Answer:
Width = 80 ft and length = 85 ft.
Step-by-step explanation:
Let the width be x ft then the length is x+5 ft.
width * length = area, so
x * (x + 5) = 6800
x^2 + 5x - 6800 = 0
( x - 80)(x + 85) = 0
x = 80, -85
We ignore the negative so x = 80 ft.
Width = 80 and length = 80+5 = 85 ft.

Step-by-step explanation:
Answer:
y=(-6/5)x+8.6
Step-by-step explanation:
If a line is perpendicular to 5x-6y=9, then it must have a slope that is the negative reciprocal.
1) Fine the slope of the first line by setting the equation equal to y.
5x-6y=9
5x-9= 6y
(5/6)x-1.5=y
slope= 5/6
2) Find the negative reciprocal of the slope
slope: 5/6
reciprocal: 6/5
negative reciprocal: -6/5
3) We now get to use the points (-3, 5) by plugging them into slope-intercept form. The goal is finding the y-intercept.
y=mx+b
5=(-6/5)(-3)+b
5=(-18/5)+b
5= -3.6+b
b= 8.6
4) Now we put everything back in slope-intercept form.
y=(-6/5)x+8.6
Answer:
d = 1.75 miles
Step-by-step explanation:
A track team ran 8 and 3/4 miles in 5 days.
We need to find the distance covered by it each day. Let the distance is d.
miles in 5 days
or
miles in 5 days.
So, each day the team will cover 1.75 miles.
