Question

Mount McKinley is Alaska is 5910 feet higher

than Mount Rainier in Washington. Together,
their heights total 34,730 feet. How high is each
mountain?

Answer 1

20,320 feet

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 2

Mount McKinley = 34,730

Mount Rainier = 28,820

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
