12x─ 15 = 6 ─ 3x answered as a fraction

x is equal to one and two fifths.

Step-by-step explanation:

Given:

12x - 15 = 6 - 3x

Let's start by noticing that every term in that equation is divisible by 3.  That means we can factor 3 out of it, giving us:

4x - 5 = 2 - x

Now we'll add x to both sides:

4x + x - 5 = 2 - x + x

5x - 5 = 2

An then we add 5 to both sides:

5x - 5 + 5 = 2 + 5

5x = 7

Finally, we can divide both sides by 5 to get the final

5x ÷ 5 = 7 ÷ 5

x = 7/5

To put that in proper form it would be:

#15. square

step-by-step explanation:

because quadrilatural (idk how to spell it) means somthing that is not 3d or like, equal sides (or somthing like that   you know what i meanz)

hope this halps!

bai!

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
