Answer #1:
11/18
Why?
Since you’re adding fractions, you need to find the lowest common denominator.
The LCD of 2 and 9 is 18. Multiply the numerator and denominator of 1/2 by 9 and for 1/9, multiply both by 2.
Now you have 9/18 + 2/18. In addition, you don’t touch the denominators when they’re the same, and just carry them over. You only add the numerators. So, 9/18 + 2/18 = 11/18.

Answer #2:
15/16
Why?
Since you’re adding fractions again, you need to find the lowest common denominator.
The LCD of 4 and 16 is 16. This means you only have to change the first fraction and not the second one. Multiply the numerator and denominator of 3/4 by 4, giving you 12/16.
Now you have 12/16 + 3/16. You don’t touch the denominators when they’re the same, and just carry them over. You only add the numerators. So, 12/16 + 3/16 = 15/16.

-1/3(n+15)=-2. what is n? please show work on paper and send it to me asap.​
Anton [14]

Step-by-step explanation:

Use the distributive formula to solve for n:

-a(b + c) = -ab - ac

So, to solve this you would have to use the distributive property:

-1/3n - 5 = -2

Add 5 to both sides

-1/3n - 5 + 5 = -2 + 5

-1/3n = 3

Now, multiply -3 from both sides

-1/3 * -3 n = 3 * -3

Simplify

n = -9

Hope that helped!!

(No links please) There were 2 red marbles, 3 blue marbles and 5 gold marbles in a bag.
Rashid [163]

Answer:

5/9

Step-by-step explanation:

You started with 10 marbles total. You removed one marble and did not replace it, so you now have 9 marbles. The marble that you removed was NOT a gold marble, so you still have 5 gold marbles.

This means that out of the 9 marbles that you have left, 5 of them are gold.

This means you have a 5/9 chance of drawing a gold marble next.

Identify the action-reaction pair when a softball player hits a home run
Mariulka [41]

Answer:

Newton's third law of motion states that every action has an equal and opposite reaction. In softball when the catcher catches the ball the two forces present are the mitt on the ball and the ball on the mitt. The two are equal and in opposite directions.
