Answer:
6
Step-by-step explanation:
-4x -3 = -6x +9
-4x = -6x +12
2X = 12
x = 6
Answer: The LCM of 8, 9, and 19 is 1,368.
Prime factorization of the numbers:
8 = 2 x 2 x 2
9 = 3 x 3
19 = 19
2 x 2 x 2 x 3 x 3 x 19 = 1,368.
Hope this helps! Have a great day!
Answer:
252°
Step-by-step explanation:
In the figure attached, the diagram is shown. There, we can see that
∠DOB = ∠AOD + ∠AOC + ∠COB
Replacing with the equivalences: ∠DOB has a measure of 3.5y, the measure of ∠AOD is y, and ∠AOC + ∠COB measure 180°, we get:
3.5y = y + 180°
3.5y - y = 180°
2.5y = 180°
y = 180°/2.5
y = 72°
Therefore, ∠DOB = 3.5*72° = 252°
4 mph is a rate, and is represented by a straight line thru the origin with slope 4/1.
Draw a set of coordinate axes and label them t (for time) and d(for distance).
Start with your pencil point at the origin. Arbitrarily move this point 3 spaces to the right, and from there move it 4 spaces up. You'll be at (3,4).
Draw a straight line from the origin (0,0) to the point (3,4).
