Answer:
x=-6
Step-by-step explanation:
*instead of doing a bunch of subtraction make it +(-#) you'll see what i mean
3(x - 3) - (6x - 3) = 4(3)
first do distributive property and figure out the easy stuff:
3x+(-9)+(-6x)+3=12
then you add 3x and 6x while also adding 9+3
-3x+(-6)=12
add +6 to both sides
-3x=18
then divide by -3
x=-6
Added gallons: 23.50÷1.25=18.8
All of the gases: 5+18.8=23.8
now the total distance: 23.8*27=642.6≈643 miles.
I hope this helps!
Answer:
- octagon
- irregular polygon
- concave
Step-by-step explanation:
The figure has 8 sides that are each line segments joined at the ends. An 8-sided polygon is called an <em>octagon</em>. Though the sides are the same length, not all angles are congruent, so the polygon is <em>not a regular polygon</em>. Some of the angles are reflex angles, so the polygon is <em>concave</em>, not convex.
