Answer:

w= -3

Step-by-step explanation:

To solve for w, we need to get w by itself. To solve, do the opposite of what is being done, and whatever is done to one side, needs to be done to the other.

30 = –6w + 12

First, subtract 12 from both sides, since it is being added

30-12= -6w +12-12

18= -6w

Divide both sides by -6, since it is being multiplied

18/-6= -6w/-6

The -6s on the right cancel, and we are left with

-3= w

6. Jessie sorted the coins in her bank. Shemade 7 stacks of 6 dimes and 8 stacksof 5 nickels. She then found 1 dime and1 nickel.
Leokris [45]
Lets write down the information that we know.

Jessie has 7 stacks of 6 dimes, so Jessie has a total of 6*7 dimes

Dimes=7*6=42dimes  

Jessie has 42 dimes, but then she found another one so lets add one more dime.

42+1=43 dimes

Jessie has 8 stacks of 5 nickels, so Jessie has 8*5 nickels

Nickels=8*5=40nickels

Jessie has 40 nickels, but then she found another one so lets add 1 to the total number of nickels.

40+1=41nickels

Now we can answer the question.

How many dimes and nickels does jessie have in all?

nickels+dimes=
41+43=84 coins

Jessie has 84 coins in total
