11 and 2. When you add them it equals 13. When you multiply it equals 22.
3x + 4y = -5
-3x -3x
4y= -3x -5
/4 /4
y= -3/4x-5/4
3x + 3y = -2
-3x -3x
3y = -3x-2
/3 /3
y= -1x-2/3
39/1.5 = 26 km per hour
51/3 = 17 km per hour
Then you need the mean. 26+17/2 = 21.5 km per hour
Siamone has $65.32 + DAN
Dan has CARLY - $37.50
CARLY = $127.75
Plug Carly into Dan's equation...
$127.75 - $37.50 = $90.20
DAN = $90.20
Plug Dan into Siamone's equation
$65.32 + $90.20 = $155.57
The formula for finding time is the distance divided by the velocity.So the answer is 100÷30=3.3333...
