Yes, your answer are correct! There is a little work to be shown on number 1, but it isn't necessary.
Hope this helps! Brainliest it if it does!
42 because you have to multiply the reciprocal
Answer:
5x+3y+(-x)+6z
5x+(-x)+3y+6z
4x+3y+6z
The facts to apply is PEMDAS which is parenthesis,exponents, multiplication,division,addition and subtraction.
Then group like terms if there are any.
You finally get to a simplified answer if there are no like terms
Answer:
there has to be a graph or table right?
Step-by-step explanation:
So first, you have to remember the order of operations. That means that whatever is in the parentheses is what has to be done first
However, because one of the numbers in the parentheses is a variable and the other isn't, we can distribute instead
Therefore, 3(12+4x) distributes by multiplying the 3 into both numbers in the parentheses. So we get 36+12x
Now the equation is 20=8+36+12x
Now, bring all numbers without variables on the left side
20-8-36=8-8+36-36+12x
20-8-36=12x
Now simplify
20-8-36=12x
12-36=12x
-24=12x
Divide both sides by 12, and you get x=-2
Hope this helped!!! :D
