Neither...
205/1000 equals .205
So they are both the same.
Hope this helps -J
We can say L as length and W as the width
L= 3w + 8
The formula for perimeter is 2L + 2W = P. We can substitute L in as "3w+8" to make the equation...
2(3w+8)+2w=88 Now, we can simplify by distributing the 2 to each term
6w+16+2w=88
8w+16=88 Then subtract 16 from each side..
8w=72
w=9
So the width is 9, so we can substitue that into the previous equation, L = 3w+8.
L=3(9)+8
L=27+8
L=35, W=9

y=2×2+3×-1 and x+ y= -1
Step-by-step explanation:
y =2×2+3x-1and x + y =1y= -2×2+3x-7 and x+y=-2x3x-1and x+y =-1
Answer: See explanation
Step-by-step explanation:
Point slope form: y - y₁ = m (x - x₁)
y₁ = 6
x₁ = -7
y - 6 = -1 (x - [-7])
y - 6 = -1 (x + 7)
y - 6 = -1x - 7
Add 6 to both sides
y = -1x - 1 <em>or </em>y = -x -1
Slope intercept form: y = mx + b
m = -1
b = 6
y = -1x + 6 <em>or </em>y = -x + 6
Standard form: Ax + By = C
Change slope intercept form into _x + _y = c
Slope intercept form: y = -x + 6
Standard form:
y = -x + 6
Add x to both sides
x + y = 6 <em>or </em>-x - y = -6
