Answer:
-6x + 22
Step-by-step explanation:
Note: This problem doesn't have a sign between 2 and 16, we would have to assume it is addition since 16 is 16 positive.
First we have to do distributive property,
-4 x 3x = -12x and -4 x -1 = 4
The equation should look like this:
-12x+4 + 6x + 2 + 16
Then combine like terms meaning do -12x + 6x
The answer should be -6x
The equation: -6x + 4 + 2 + 16
Then solve 4+2+16 which should equal 22
The answer: -6x + 22

C ( To make things simple, let's turn 80% into a fraction, 8/10. To get a common denominator let's turn 8/10 into 4/5. Since they are both of equal size, the first group would have 2/5 left-handed people and the second 1/5 left-handed people. Let's imagine that each group has 5 people in it. There would be 10 people in total. There is 1 person for each fifth so we can add now. 4 + 3 = 7 right handed people. To check, 2 + 1 = 3 and 3 + 7 = 10. so 7/10 of the class is right-handed. )
