Assuming these are two six-sided dice, you'll have 36 total combinations to test out. To get the 36, I just multiplied the 6 sides on both dice (6x6=36). First you have to test out all the possible combinations. Making it easier for you, I'll just list the ones that work. The combinations that work are 3+6, 4+5, 5+4, and 6+3. This means there are 4 combinations that work out of 36. This gives us the fraction 4/36. Now, this needs to be simplified. Both numbers are divisible by four, so we'll divide by four. The new fraction is 1/9, which is your answer. This means that, statistically speaking, if you rolled those two dice nine times, the sum of the numbers would be 9 only once. You have an 11% chance of having two numbers on the dice that have a sum of 9.
The answer is D because if you continue the pattern the bottom number would have to be 8 and the top would have to be 7!!
Answer:
A. 1 inch = 6 miles
Step-by-step explanation: We need to divide 30 by 5 to see how much 1 inch equals. 30÷5=6. We now known 1 inch = 6 miles.

Answer: the number of minutes of local calls that you made is 644
the number of minutes of international calls that you made is 208
Step-by-step explanation:
Let x represent the number of minutes of local calls that you made.
Let y represent the number of minutes of international calls that you made.
It cost $.06 per local call and $0.15 per international call you are charged $69.84. This means that
0.06x + 0.15y = 69.84 - - - - - - - - 1
The total number of calls add up to 852 minutes. This means that
x + y = 852
Substituting x = 852 - y into equation 1, it becomes
0.06(852 - y) + 0.15y = 69.84
51.12 - 0.06y + 0.15y = 69.84
- 0.06y + 0.15y = 69.84 - 51.12
0.09y = 18.72
y = 18.72/0.09 = 208
x = 852 - y = 852 - 208
x = 644
