Answer: 
Step-by-step explanation:
Given the equation 
you need to solve for the variable "b".
You need to apply Distributive property on both sides of the equation:
Now you need to add 21 to both sides of the equation:
Subtract 
from both sides:
And finally, you can divide both sides of the equation by 18:
Answer:
31%
Step-by-step explanation:
To determine the probability of obtaining 3 or any number in a roll, we divide the number of outcomes with the sample space.
probability of 3 : n = 6/64 = 3/32 = 0.09375
probability of 4 : n = 14/64 = 7/32 = 0.21875
Since, we use the conjuction "or", we therefore add up these probabilities.
n = 5/16 or 0.3125

As I understand, in this exercise, we have the following numbers:
By using calculator, let's convert those numbers into decimal form:
So arranging from least to greatest we have:
Put another way:
Answer:
85
Step-by-step explanation:
x+2x+5=125
3x+5=125
3x=120
x=40 in the morning
85 in the afternoon
-2, -2, -2, +2
-2 + -2 + -2 + 2
-2 -2 -2 + 2
-6 + 2
-4
-4/ 4 = -1
His average is -1
