I need to know how many miles the race is
Answer: There are 2346953264 ways to do so.
Step-by-step explanation:
Since we have given that
Total number of selected countries = 12
Number of selected countries from a block of 45 = 3
Number of selected countries from a block of 57 = 4
So, remaining number of selected countries from a block of 69.
So, 12-(3+4)=12-7=5
Now, we need to find the number of ways, so we will use "Combination" to select that number of countries.
So, it becomes.

Hence, there are 2346953264 ways to do so.
Put the equation in Photo math
Answer:
-8
Step-by-step explanation:
well since the equation has the <em>same base</em> of 11, you can just solve for x as you normally would. so the question becomes:
4x+1 = 3x -7
<em>subtract one from both sides</em>
4x = 3x - 8
<em>subtract 3x from both sides</em>
x = - 8
