Step-by-step explanation:
Y=kx+b
If m=1/k
Y=-5/3x+b
I don't know what your m means
So I can only write like this.
Answer:
25 Nickles
Step-by-step explanation:
n + q = 38
0.05n + 0.25q = 4.50
n + q = 38
q = 38 - n
0.05n + 0.25q = 4.50
0.05n + 0.25(38 - n) = 4.50
0.05n + 9.5 - 0.25n = 4.50
-0.2n + 9.5 = 4.50
-0.2n = 4.50 - 9.50
-0.2n = -5
-0.2n/0.2 = -5/0.2
-n = -25
-n/-1 = -25
n = 25

Answer:
width - 5cm
length - 10cm
Step-by-step explanation:
Let's define the variable w as the width of the rectangle. The length of the rectangle would be 2w as given by the problem. A form of the perimeter of a rectangle formula is:
P = 2(l + w)
Where P is the perimeter, l is the length, and w is the width. We substitute our length, width, and perimeter to get:
30 = 2(2w + w)
You can simplify to get:
30 = 2(3w)
and divide by 6 on both sides to isolate w:
w = 5cm - the width is 5 cm
The length is twice the width, and 2 x 5 is 10, so 10cm is the length.
