The sum of two integers is 33. The larger is 6 more than twice the smaller. Find the two
grandymaker [24]

Answer:

24 and 9

Step-by-step explanation:

Hi there!

Let x be equal to the larger integer.

Let y be equal to the smaller integer.

<u>1) Construct equations</u>

  1. x+y=33 (The sum of two integers is 33)
  2. x=6+2y (The larger is 6 more than twice the smaller)

<u>2) Solve for one of the integer</u>

Isolate x in the first equation

x+y=33\\x=33-y

Plug the first equation into the second

33-y=6+2y

Combine like terms

33-6=2y+y\\27=3y\\9=y

Therefore, the smaller integer is 9.

<u />

<u>3) Solve for the other integer</u>

x+y=33

Plug in y (9)

x+9=33\\x=33-9\\x=24

Therefore, the larger integer is 24.

I hope this helps!

Is the sum of two angles sometimes , always , or never an obtuse angle ?
k0ka [10]
An obtuse angle would be an angle more then 90 degrees.

So if you add two angles together, it could be less then 90 degrees, such as 30 + 50 = 80 degrees.

However, it can also be more then 90 degrees, or an obtuse angle, for example 60 + 50 = 110 degrees.

So it's sometimes.
