Supplementary angles

x+20+5x+10=180

6x+30=180

6x=150

x=25

**Answer:**

y=−4/3x+10

**Step-by-step explanation:**

Find the negative reciprocal of the slope of the original line and use the slope-intercept form y=mx+b to find the line perpendicular to 3x−4y=−2.

8 goes into 13 1 time. 13-8=5. Bring down the 2. 8 goes into 52 6 times. 52-48=4. Answer is 16 remainder 4.

Check: 16x8=128, +4 remainder equals 132.

WEW can use a simple equation to solve this

Let x be the number of kilometers she hiked in the morning . Then

x - 0.25x = 6 (Note 0.25 = 25 %)

0.75x = 6

x = 6 / 0.75 = 8 kilometers answer
