Which expression simplifies to 41? choose all that apply!
10+ 2.4 - 1
10 + 2 . (4 - 1)
(10 + 23). 4 - 1
| 10 + (2². 4) - 1

None of the expressions is simplified to 41.

Step-by-step explanation:

You have to follow the P.E.M.D.A.S., this is:

P:Parentheses first.

E:Exponent next.

M:Multiplication.

D:Division.

(Multiplication and Division is whichever come first, from left to right)

A: Addition.

S: Subtraction.

(Addition and Subtraction is whichever come first, from left to right).

We are going to analyze every option:

1. 10+ 2.4 - 1

First we have to solve the multiplication:

Now we have to solve the addition and subtraction from left to right:

This is not a correct answer.

2. 10+2.(4-1)

We have to solve the parentheses first:

Now the multiplication and then the addition.

This is not a correct answer.

3. (10+23).4-1

We have to solve the parentheses first:

Now the multiplication and then the subtraction:

This is not a correct option.

4.

We have to solve the parentheses first, in the parenthesis first we have to solve: and then do the multiplication.

Now we have to solve the addition and subtraction from left to right:

This expression is not a correct option.

Then none of the expressions is simplified to 41.

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180
