Mrs. Lee has three children whose names are Larry, Curley, and Moe. Their mean age is 11. Their median age is 10. Moe is 15 years old. What is the age of the youngest child?

Solution :

1) age of the oldest teacher=54 years

age of the youngest teacher=23 years

2)Range=54-23=31 years

3)mean=sum of ages/number of people

mean=32+41+28+54+35+26+23+33+38+4010

mean=350/10=35 years.

umm 10?

Step-by-step explanation:

10 is the shortest of all 3 numbers you've just said...

you cant answer this dummy

step-by-step explanation:

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.
