Multiply s on both sides

s(T/s - b/s) = 1(s)

T - b = s

Minchanka [31]

Since we know the x and y, you would divide 480 by 15 and 32 miles per hour. Then you would multiply 7.2 by 32 and get 230.4. Your trying to find with wind and against wind so just times that by two and get 460.8. I think

The post office will accept packages whose combined length and girth is at most 42 inches. (the girth is the perimeter/distance

Vilka [71]

If x represents the length of the box, then 42-x will be the girth. Since the largest area for a given girth is that of a square, the side length of the square cross section is (42 -x)/4.

The volume as a function of package length is then
.. v(x) = x((42-x)/4)^2
This has a maximum at x=14. The corresponding volume is 686 in^3.

Sam Is 11 years older than Susan the sum of their ages in years is 27 what’s sams age in years

sweet [91]

Answer:

Step-by-step explanation:

Let Sam be x

Let Susan be y

x = y+11

x + y = 27

Substitute (x) with (y+11)

(y+11) + y = 27

Solve the equation

2y + 11 = 27

2y = 16

y = 8

Susan's age is 8.

Sam's age is 8 + 11

Sam's age is 19

Hope this helped :)
