Step-by-step explanation:

Consecutive integer problems are often easier to work if you consider average values. Here, the middle of the 5 consecutive integers is their average, which is 50/5 = 10.

Answer: 82.5 - x = R sorry if I am wrong

Step-by-step explanation:

1. We know all the angles in a triangle add up to 180 degrees.

<em>180 = x + x + 15 + R</em>

2. Combine like terms

<em>180 = 2x + 15 + R</em>

3. Subtract 15 from both sides

<em>165 = 2x + R</em>

4. Divide both sides by 2

<em>82.5 = x + R</em>

5. Subtract x from both sides

<em>82.5 - x = R</em>

4y=-6x+2

y=-6/4x+2

y=-2/3x+2


Slope is -2/3, the number in front of x is the slope.
