The perimeter of her bedroom is 36.67 ft.
Step-by-step explanation:
Julisa's bedroom is similar to her brother's bedroom.
If the width of her bedroom is w and the length is l and her brother's room has width W and length L, then
............. (1)
Now, the dimensions of her brother's bedroom are given by 12 ft long by 10 ft wide and her bedroom has length 10 ft.
Then, from equation (1) we get,

⇒ w = 8.33 ft.
Therefore, the perimeter of her bedroom is 2(8.33 + 10) = 36.67 ft. (Approximate) (Answer)
Answer:
Shirt: $45 , Tie: $12
Step-by-step explanation:
Let s be the price of the shirt
Let t be the price of the tie
Given the information from the question,
s + t = 57 - Equation 1
s - t = 33 - Equation 2
We will use substitution method to find the prices.
We will rearranging equation 1.
s = 57 - t
We will substitute s into equation 2.
57 - t - t = 33
57 - 2t = 33
-2t = 33 - 57
-2t = -24
t = -24 / -2
= 12
We now substitute t into Equation 1.
s + 12 = 57
s = 57 - 12
= 45
From here we know, the shirt costs $45 and the tie costs $12
