Need help also if you can can you do it step-by-step explanation please thank you 3(c + 8) = 28<br>​
skelet666 [1.2K]

Answer:

c = 4/3

Step-by-step explanation:

3(c + 8) = 28

Since we have paranthesis, first use the dsitributive property [multiply 3 by c and 8]

3(c + 8) = 28

3c + 24 = 28

To find the value of c, you must have c alone on one side, so subtract 24 from both sides

3c + 24 = 28

3c = 4

Now, divide by 3 to both sides to get your answer

3c = 4

c = 4/3

Therefore, the answer is 4/3!

I hope this helps! :)

HELP PLEASE HOW DO I DO THIS. SHOW WORK PLEASE
kozerog [31]
Ok don't panic!!!

First you look and see that 3 dozen is 36 and you need 720 cookies so that every person gets 2 cookies. so you first need to multiply 36 by 10 to get 360 then multiply that by 2. 

So, in conclusion multipy each of the ingredients by 20! :)

17/16 x 20 = 340/16 of butter
5/8 x 20 = 100/8 of white sugar
7/4 x 20 = 140/4 of vanilla extract
15/8 x 20 = 300/8 of flour
5/6 x 20 = 100/6 of almonds
7/12 x 20 = 140/12 of confectioner's sugar
