10. 4 + 5x < 54
- subtract 4 to the right
- divide both sides by 5
answer: x < 10
11. 2(x + 4) + 3 = 6 - x
- distribute 2 to x and 4
- add 8 and 3
- add -x to left side
- subtract 11 to right side
- divide both sides by 3
answer: x = -5/3

Answer:
slope intercept form- y=mx+b
m=slope
b=y-intercept
how to find slope= rise/run
how to fine y-intercept= go straight down the y axis (up and down in the center of the graph) until you come across a point
slope=3
y-intercept=-1
answer= 3x-1

Explanation
Step 1
the sum of the internal angles in a triangle equals 18o, so

Step 2
now, replace the value of x in angle Q to find it

I hope this helps you
