Answer:
x/3 -3= 18 (add three to both sides)
x/3= 21
x/3(*3) =21(*3) (multiply by 3 on each side to cancel out the division)
x= 63
63/3-3=18
21-3=18
18= 18 (checking answers)
Step-by-step explanation:
12, Find the prime factorization of 60
60 = 2 × 2 × 3 × 5
Find the prime factorization of 144
144 = 2 × 2 × 2 × 2 × 3 × 3
To find the gcf, multiply all the prime factors common to both numbers:
Therefore, GCF = 2 × 2 × 3
<h3>
Answer: K ' is at (1, 4)</h3>
Explanation:
Point K is located at (1, -4)
We use the rule that 
when reflecting over the x axis.
The x coordinate stays the same, but the y coordinate flips from positive to negative or vice versa.
Therefore, K(1,-4) will move to K ' (1, 4)
Probability of passing history course = 0.59
Probability of passing math course = 0.60
Probability of passing both courses = 0.49
Probability of passing at least one = 0.59 + 0.60 - 0.49 = 0.7 ##
