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.

1) Construct equations

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

2) Solve for one of the integer

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.

3) Solve for the other integer

$x+y=33$

Plug in y (9)

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

Therefore, the larger integer is 24.

I hope this helps!

vladimir2022 [97]

Answer:

Step-by-step explanation:

let he works at first store x hours and at car wash y hours. Then

x+y=25

multiply by 4

4x+4y=100 ...(1)

12x+15y=333

divide by 3

4x+5y=111 ... (2)

(2)-(1) gives

y=111-100=11

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.
