Subtract 6 from both sides
49>-7x
Divide by -7 (Remember to flip the inequality sign when dividing by negatives)
-7

Answer:
a. 0.6
b. 0.5
Step-by-step explanation:
Let A be the event that student takes algebra and C be the event that student takes Calculus 3.
P(A)=0.60
P(C)=0.5
P(A and C)=0.30
a.
We have to find P(A/C).
P(A/C)=P(A and C)/P(C)=0.3/0.5=0.6
Thus, if someone took Calculus 3, the probability that he/she took Linear Algebra too is 0.6 or 60%
b.
We have to find P(C/A)
P(C/A)=P(A and C)/P(A)=0.3/0.6=0.5
Thus, if someone took Linear Algebra, the probability that he/she took Calculus 3 too is 0.5 or 50%
