Recall your d = rt, distance = rate * time.
let's say the Eastbound train is going at a rate of "r" mph, since we know the Westbound train is going faster 12 miles more than that, then the Westbound train must be going "r+12".
we also know that after 4 hours, both of them were 760 miles apart, so
Answer:
X=11/2
Step-by-step explanation:
2x=8+3
2x=11
x=11/2
First, let's re-arrange to slope-intercept form.
x + 8y = 27
Subtract 'x' to both sides:
8y = -x + 27
Divide 8 to both sides:
y = -1/8x + 3.375
So the slope of this line is -1/8, to find the slope that is perpendicular to this, we multiply it by -1 and flip it. -1/8 * -1 = 1/8, flipping it will give us 8/1 or 8.
So the slope of the perpendicular line will be 8.
Now we can plug this into point-slope form along with the point given.
y - y1 = m(x - x1)
y - 5 = 8(x + 5)
y - 5 = 8x + 40
y = 8x + 45
Answer:
If Nancy only used the mean, then outliers could make her calculations inaccurate. By using an appropriate measure of center, Nancy is more likely to select clothing sizes that will fit the population of the countries she is sending clothing to.

Answer:
X = 76*4
= 304 cups of food
Step-by-step explanation:
Given:
- Monkey eat 4 cups of food / day
- Elephants eat 76 times as much as Monkey does / day
So Let X is the number of cups of food that elephants eat per day, we have the equation:
X = 76*4
= 304 cups of food
Hope it will find you well.
