Think the answer is actually 0
Answer: the 5 in the parentheses on the second line should be negative. Also, where did the 23 go?? That's a mistake too.
Step-by-step explanation: 3 - 8 = -5 so
23(2 - 4) + 5(3 - 8)
23(-2) + 5(-5)
(-46) + (-25)
-71
(at least, I think so unless there was a mistake in the equation)
Answer:
A
Step-by-step explanation:
Step-by-step explanation:
Lets assume that x=0
Therefore- 2×0-y= -3
0 - y =-3
Therefore y = -3
Then lets take now the before equation
2x - 3= -3
2x = -3+3
2x=0
x=0÷2
∴ x= 0
Answer is- 0,-3
Answer:
120 degrees
Step-by-step explanation:
First, you need to find the measurement of the angle that is supplementary to D.
To do that you do 180-130=50, we know this is true because the two angles make a straight line.
Then you can find angle 2 because we have two of the angles in the triangle. All triangles have measurements of 180, we can use this information by doing
180-(50+70)=60, so angle 2 equals 60, then to find angle 1 you do
180-60=120, because they make a straight line.
angle 1=120
