Answer:
x<5
Step-by-step explanation:
2x-3>7 you add three to both sides
2x>10 you then divide 2x by 2 and 10 by 2 which switches the symbol around
x<5 that's the answer
Answer:
k = 4
Step-by-step explanation:
Rearrange so that like terms are on either side of the equation
4k - 2k - 2k + 2k = 5 + 3
Simplify
2k = 8
Divide both sides by two to make k on its own
k = 4
You are correct, well done!
Answer:
Step-by-step explanation:
1) x+27=1
-27 -27
x = -26
2) x-2y=5 (solving for x)
+2y +2y
x = 5 + 2y
2) x-2y=5 (solving for y)
-x -x
2y = 5 -x
2y/2 5/2 -x/2
y = 5 - x
_____
2 (5-x over 2)
Answer:The probability of the complement of an event is one minus the probability of the event. Since the sum of probabilities of all possible events equals 1, the probability that event A will not occur is equal to 1 minus the probability that event A will occur.
Step-by-step explanation:Complement of an Event: All outcomes that are NOT the event. So the Complement of an event is all the other outcomes (not the ones we want). And together the Event and its Complement make all possible outcomes.
