30 is the correct answer also I’ve downed coffee and monster
Answer:
The answer is 50 hours
Step-by-step explanation:
4x = 200
Divide both sides by 4
x = 200 \div 4 = 50
so after 50 hours of walking, the men will be 200 miles apart.
Answer:
the roots are {-4/3, 4/3}
Step-by-step explanation:
Begin the solution of 11=6|-2z| -5 by adding 5 to both sides:
11=6|-2z| -5 becomes 16 = 6|-2z|.
Dividing both sides by 12 yields
16/12 = |-z|
There are two cases here: first, that one in which z is positive and second the one in which z is negative.
If z is positive, 4/3 = -z, and so z = -4/3, and:
If z is negative, 4/3 = z
Thus the roots are {-4/3, 4/3}
