Add up equation 1 and 2 to eliminate b
(a+b)+(-b+c)=3+3 => a+c=6
subtract this new equation from the third equation:
(a+2c)-(a+c)=10-3 =>c=4
plug in c=4 in a+c=6 =>a=2
a+b=3, a=2 =>b=1
N is the variable, you solve by subtracting 6 from 20, getting n = 14.
Step-by-step explanation:
3 units up: y = |x|+3
7 units right: y = |x—7|
3 units up & 7 units right: y = |x—7| + 3
Answer:
120
Step-by-step explanation:
The sum of the angles in a quadrilateral is 360 degrees
2t+t+2t+t = 360
6t = 360
Divide by 6
6t/6 = 360/6
t = 60
Angle Z = 2t
Angle Z = 2*60 = 120
