That’s not enough information to say how long he could do it. He could go slower or faster than her but by how much if so. So it’s not enough info.
Answer:
3/10
Step-by-step explanation:
75(2)+.20x=238
You then solve for x by multiplying 75 by 2 to get 150. Then subtract 150 from both sides of the equation, so this is what you get .20x=88. Finally divide by .20 on both sides to get x= 440
Answer:
13, 14, 15, 16
Step-by-step explanation:
Call the first number n. Then the next three consecutive numbers (assuming integers) are n + 1, n + 2, n + 3.
The mean is the total of the numbers divided by how many there are.
Simplify and multiply by 4.
The first number is 13.
The median is 14.5, halfway between the "middle" numbers 14 and 15. This is just a check; no additional equation is necessary.
Answer:
parallel line slop2 = -5/4
perpendicular line slope = 4/5
Step-by-step explanation:
If 2 lines are parallel, they will have equal slopes.
Therefore, the slope of a line parallel to y = 1/4 - 5/4 x will be -5/4
If 2 lines are perpendicular, their slopes are negative reciprocals of each other. So the slope of the perpendicular line = -1 ÷ -5/4 = 4/5
