Answer:3/2
how i did this
Add 11 to both sides.
4x=5+1
Simplify 5+15+1 to 66.
4x=6
Divide both sides by 4
x= 6/4
Simplify 6/4 to 3/2
Awnser
x=3/2
Sorry if not helpful just trying my best :)
Answer:
The answer is 75 miles per hour
Step-by-step explanation:
225÷3=75 ( how many times 3 go into 225)
We can check to see if this answer is correct by multiplying 75 by 3 ( multiply 75 three times)
75×3=225
There for 75 is the correct answer
(I hope this helped you answer your question. If you want to check if I'm correct you can use a calculator! Have a wonderful day!)

<h3>Perpindicular line are lines that intersect at a 90 degree angle.</h3><h3>Hope this helps!</h3>
U can either look at ur graph...and where the line crosses the x axis is ur x intercept...which is (-3,0)
OR
take ur equation and sub in 0 for y, and solve for x, ur x intercept.
2x - y = -6
2x - 0 = -6
2x = -6
x = -6/2
x = -3.....so ur x intercept is (-3,0)
