Answer:

12x+4

Step-by-step explanation:

We can solve this by using PEMDAS (parentheses exponents multiplication division addition subtraction) to solve this in the correct order:

4+8÷2x (6-3)

So first we solve (6-3) since it’s in parentheses:

4+8÷2x (3)

Now we multiply 3 times 8/2x:

4+8/2x(3)

4+12x

(Put in order)

12x+4

And that^ is the answer because we cannot simplify any further!

Hope this helps :)

Only answer this if you know 1000% it is correct I need this to be correct

Serggg [28]

I believe that the answer would be B because if you put the numbers into the variable spots, this is what you get. For example, when you put -3 into A, because it is the one with the x, and 6 in for B, you would get the first part of the equation. Then, put 12 in for C, you would get the whole equation. Sorry if this is wrong or if I did a bad job explaining this. Good luck!

A dress maker had 27 yards of fabric.If she wanted to use the fabric to make 5 dresses,each using the same amount of fabric how

Alina [70]

Each dress will need 5.4 yards of fabric and the answer lies between 5 and 6

Step-by-step explanation:

Given

Total fabric = 27 yards

Dresses to be made = 5

In order to find the measurement of fabric for one dress, the total fabric will be divided by number of dresses to be made.

So,

$Fabric\ for\ one\ dress = \frac{Total\ fabric}{No.\ of\ dresses}$
