The left side−8 is less than the right side48
,which means that the given statement is always true.
True
Equation 1 + equation 2
3x-8y +(-3x+10y) = 9+(-15)
2y= -6
then y=-3
from equation 1
3x-8y=9
3x-8(-3)=9
3x+24=9
3x=9-24=-15
then x=-5
Answer:
D 133 degrees
Step-by-step explanation:
The measure of an angle external to a circle = the difference of the two arcs intercepted divided by 2
47 = [ (360 - x) - x ] / 2
94 = 360 - 2x
x = 133 degrees of the arc
In the form of algebra substitution is the method used in simultaneous equations.
E.g y=2x+5 and y=5x-1
Solve for x and y
Since we know two examples of what y is, we can substitute one y in replacement of the other to get.
2x+5=5x-1 then we solve for x to get:
x = 2 sub this back in to get y = 2(2) +5
y = 9
Hi there!
Unfortunately, the beautiful fraction you've given us is simplified enough, and it cannot go any lower than what it is. So basically, you're left with
