8/1 bec ause 40 divided by 5 = 8 and 5 divided by 5 = 1
Hey there! :)
2(3/5n + 3) - (2/3n - 1)
Simplify.
(2 * 3/5n) + (2 * 3) - (2/3n -1)
Simplify.
6/5n + 6 - 2/3n + 1
Add like terms.
(6/5n - 2/3n) + (6 + 1)
Make the fractions have the same denominator by multiplying fraction 1 (6/5n) by 3/3 and fraction 2 (-2/3n) by 5/5.
6/5n * 3/3 = 18/15n
-2/3n * 5/5 = -10/15n
So, our new equation looks like this : (18/15n - 10/15n) + (6 + 1)
Simplify.
8/15n + 6 —> final answer.
Hope this helped! :)
Answer:
πd=6786 miles
3.14×d=6786
d=6786/3.14
d=2161.146 miles approximately
Answer:
The correct answer is x = 12.
Step-by-step explanation:
To solve this problem, we must remember that an angle bisector divides the angle into two smaller, equal angles. This means that we can set the values for each of these smaller angles equal to one another, given that the angle is bisected. This is modeled below:
9x - 54 = 4x + 6
Now, we can solve this equation like any other. The first step is to subtract 4x from both sides.
9x - 4x - 54 = 4x - 4x + 6
5x - 54 = 6
Then, we should add 54 to both sides.
5x - 54 + 54 = 6 + 54
5x = 60
Finally, we can divide both sides by 5.
5x/5 = 60/5
x = 12
Therefore, the correct answer is x = 12.
Hope this helps!
