Answer:
D
Step-by-step explanation:
there are 9 digits.
and round it off to the nearest hundred million which is 3.
There are 8 digits before the 3... so 10 gets to the power of 8.___ 10⁸
3,0×10⁸ m.s^-1
D is the correct answer I think.
Answer:
The answer to 17 is -8. 2+ = 10 - 12 = -2*4 = -8.
The answer to 18 is 28. 4^2 = 16, 7 + 1 = 9 + 3 = 12, 16 + 12 = 28.

Answer:
the solutions are {-2, 3}
Step-by-step explanation:
First combine the constants 2 and 17:
3|2x-1|+2=17 => 3|2x - 1| = 15
Next, divide both sides by 3. We get:
3|2x - 1| = 15 => |2x - 1| = 5
We want to solve for x, so divide all three terms by 2 as follows:
|x - 1/2| = 5/2
This equation has two solutions. We regard 1/2 as the "center." The equation tells us that x is either 5/2 greater than this 1/2 or 5/2 smaller:
x = 1/2 + 5/2 = 6/2, or x = 3
and:
x = 1/2 - 5/2 = -4/2 = -2
Thus, the solutions are {-2, 3}
