Answer:
x = 7
Step-by-step explanation:
The integer values of x that satisfy |x| < 9 are ...
{-8, -7, -6, -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7. 8}
Of these values, the only one listed as an answer choice is ...
x = 7

<em>Additional comment</em>
The expression |x| means "the absolute value of x". It is the value of x with the sign made positive. That is |-10| = 10, a number greater than 9. Of course, |13| = 13, also a number greater than 9.
The d=rt formula is used in this situation where d=distance, r= speed, and t= time.
So plug in your variables and numbers to get;
distance=400*h
Hope this helps.
Answer:
140
Step-by-step explanation:
Angle 4 is congruent to angle 2 by corresponding angles postulate. Therefore, angle 2 is also 40. Angle 2 and angle 3 are supplementary, or add up to 180 because they are on a straight line. 140 and 40 add up to 180 so angle 3=140 degrees
