Sum of <span>Interior Angles with n = 6</span>
(n-2) × 180° = 4 x 180 = 720
A = 720 - (50+100-120-110 - 230)
A = 110
answer is A. 110
There are 4 eights in a deck of cards so it would be 4 out of 52 or 4/52 = 1 out of 13
Answer:
X = 3
Step-by-step explanation:
First count the amount of X's. There are 5 and it is plus two. Both sides should be equal in value so you have to set up your equation.
5x + 2 = 17
Then Solve For X
5x + 2 = 17
Subtract 2 from both sides
5x = 15
Divide by 5
X = 3
Check your answer
5(3) +2 = 17
15 + 2 = 17
17 = 17
It is correct!
If the ratio is 4:1 , pencils being the 4 and erasers being the 1, there are 4 pencils for every 1 eraser. Now, substitute the 4 pencils for 20 pencils. How do you get to 20 from 4? multiply by 5. You multiply the 4 pencils by 5 to get 20, and u multiply the 1 eraser by 5 to get 5, so there are 20 pencils: 5 erasers
