2 gallons divided between 9 people would equal 0.222222222 gallons per person
$3150 because 9% of $25000 is $2250 and 15% of $6000 is 900 and 2250+ 900 is 3150
Answer:
12.5
Step-by-step explanation:
5/2*5=12.5
Commutative property of multiplication is shown above. This is because no matter how you put them, the answer will still be 140.
You need this key result: in any polygon, the sum of the interior angles is

where
is the number of sides of the polygon.
Your polygon has seven sides, and the measures of all angles are given. So, we can write

Again, we've simply written that the sum of all interior angles is the number of sides, minus two, times 180.
We can simplify both sides: we sum like terms on the left hand side, and we easily compute the right hand side:

and we can solve this equation for
by dividing both sides by 30:

Finally, the required angles is
