The answer is 1/4.
(n+9)/4(n+9)=1/4
The Probability is 2/6 and 3/6. 2/6= 1/3 and 3/6=1/2 The ratio is 1/6
Answer:
4 - x
Step-by-step explanation:
product means multiply
the product of 1 and x = 1 × x = x
This is then subtracted ( minus ) from 4 giving
4 - x ← expression representing the situation
3x = B
(x + 80 = 1/2B) * -3
-3x-240 = -3/2B
-240 = -1/2B
B=480 pennies
