Answer:

x = 15

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

∠ KLM is an external angle of the triangle, thus

∠ KLM = ∠ JKL + ∠ KJL , substitute values

5x - 7 = x + 20 + 2x + 3

5x - 7 = 3x + 23 ( subtract 3x from both sides )

2x - 7 = 23 ( add 7 to both sides )

2x = 30 ( divide both sides by 2 )

x = 15

What is 3x3-45 divided by (4+1)
Lorico [155]

Answer:

3x3-45÷(4+1) is 0.

Step-by-step explanation:

We have to do order of operations so we follow PEMDAS:

P is for Parentheses so we do what's in parentheses first:

(4+1)=5

E is for Exponents but we don't have exponents.

Next is M and D for Multiplication and Division. We have division before multiplication so we should do division first:

45÷5=9

We now have multiplication:

3x3=9

Now we have A and S for addition and subtraction

We don't have addition so we'll do subtraction:

9-9=0

The final answer is 0.

Hope this helps! :)
