Answer:
27
Step-by-step explanation:
First solve 3a - 9= 6
3a - 9 = 6 add 9
3a = 15 divide by 3
a = 5
Now that you know a is 5, put that in the other expression.
5a + 2
= 5(5) + 2
= 25 + 2
= 27
Answer:
Event 1: Rolling a number cube has 6 possible outcomes. Event 2: Flipping a coin has 2 possible outcomes. There are 12 possible outcomes.
First you multiply 6(x) then you multiple 6(8)
Your equation should now look like this: 6x-48=72
Subtract 48 from both sides
Your equation should now look like 6x=120
Divide by 6
Answer is 20
The measure of each interior angle would be (16-2)180=2520, but then you need to divide 2520 by 16, so the answer is 157.5 degrees. Each exterior angle would be 22.5, because you take 360 and divide it by 16.
