Answer:
Well, it's the perimeter, so...40.
You just calculate the perimeter of a rectangle with the lenght of 12 and width of 8, by the formula
![P = 2L+2W](https://tex.z-dn.net/?f=P%20%3D%202L%2B2W)
or you can factor it out.
Answer:
30x - 18y + 24
Step-by-step explanation:
When the distributive property is in play, you multiply all the numbers in the parenthesis by the number that's right next to it. In this case, you're multiplying 6 to all of the numbers in the paranthesis (5x - 3y +4).
Answer: B. x = 2/4
Reason:
The thing they need to share are the sandwiches (y), where x is the amount of sandwich per person, so that goes in the equation first.
4/2 is 2 so that doesn’t make sense.
C isn’t an option because there are 4 people in this word problem. Don and his 3 friends = 4.
D isn’t right because there’re 2 sandwiches, not 1.
Answer:
0.619 = 61.9% probability of choosing a professor or an instructor.
Step-by-step explanation:
A probability is given by the number of desired outcomes divided by the number of total outcomes.
In this question, we have that:
7 + 4 + 4 + 6 = 21 members
7 + 6 = 13 professors or instructors.
Find the probability of choosing a professor or an instructor.
p = 13/21 = 0.619
0.619 = 61.9% probability of choosing a professor or an instructor.
