y-4x-6y=12-(-28)
-14y=40 ,y=
=-2.8571
y=-2.8571 put in equ (1)
4x-8(-2.8571)=12
4x=12-22.857=10.8571
x=
x=2.7142
Answer:
216 in 2
Step-by-step explanation:
Answer:
13/1*7/4
Step-by-step explanation:
The way you get this is by using the Keep, Change, Flip Method. 13 as a fraction would be 13/1, and this is the keep phase. The change phase is where you change division to multiplication. The flip phase is when we flip the numerator and denominator. Remember, this only works when dividing fractions.
Hey there! :D
Pay attention to the given angles.
We know that a circle is equal to 360 degrees.
We know two angles, and the other 2 are the same measure.
170+44= 214
Subtract that from 360, since that is what the circle equals.
360-214= 146
Divide that by two, since there are 2 equal angles left.
146/2= 73
<DOB= 73 degrees.
You were correct, so good work!
I hope this helps!

I’m pretty sure it’s 1640 or A.
