49 pairs of trousers = 49 × 57/1

= 2793 minutes

Hope this helps.

46 hours and 55 minutes

Step-by-step explanation:

If 57 minutes is required for 1 pair, to find how much time it will take to sew 49 pairs we simply multiply 57 by 49

After you do that you will be left with 2,793 minutes.

Since 60 minutes make an hour we divide the answer by 60.

2,793 ÷ 60 = 46 hours and 55 minutes.

I really hope this helps.

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
