Answer:
x = 12
Step-by-step explanation:
sqrt(x+4) - 3 = 1
First get the sqrt all by itself on one side of the equation. Add 3 to both sides of the equation.
sqrt(x+4) = 1 + 3
sqrt(x+4) = 4
To "fix" the sqrt, that is, "undo it" and get rid of it, you have to SQUARE both sides of the equation.
(sqrt(x+4))^2 = 4^2
x + 4 = 16
subtract 4 to finish up.
x = 12
Check:
sqrt(12 + 4) - 3 = 1
sqrt16 - 3 = 1
4 - 3 = 1
1 = 1 Check!

Let the number of coats Michael has = x
As given, Minnie gathers 3 times as many coats as Michael
So, Minnie has = 3x
Total number of coats = 52
Equation becomes,
Hence, Michael contributed 13 coats.

Answer:
4 girls have short red hair
Step-by-step explanation:
Total number of guests at the party is 32
1/2 of the guests are boys
The number of girls with long hair is
= 32×1/4
= 8 girls.
The number of girls with short blonde hair is:
= 16×1/4
= 4 girls
Therefore, we apply the formular below to calculate the maximum number of girls with short red hair.
Total number of girls- ( girls with long hair+ girls with short blonde hair)
= 16-(8+4)
=16-12
= 4
Thus, 4 girls have short red hair
