Answer:
Yes
Step-by-step explanation:
-2x = -1
x = 1/2
Any equation that returns x=1/2 is a solution to this problem. For example, x= (3•4)/6 can be simplified so that x=1/2
Y=42 Y=?
X=6 X=3
cross multiply
so 42times3=6timesY
126=6Y
Y=126 divided by 6
=21
Answer:
20
Step-by-step explanation:
When looking for the perimeter just add all the numbers together.
Answer:
x = 13.5°
Step-by-step explanation:
Angles 2 + 3 = a straight line, so 180°
180 - 66 = 114 = angle 2
114 = 10x - 21
114 + 21 = 10x
135 = 10x
135 / 10 = x
13.5 = x
