One Solution<br><br> 6x – 3x + 4 – 2x =

emmainna [20.7K]

Answer:

x+4

Step-by-step explanation:

What I like to do in these types of problems is to separate the terms with a variable and those without.

So move +4 to the very end of the problem to make it look like this:

6x-3x-2x+4

Now simply subtract! After subtracting the first two terms (6x and -3x) it should look like this:

3x-2x+4

Then subtract once more (3x-2x)!

x+4

This cannot be simplified anymore so x+4 should be your final answer!

Petra was given 12 yards of fabric to make costumes for the school play if each costume requires 1 1/2 yards how many costumes c

solmaris [256]

Petra can make 8 costumes with 12 yards of fabric

<h3><u>Solution:</u></h3>

Given that Petra was given 12 yards of fabric to make costumes for the school play

Each costume requires $1\frac{1}{2}$ yards

<em><u>To find: number of costume Petra can make</u></em>

The number of costume Petra can make is calculated by dividing the total fabric she has by fabric needed for one costume

$\text {number of costume Petra can make }=\frac{\text {total fabric she has }}{\text {fabric needed for one costume }}$

Total fabric she has = 12 yards

Fabric needed for 1 costume = $1\frac{1}{2} = \frac{2 \times 1 + 1}{2} = \frac{3}{2}$ yards

Therefore,

$\text {number of costume Petra can make }=\frac{12}{3 / 2}=\frac{12}{3} \times 2=8$

Thus petra can make 8 costumes with 12 yards of fabric
