The Answer is A: 255.4 I took the test
Answer:
36
Step-by-step explanation:
39+1-24/6 =
we gotta follow pemdas so we divide 24 by 6 first
39+1-4=
then its just adding and subtracting so just go left to right
40-4=
36
Answer:
I solved it and attached it in the file!
When you have a negative exponent, you move the variable with the negative exponent to the other side of the fraction to make the exponent positive.
For example:
or 
(you don't move the "2" because "2" has an exponent of 1, only "y" has the negative exponent)

When you multiply a variable with an exponent by a variable with an exponent, you add the exponents together. (But you can only combine the exponents when the variables are the same)
(You can't combine them because they have different variables of x and y)


There's two ways you can do this. Either by first making all the exponents positive then do subtraction, or multiply them then make all the exponents positive. I'm doing the 2nd way.
You can combine the numbers 2 x 9 x 2 = 36
Now multiply the terms with the same variables
Now make all the exponents positive

If you were to do subtraction, here is what you need to know:
When you divide a variable with an exponent by a variable with an exponent, you subtract the exponents together. (Reminder: they have to be the same variable in order to combine the exponents)
For example:
or x

we are given
m∠BCD =67
and m∠BDC=60
we know that
m∠ABC is exterior angle
m∠BCD and m∠BDC are interior angles
exterior angle is sum of interior angles
so, we can write it as
m∠ABC=m∠BCD+m∠BDC
now, we can plug values
and we get
m∠ABC=60+67
m∠ABC=127
so, option-4.........Answer
