Answer: Choice D. 15 - (-18)
This results in 15 - (-18) = 15 + 18 = 33.
So from -18 to 15 on a number line is 33 spaces.
We can also say
|-18 - 15| = |-33| = 33
The use of absolute value is to ensure the distance is never negative.
<span>15x+12=45+4x </span>⇒15x - 4x = 45 - 12 ⇒ 11x = 33 ⇒ x = 3
A:B = 2:3
A=126
B=?
126/2=63
63x3=189
A=126
B=189
A:B = 126:189
Step-by-step explanation:
The sum must be irrational in contradiction to it being rational
