Let's solve this step by step.

Layout equation

4v-3(1+6v)=81

Step 1: Solve parenthesis.

4v-3-18v=81

Step 2: Get rid of 3.

4v-3-18v=81

   +3          +3

4v-18v=84

Step 3: Solve the 'v'.

-14v=84

Step 4: Divide -14v by -14 and 84 by -14.

-14v/-14=84/-14

So the answer is v=-6.

Expand and simplify it. Remember the distributive property? a(b+c)=ab+bc
4v-3-18v=81
-14v=84
v=-6

Kate bought 4 cans of soup for $2.67. How much would it cost for her to buy 10 cans?
gavmur [86]

Answer:

It would be 6.60

Step-by-step explanation:

first you have to find the price of one can, so you divided 2.67 by 4.

the answer would actually be 0.6675, but you have to stop at the tenths place for money, so in this case, it would be 0.66.

we multiply 0.66 by 10 and get 6.6 which is also 6.60

It would cost $6.60 to but 10 cans.

Idk if this helps, but I hope it does.
