Answer:
x = 18
Step-by-step explanation:
Add the opposite of the constant (-5), and multiply by the inverse of the coefficient of x (2/3).
Let us say that:
x = age of brad
x + 2 = age of Alexandra
(x + 2) – 3 = age of Cecilia = x – 1
We are also given that:
x + x + 2 + x – 1 = 37
<span>
solving for x:</span>
3x + 1 = 37
3x = 36
x = 12 = age of brad
x + 2 = 14 = age of Alexandra
<span>x – 1 = 11 = age of cecilia</span>
Answer:
4/14 or 29%
Step-by-step explanation:
So p(B|A) basically means that we are finding the probability of b now that a has already happened.
In this scenario once a has happened, there are 3 blue balls, 7 yellow, and 4 white so the probability is 4/14 which is approximately 29%
Sid wrapped 8 gifts.
Look at the equation Sid wrote to caclulate the cost to wrap each gift. (6.80 + 7.35) / 8. 6.80 represents the total paid for wrapping paper. 7.35 represents the total amount paid for ribbon. Knowing that information, using the equation, and knowing who Sid wrapped gifts for, we can infer Sid wrapped gifts for 8 cousins.
