Answer:
112 hours and 50 mins
Step-by-step explanation:
Numbers of mins worked in a day = 7×60+30 =450 mins
Now number of mins worked in 15 days = 450×15
= 6750 mins
to convert mins into hours divide by 60
6750÷60 = 112.50
that means total number of hours worked in 15 days = 112 hours and 50 mins

Answer:
(1, 2) is a solution to this system of equations
Step-by-step explanation:
Plug in (1, 2) into each equation
17x + y = 19
17(1) + 2 = 19
17 + 2 = 19
19 = 19 ----------->YES
8x + 5y = 18
8(1) + 5(2) = 18
8 + 10 = 18
18 = 18 ------------------->YES
Answer:
(1, 2) is a solution to this system of equations
