Answer:

Step-by-step explanation:
If the speed is constant for 5 machines and produces x amount of toys we know that rate is defined as a constant per time:
Here the machines are constant and the rate is x toys per hour:
If 5 machines make x per hour:
Rate is x/1 hour
The the ratio of 8/5 is 1.6. Therefore for 8 machines the rate is 1.6 times more per hour than for5 machines. Therefore we can write an expression as:
Rate for 5 machines is x and for 8 machines is y:

Answer: x =
Step-by-step explanation:
-3x -2y = 10 Get x alone by add 2y to both sides
+2y +2y
-3x = 10 + 2y Divide both sides by -3
x = -10/3 - 2y/3
