Answer:

x = 12.1

Step-by-step explanation:

20 − (z + 7) = 0.9

Distribute the minus sign

20 -x -7 = .9

Combine like terms

13 -x = .9

Subtract 13 from each side

-x = -12.1

x = 12.1

Answer:

20 - (z + 7 ) = 0.9

20 - z - 7 = 0.9

13 - z = 0.9

- z = 0.9 - 13

-z = - 12.1

Divide both sides by -1

z = 12.1

Hope this helps.

A state offers two lottery games, WinOne and PlayBall. Both games cost $2 per ticket.
uysha [10]
In this question, both tickets cost 2$ per ticket.
The answer to this question would be: $0

In WinOne scenario, you need to match a ticket that has to pick from A-J(10 possibilities) and 0-9 (10 possibilities). The chance to win would be: 1/10* 1/10= 1/100

The expected value must be:
E= chance to win * win amount - ticket price
E= 1//100*$200 - $2= $2-$2= 0

A weed call the raindrop vine is known for growing at a very fast rate. it can grow up to 0.75 feet per day. How fast in inches
xxMikexx [17]

First we need to convert 0.75 feet to inches.

0.75 feet = 9 inches

Now we need to divide 9 inches by 24 hours.

9/24 = 0.375

This means that each hour, the vine grows 0.375 inches.
