Answer:
median: 10 <h <13
mean: 12.12
Step-by-step explanation:
Answer:
x + x+12 + 3(x+12) = 123
x = 15
Step-by-step explanation:
Jamil : x
Kiera : x+12
Luther : 3 ( x+12)
x + x+12 + 3(x+12) = 123
Distribute
x + x+12 + 3x+36 = 123
Combine like terms
5x+ 48 = 123
Subtract 48 from each side
5x+48-48 = 123-48
5x =75
Divide by 5
5x/5 = 75/5
x = 15
Answer:
12/5 is 2.4 so

Answer:
x = 88
Step-by-step explanation:

x + 92 =180
Subtract 92 from each side
x+92-92=180-92
x =88
