If 6x – 10y
9 is a true equation, what would be the value of -18x + 30y?

The value of -18x + 30y is -27

Step-by-step explanation:

Algebraic Expressions

It's given that:

6x - 10y = 9

We are required to find the value of

-18x + 30y

The easiest way to solve the problem is to visualize that:

-18x = -3(6x)

30y = -3(-10y)

This means that the second expression is equal to the first expression multiplied by -3, thus:

-18x + 30y = -3(6x - 10y) = -3*9 = -27

The value of -18x + 30y is -27

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
