question 2(multiple choice worth 4 points) (07.03) bobbi, kate, and rebecca earned a combined 12 points during their team's game. bobbi earned 6 points and kate earned 3 points. which of the following equations can be used to determine how many points rebecca earned? 6 + 3 + n = 12
3x + 6 = 12
6 + 3 = 12 + n
6x + 3 = 12

fraction 3 over 8
fraction 5 over 12
fraction 11 over 12

Hey!

Hope this helps

For Question 2: 6+3+n=12

This is because we know that there is a combined total of 12, so it has to equal 12 (which cancels out C), we also know that the question is not saying anything that implys that we are multiply anything thing (which cancels out B, and D), so we are only left with A.) 6+3+n=12

For Question 4: 2 (Fraction 2 over 3)

This is because when we substitute all those choices in for y, we get...

2/(3*(3/8)) ~ 1.77778

2/(3*(5/12)) = 1.6

2/(3*(11/12)) ~ 0.727273

2/(3*(8/3)) = 0.25

I got 8/3 from A (b/c) > ((A*c)+b)/c

(And we know 1/4 = 0.25)

use substitution to solve each system of equations. y = x + 5 3x + y = 25 62/87,21 y = x + 5 3x + y = 25 substitute x + 5 for y in the second equation. substitute the solution for x into either equation to find y. the solution is (5, 10)
