To simplify 2x+3-x+5, we can first group x together,then calculate:

Therefore the answer is x-2.
Hope it helps!
Answer:
n=10
p=0.5
k=5
Step-by-step explanation:
n represents = number of trials
p represents = probability of success
k represents = number of successes
97, 19+(11+37)=19+(48)=67 and then add 30 because of 19 and 11 and you get 97
There are 9 diagonals.
Please see the attached picture for all the vertices that are drawn. When you start drawing the diagonals, be cautious of the ones that you have already drawn.
remove parenthesis : 2/3 - 5/6 + 9/4 - 3/5
add fractions based on lcm : 40/60 - 50/60 + 135/60 - 36/60
equal denominator so combine fractions : 40 - 50 + 135 - 36 / 60
add/subtract : 40 - 50 + 135 - 36 = 89
answer ; 89/60
