This is simple. Coordinate form is (x,y) so you would just plug in your values.

2(5)-(1)=11

10-1 does not equal 11, so no it is not a solution.

Substitute the x for 5 and the y for 1.

(2)(5) - (1) = 11
10 - 1 = 9
9 does not equal 11
So, (5,1) is not a solution.

podryga [215]

Answer:

Mike can stitch one shirt in 6 hours and in 1 hour he can stitch $\frac{1}{6}$ (0.167) shirts.

Step-by-step explanation:

Mike can stitch 7 shirts in 42 hours

to calculate the time that he takes to make 1 shirt, we have to divide 42 by 7.

He can stitch 1 shirt in = $\frac{42}{7}$ = 6 hours

Now we calculate the work done in one hour.

He can stitch in 1 hour = $\frac{1}{6}$ shirts or 0.167 shirts

Mike can stitch one shirt in 6 hours and in 1 hour he can stitch $\frac{1}{6}$ shirts.
