Based on the shipping rate and the price of the t-shirts, it can be concluded Sam ordered a total of 6 t-shirts.
<h3>What equation represents Sam's situation?</h3>
5.99 + x12.50 = 80.99
x represents the number of t-shirts she bough, which is the focus of the equation.
Let's solve it:
- 5.99 + x12.50 = 80.99
- x12.50 = 80.99 - 5.99
- x12.50 = 75
- x = 75 / 12.50
- x = 6
<h3>How many t-shirts did Sam order?</h3>
Sam ordered 6 t-shirts.

If width is w the length can be represented as 5/2+2w.
Formula for perimeter is 2l + 2w
So it would be 2w + 2(5/2 + 2w)
OR 2w + 5 + 4w
OR 6w + 5

Answer:
26 mph
Step-by-step explanation:
First find the time Adrian takes to get to school
I found it easiesT to use the method of ratio and proportion
40:60
16:x
x= 16 x 60 / 40 = 24 minutes
So, he has 60-24 minutes to return home, that is 36
What is his speed if his time is 36 minutes= 0.6 hours
Speed = Distance divided by time = 16/0.6 = 26.6 miles per hour.
Hope this helps
Good Luck
Answer: The perimeter is going to increase 25% from the square to the pentagon.
Step-by-step explanation:
- A square is a quadrilateral having its all sides equal.
- A equilateral triangle is a triangle that has equal sides.
Let the side of the given square be x.
Perimeter of square =4x
If a square is changed into a pentagon by building an equilateral triangle on top of it , Then the base of equilateral triangle will occupy the same side-length as that of square.
Thus , the pentagon will become a regular pentagon having all its sides equal.
Perimeter of pentagon = 5(side)= 5x
Increase in perimeter = Perimeter of pentagon- Perimeter of square
= 5x-4x= x
Now , the percent increase in perimeter = ![\dfrac{\text{Increase in perimeter}}{\text{Perimeter of square}}\times100](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Ctext%7BIncrease%20in%20perimeter%7D%7D%7B%5Ctext%7BPerimeter%20of%20square%7D%7D%5Ctimes100)
![=\dfrac{x}{4x}\times100\\\\ =\dfrac{100}{4}=25\%](https://tex.z-dn.net/?f=%3D%5Cdfrac%7Bx%7D%7B4x%7D%5Ctimes100%5C%5C%5C%5C%20%3D%5Cdfrac%7B100%7D%7B4%7D%3D25%5C%25)
Hence, the perimeter is going to increase 25% from the square to the pentagon.
