Answer:
12n -5 ≤ 55
Step-by-step explanation:
12 times a number (represented by n) is 12n.
"Decreased by 5" means 5 is subtracted from the product, giving 12n-5.
"Is no more than 55" means "is less than or equal to 55".
Then the expression written using math symbols is ...
12n -5 ≤ 55
Answer:
Step-by-step explanation:
Add 9 to both sides:
Subtract 6a from both sides:
Divide both sides by -8:
Answer:
C.) P(5, H) = 1/12
Step-by-step explanation:
Answer:
Step-by-step explanation:
Since 
have the same denominators, we add them first. We then add 
to the result.
(12 x 9) + (12 x 6/2). The answer would be 144 but rounded it would be 100
