Answer:
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
y+2=y+2
Step 2: Subtract y from both sides.
y+2−y=y+2−y
2=2
Step 3: Subtract 2 from both sides.
2−2=2−2
0=0

All real numbers are solutions.
Answer:
11340
Step-by-step explanation:
We have 10 cheerleaders of ten different heights. There are two rows each having 5 positions so that five cheerleaders occupy the first row that have height less than the five cheerleaders who occupied the second row.
Therefore, Out of ten cheerleaders, two cheerleaders will be selected out of which the tallest one will occupy the position in the upper row and the second one will occupy in the lower row, therefore these two positions will be occupied in 
ways. Now, we are left with 8 cheerleaders and following the same path, the next two positions will also be occupied in 
ways, similarly, following the same path, the number of ways the cheerleaders will occupy the position will be: ××

Answer:
Step-by-step explanation:
A bag contains 8 red marbles, 3 blue marbles and 7 green marbles.
Total = 18 marbles.
Probability of drawing three red marbles = probability of drawing one red without replacement + probab of drawing another without reeplacement + probab of drawing a third without replacement.
Probability of drawing three red marbles = 8/18 + 7/17 + 6/16 = 0.4444 + 0.4118 + 0.3750 = 1.2312.
