Answer:

(0,-7)

Step-by-step explanation:

4x - y = 7

-y = -4x + 7

y = 4x - 7

-4x + (4x - 7) = -7

-4x + 4x - 7 = -7

x = 0

4(0) - y = 7

-y = 7

y = -7

It takes Bruce 12 h to complete his training. It takes Oliver approximately 2 days, 2 h, and 15 min to complete
Stolb23 [73]

Answer:

Oliver completed his training work in 50.25 hours

Step-by-step explanation:

we know that

1 day= 24 hours

1 hour=60 minutes

we have

2 days, 2 h, and 15 min

<u><em>Convert days to hours</em></u>

2 days=2(24)=48 hours

<u><em>Convert minutes to hour</em></u>

15 min=15(1/60)=1/4=0.25 h

so

2 days, 2 h, and 15 min=(48)+(2)+(0.25)=50.25 h

therefore

Oliver completed his training work in 50.25 hours

Answer:

See below

Step-by-step explanation:

11 box 1: 12

11 box 2: 101

12 box 1: 80

12 box 2: 80

12 box 3: 80

13 box 1: 16

13 box 2: 16

13 box 3: 76


20 = y + 12

20 - 12 = y + 12 - 12

8 = y


x + 2 = 19

x + 2 - 2 = 19 - 2

x = 17


z - 313 = 176

z - 313 + 313 = 176 + 313

z = 489
