Answer:
( 
,
)
Step-by-step explanation:
The equation of a midpoint is as follows:
The x-coordinate:
x1 = 7, x2 = -8
7+(-8) = -1
Divide by 2 to get the x-midpoint
-1/2
The y-coordinate
y1 = -4, y2 = -5
-4 + (-5) = -9
Divide by 2 to get the y-midpoint
-9/2
You get:

Answer: Rate > 12 miles/day
x > 12
She must run more than 12 miles each day
Mona wants to run more than 60 miles this week. She ran a total of 24 miles during the first 4 days of the week. Which number line represents the number of miles Mona must run each day if she wants to meet her goal?
answer choices
x ≥ 10
x = 12
x > 10
x > 12
Step-by-step explanation:
To complete more than 60 miles a week.
After running 24 miles during the first 4 days
We are left with (7-4) days = 3 days
And also,
(60-24) miles to complete the weekly target
> 36 miles (more than 36miles)
Therefore, the number of miles needed to cover per day in the next 3 days is given as.
Rate > distance/time
Rate > 36miles/3days
Rate > 12 miles/day
OK.... here we go....
The width is 8 less than the length, so that means: w = L - 8.
So, since the area of a rectangle is: A = L x W ...
Therefore, 48 = L(L - 8)...
48 = L^2 - 8L...
continuing from there .... you get width = 4 and length = 12
48 = 4 x 12 (and notice that the width is 8 less than the length)
