Answer:
1. 2x can be seen as +2x therefore when you put it as +2x-5x the answer will be - 3x
2. +3a+2a also equals +5a
3. - 5 is left alone and there is no other similar expression
Put them together the answer becomes
-3x+5a-5
It doesn't have to be the same order of format but the numbers must be as such

Answer: 9/100
Step-by-step explanation:
Probability of people own a cat:
P(cat)=30/100=0.3
Probability of people own a bird:
P(bird)=3/100=0.03
Probability of both own a cat and a bird
P(cat and bird)=(30/100) × (3/100)
=90/1000=9/100=9%
Place a point on positive 3 and go up one and over one then do the opposite so down one over one, since the sign does not have an or equal to symbol, it will be a dotted/dashed line. shade the part that is greater than positive three. to find out if your answer makes sense, place a dot anywhere on the graph to see if it goes with your answer.
