Answer: =4.4n-13
Step-by-step explanation:
Let's simplify step-by-step.
2n−9−(−2.4n+4)
Distribute the Negative Sign:
=2n−9+−1(−2.4n+4)
=2n+−9+−1(−2.4n)+(−1)(4)
=2n+−9+2.4n+−4
Combine Like Terms:
=2n+−9+2.4n+−4
=(2n+2.4n)+(−9+−4)
=4.4n+−13
When exponents are separated by a parenthesis it means you need to add them. Because the parenthesis is around the entire number then you raise everything inside the parenthesis to the outside exponent. Then anything raised by 0 as an exponent is automatically 1.
You think of this visually as 3a*3a*3a= 27a^9 is your answer
There are six sides on a dice.
If it is going to roll greater than 2, then it will be either a 3, 4, 5, or 6.
This is four out of the six sides.
Therefore the fraction is 4/6.
It can be reduced to 2/3.
