Z=1 because if we plug it in we get 1/5(3+2(1))-4(1)=-3 and then that goes to 1/5(5)-4 = -3 then 1-4=-3 and that is true

Answer:

A) z=1

Step-by-step explanation:

1/5(3+2z)-4z=-3

3/5+2/5z-4z=-3

2/5z-20/5z=-3-3/5

-18/5z=-15/5-3/5

-18/5z=-18/5

z=(-18/5)/(-18/5)

z=1

The length of a train car is 50.6 feet this is baffling 8 feet less than six times the width what is the width
hram777 [196]

Answer:

the width is 9 23/30 feet ≈ 9.767 ft

Step-by-step explanation:

Let w represent the width of the train car. Then 6 times the width is 6w, and 8 ft less than that is (6w-8). We are told this amount is 50.6 feet, so we have ...

6w -8 = 50.6

6w = 58.6 . . . . . . . add 8; next divide by 6

58.6/6 = w = 586/60 = 293/30 = 9 23/30 . . . . feet

This is a repeating decimal: 9.766666...

The width of the train car is 9 23/30 ft, about 9.77 ft.

Sean tried to drink as fast as he could. He drank the slushy at a constant rate. There were originally 275 milliliters of slushy
Artist 52 [7]

The rate at which Sean drank the slushy is 5 milliliters  per second.

The time it would take to drink all the slushy is 55 seconds.

<h3>How fast did Sean drink?</h3>

In order to determine the speed at which the slushy was drank, divide the slushy drank in 13 seconds by 13 seconds.

Speed = slushy drank in 13 seconds / time

(275 - 210) / 13

65 / 13 = 5 milliliters  per second

Time it would take to drink all the slushy =total milliliters of the slushy / speed

275 / 5 = 55 seconds.
