Answer:

A: x/3 + 10   C:(3,015 * x) - 186   ( / means its a fraction)

Step-by-step explanation:

For A all your doing is 15/3 which gives u a whole of 5. Then your going to add the 10 to the 5. 10+5=15. For C, your going to divide 3,015 by 15. Then you will get 201. After you will subtract 201 - 186. Then your final answere will be 15. Hope this helped!

In a triangle, two angles have measures of 45 degrees and 85 degrees. What is the measure of the third angle in this triangle?
Blizzard [7]

Answer:

50 degrees

Step-by-step explanation:

All three angles in a triangle add up to 180 degrees. If you know the measure of two angles, add them together and subtract the sum from 180.  

45+85=130.  Then, subtract 130 from the total, or 180.   180-130=50. The measure of the third angle of the triangle is 50 degrees.

Darryl and Kayla sold pies for a school fundraiser. Darryl made $38 from 2 chocolate pies and 4 apple pies. Kayla made $138 from
REY [17]

Answer:

$3

Step-by-step explanation:

Let chocolate pie be x and apple pie be y

Darryl made $38 from 2 chocolate pies and 4 apple pies

That’s

2x + 4y = $38

Kayla made $138 from 14 chocolate pies and 12 apple pies

That’s

14x + 12y = $138

We now have two equations

Equation 1 : 2x + 4y = 38

Equation 2: 14x + 12y = 138

Multiply equation one by 12 and equation 2 by 4 to eliminate apple pie y

We have

12 x 2x + 12 x 4y = 12 x 38

4 x 14x + 4 x 12y = 4 x 138

24x + 48y = 456

56x + 48y = 552

Subtract equation equation two from one

-32x = -96

Divide both sides by -32

x = -96/-32

x = 3
