Answer:
2
Step-by-step explanation:
2-x=x -2
so making x the subject of formula
-x -x =-2-2
- 2x=-4
x= -4/-2
x=2
A+b=180° because they are a linear pair
(2x+10)+(3x+20)=180
5x+30=180
5x=150
x=30
a=c because they are vertical angles
2(30)+10= C
60+10=C
70=C
Answer:
60%
Step-by-step explanation:
12 kids played. 8 didn't play. That means there is a total of 20 students.
The fraction would be 12/20.
To make it into a percent, divide 100 by the denominator (20) and multiply it by the numerator (12)
100 divided by 20 is 5
12 x 5 = 60
