<h3>Answer: 10</h3>
============================================
Work Shown:
First add up all the ages
9+13+9+10+10+9+10+10+11+9 = 100
Then divide that sum by 10, since there are 10 values we added up
100/10 = 10
The average age is 10 years old.
Fraction does not make sense this question
Answer:
the answer would be 16 then you square it and it 256
x+3(x-5)=9 Substitute y=x-5 into every y into the first equation and solve for x
x+3x-15=9
4x=24
x=6
Substitute x into any equation and then solve for y.
y=(6)-5=1
x=6, y=1
Hope that helps!
Answer:
h = f/7g
Step-by-step explanation:
You have to rearrange the equation so that h is alone on one side.
f = 7gh
f/7g = (7gh)/(7g)
f/7g = h
h = f/7g
