If me.Arenth wants to put new carpeting in the room shown, how many square feet should he order

Mathematics

Liula [17]3 years ago

By definition, the area is given by:


A = w * l  


Where,


w: width


l: length


We have two expressions for the length:


L = 14\\L = 5 + 3c


Since the length is the same, we equate both expressions:


5 + 3c = 14  


From here, we clear the value of c:


3c = 14 - 5\\3c = 9  


c = \frac{9}{3}\\c = 3  


Then, we have that the width is given by:


W = 6c-8  


Substituting the value of c we have:


W = 6 (3) -8\\W = 18-8\\W = 10  


Finally, the area is given by:


A = w * l\\A = 10 * 14\\A = 140 ft ^ 2  


Answer:


he should order 140 square feet

Brianna has 4 pink bracelets. One third of all her bracelets are pink. How many bracelets does brianna have?
aivan3 [116]
Hey there!

Let's first evaluate this problem, and the keyword we need to use. The problem says that out of the total number of bracelets Brianna has, x, 1/3 of them are pink. The reason the word of is so important throughout math is that it signifies multiplication. For example, 1/2 of 10 is 5 because 1/2 times 10 is 5.

Now, to apply that to this situation, we need to create an equation, a mathematical statement that indicated the equilibrium or equality of two values. Since we have 1/3 of all her bracelets, x is four, we can set up our equation. Here's another good keyword- is. Is signifies an equation, because it means "equal to" mathematically. For example, 5 is equal to 20/4.

We have:

1/3(x) = 4 

(One-third of x, the total amount of bracelets, is four.)

We don't want that fraction there. In order to get rid of it and keep the expression equal, we multiply both sides by 3. We have,

x = 12

Hope this helps!
