The original number is 15.
Let’s work it out.
First, divide.
21 divided by 3 is 7.
Now, add.
8 + 7 = 15
This is true because...
15 - 8 = 7
Hope this helps, have a great day, stay safe and positive.

Answer:
y=-4x+6
Step-by-step explanation:
what you have to do for this problem you have take the point 1,2 slide it over to the left one since the slope is negative and up 4 then you do that till you cross the y axis, but in this case you only have to do it once
Let
x--------> the border’s length
y--------> the border’s width
P--------> perimeter of the border
we know that
x=5+y------> equation 1
P=2*[x+y]-----> P=2x+2y
P <=180 ft
(2x+2y) <= 180-------> equation 2
substitute the equation 1 in equation 2
2*[5+y]+2y <= 180
10+2y+2y <= 180
4y <= 180-10
4y <=170
y <=42.5 ft
so
the maximum value of the width is 42.5 ft
for y=42.5 ft
x=42.5+5------> x=47.5 ft
the answer is
the width of the border is less than or equal to 42.5 ft
Profit is calculated by subtracting the expenses from the income. So:
p = i - e
With a 20 ft leash, the dog can move in the circle. Now, knowing that he can move around in a circle, we just need to use the circle formula. A = 3.14(r) squared.
Since you use 3.14 for pi; A = 3.14(20) squared --> A = 1256
Answer = 1256
