10. The perimeter of the table shown is 16 feet. Write an equation in

Aliun [14]

Answer:

p = 2

q = 6

r = 16

x = 5 feet

Step-by-step explanation:

The perimeter of the rectangle is

$P=2(\text{Width}+\text{Length})$

In your case,

Width = 3 feet

Length = x feet

So, the perimeter is

$P=2(3+x)\\ \\P=6+2x$

Since the perimeter is 16 feet, we have

$2x+6=16$

Hence,

p = 2

q = 6

r = 16

Solve this equation for x:

$2x+6-6=16-6\\ \\2x=10\\ \\x=\dfrac{10}{2}=5\ feet$

The sum of three consecutive odd integers is 207. What are the integers?

nikdorinn [45]

Hey!

It says that it is the sum of 3 consecutive odd integers right?

So then we give these numbers some variables to work with like so...

x = 1st number
x + 2 = 2nd number
x + 4 = 3rd number

now set all of them equal to 207

x + x + 2 + x + 4 = 207
3x + 6 = 207
3x = 201
<u>x = 67</u><u /> <u>x + 2 = 69</u><u /> <u /><u /> <u>x + 4 = 71
</u><u>

Dale has a special deck of cards. Each card has a different rational number on it. The cards are 0.25,4/5,2/9,0.48, and 8/11. Ho

STALIN [3.7K]

<span>There are two cards which have a value greater than 1/2. In order to calculate this, you need to look at the numbers. 0.25 equals 1/4, which is not greater than a half. 2/9 would also not be greater than one half. 1/2 is .50, so .48 would also not be greater.</span>
