Answer:
70 degrees
Step-by-step explanation:
Supplementary means the angles add up to 180 degrees. We can set up an equation using this:
9x+20+6x+10=180
Combine like terms.
15x+30=180
Isolate variable.
15x=150
x=10
Substitute in the variable for the expression of angle B
6(10)+10=70
Hope this helps!

Step-by-step explanation:
The ratio of adult to children is determined by number of adult / number of children.
We want to determine the three ratios that are equivalent to 2 adults 5 children. So we will divide each of the given number of adults and children.
1) 8 adults 20 children = 8/20 = 2/5
2) 5 adults 8 children = 5/8
3) 20 adults 50 children = 20/50 = 2/5
4) 4 adults 10 children = 4/10 = 2/5
So the three ratios that are equivalent to 2 adults 5 children are
8 adults 20 children,
20 adults 50 children and
4 adults 10 children
Answer:
