Answer:
15x - 40 = 8
Step-by-step explanation:
3/4x-2=2/5
Multiply each side by 4*5 or 20
20 (3/4x-2=2/5)
15x - 40 = 8
The four outcomes are:
HH
HT
TH
TT
There are 4 outcomes that are possible. I've never seen anyone flip and edge, so that does not count.
Answer:
This system has no points of intersection.
Step-by-step explanation:
The lines are parallel, so they don't intersect.
I graphed the equations below to show you how they are parallel.
Answer:
Step-by-step explanation:
Y=-2x+2.....(1)
Y=-2x-2.....(2)
Subtracting (1) from (2)
Y - Y = -2x - (-2x) -2 - 2
O = -2x + 2x - 4
O = 0 - 4
Hence it as no solution the the two variables tend to zero
Any quadrilateral has sum of all angles equal 360⁰.
So,
m∠D+78+91+90=360
m∠D=360-(78+91+90)=101⁰
Answer is A.
