B.
if you plug in the points you get for the first one
3(3) - (4/(-8)) = 9+2 = 11
and the second
3(4) - (4/4) = 12-1 = 11
The answer would be 1/3. You should add up the flags, and then divide the number of desired outcomes (5) by the total number of outcomes (15). Reduce it to simpler terms when finished.
Hope that helps :)
2) 5 plus 2c is equal to 15
Answer:
quadratic
Step-by-step explanation:
Answer:5 and 3
So we let the number take the letter b, anc the expression of the question is:
b^2+15=8×b.....so
b^2+15=8b
Then we take the 8b to the other side of the equal sign so that it becomes...
b^2+15-8b=0
Hence it becomes a quadatic equation following the principle ax^2+bx+c where x is the unknown...
From there we work out to get two different numbers...either b-5=0
b=5
Or b-3=0
b=3
So the two numbers are 5 and 3
