Answer:
A. and C.
if you simplify the expressions, you will see which ones are equal to the expression given
part A is just simple multiplication
since there are 2 6 sided number cubes there are 36 possible outcomes(6 sides *6 sides)
Part B is a little trickier. First off, you must find how to get seven.
1. 1+6 and 6+1
2. 2+5 and 5+2
3.3+4 and 4+3
therefore there are six combinations
you put that number over the total combos and get 6/36 or 1/6.
Hope this helps!
The answer is 45 because if you divide 84 and 2 you get 42 and then add 3
The slope of a line and the perpendiular line that intercept will always have a product of -1
If the slope k=-1/6, the perperndicular line can be found by finding the product of the slope and -1
-1= (slope)(perpendicular line slope)
perpendicular line slope= slope(-1)
= -1/6(-1)
= 6
Average of 10 people = 65
65 × 10 = 650
average of 5 people = 35
35 × 5 = 175
650 + 175 = 825
825 ÷ 15 = 55
