Answer:

20,320 feet

Step-by-step explanation:

Let Mt Rainer be X.

Let Mt KcKinley be X+5,910.

So, X + (X + 5,910) = 34,730

Combine the variables and, 2X + 5,910 = 34,730

Subtract 5,910 from both sides and, 2X = 28,820

Divide both sides by 2 and, X = 14,410

So, Mt Rainer is 14,410 and Mt McKinley is (14,410 + 5,910) = 20,320

Answer:

Mount McKinley = 34,730

Mount Rainier = 28,820

Step-by-step explanation:

Step 1:

x + 5,910 = 34,730 Equation

Step 2:

x = 34,730 - 5,910 Subtract 5,910 on both sides

Step 3:

x = 28,820

Step 4:

28,820 + 5,910

Answer:

Mount McKinley = 34,730

Mount Rainier = 28,820

NO LINKS PLEASE JUST THE ANSWER TEHEHHE THANKSSSS :))))

goblinko [34]

Answer:

Since this is a multi-part question, just look at the bolded parts under each letter. I hope this helps a bit ;)

Step-by-step explanation:

All sides of a square are congruent. "s" represents the square's perimeter:

s=4x.

"r" is the rectangle's perimeter:

r= 4x+26

since the perimeter = 2W + 2L:

2W + 2L= 4x+ 26

and W=x, so:

2x + 2L= 4x + 26

Subtract from both sides:

2L= 2x +26

Divide both sides:

the length of the rectangle "L"= x +13.

B) Plug 5 into the equations:

L= 5+ 13 or 18.

2(18) + 2(5)= r

36+ 10 = r or 46

s= s+ 26

s= 46-26 or 20.

20/4= 5...

It seems (at least to me, feel free to give constructive criticism) that the only logical conclusion is that 5 could be the value of x.

C) You would likely need to use substitution to solve, but unless I am much mistaken, this looks like an infinite-solutions equation.

L=w+13
