5 0

Answer:

You gave away 15 pieces of candy.

Step-by-step explanation:

Let x represent the number of pieces you give to friends.

Your equation:

30 - x

Your neighbor's equation:

45 - 2x

Set them equal to each other.

30 - x = 45 - 2x

Evaluate.

30 - x = 45 - 2x

-15 = -x

15 = x

hope this helps :)

The three angles in a triangle are in the ratio 3:5:7. Find the largest angle in the triangle?
Rzqust [24]

Answer: The largest angle is 7x

Step-by-step explanation:

Their sum is 180, so

3x + 5x + 7x = 180

5x = 180 --> x = 12

The largest angle is 7x, which is 7(12) = 84
