X is the number
sum means add
sum of half a number and 4 means
(x/2)+4
result is -16
(x/2)+4=-16
minus 4 both sides
x/2=-20
times 2 both sides
x=-40
the number is -40
Answer:
D
Step-by-step explanation:
to determine the relationship between these two lines you have to find the slope.
=> if they have the same slope ,then they are parallel.
=> if they have negative inverse slope relative to each other ,then they are perpendicular.
=> if the slope for both equations is neither of the above cases ,then the two equations are neither parallel nor perpendicular.
so if we divide the first equation by 3 which is the commen factor for the whole equation and arrange it in the form y=mx +b it would give us y =5x +4. and since the two have the same slope which is 5 ,then we can conclude they are <u>parallel lines.</u>

Marcus needs to bike at least 11 miles each day.
Step-by-step explanation:
Given,
Distance to cover = 80 miles at least
Distance already biked = 25 miles
Number of days left = 5
Let,
x be the distance to cover in 5 days.
According to given statement;
Number of days left * Distance to cover + distance already bike ≥ Total distance to travel
Dividing both sides by 5
Marcus needs to bike at least 11 miles each day.
