Answer:

I'm not sure bout what to do so I did this instead.

Step-by-step explanation:

3x + 4x + 19 = 180

7x + 19 = 180

7x + 19 - 19 = 180 - 19

7x = 161

7x ÷ 7 = 161 ÷ 7

x = 23

_________________________

3x + 4x + 19 = 180

3(23) + 4(23) + 19 = 180

69 + 92 + 19 = 180

180 = 180

________________________

3x = ?

3(23) = ?

69 = ?

__________________________

4x + 19 = ?

4(23) + 19 = ?

92 + 19 = ?

111 = ?

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.
