Do you know the multiples of 10
Answer:
yards.
yards.
Step-by-step explanation:
We have been given that a square playground is surrounded by a sidewalk on all sides. The sidewalk is
yards long on each side of the park.
Since side walk is 0.5 yard wide, so each side of playground will be 0.5 less than each side of sidewalk.



Since playground is square, so perimeter of playground will be 4 times the length of each side of playground.

Upon distributing 4 we will get,

Therefore, perimeter of playground will be
yards or
yards.
I'm assuming you are finding the equation of the line of Line J
Slope-intercept form: y = mx + b
[m is the slope, b is the y-intercept or the y value when x = 0 --> (0, y) or the point where the line crosses through the y-axis]
For lines to be perpendicular, the slopes have to be negative reciprocals of each other. (basically changing the sign (+/-) and flipping the fraction/switching the numerator and the denominator)
For example:
slope = 2 or 
Perpendicular line's slope =
[changed sign from + to -, and flipped the fraction]
slope = 
Perpendicular line's slope =
[changed sign from - to +, and flipped the fraction]
Since you know the slope is 3, the perpendicular line's slope is
. Plug this into the equation
y = mx + b
To find b, plug in the point (3, 8)

8 = -1 + b Add 1 on both sides to get "b" by itself
8 + 1 = -1 + 1 + b
9 = b

Answer:
I'm pretty sure it b
Step-by-step explanation:
I think its b
