Naomi and claire are painting a mural. naomi paints 2 square feet per hour and has already painted 16.5 square feet. claire paints 4 square feet per hour and has already painted 7.5 square feet. how many more hours will it take for naomi and claire to paint an equal total number of square feet? all i need to know is the equation

Step-by-step explanation:

Let's call hours.

So, Naomi paints at a rate of which means 2 square feet per hour. Additionally, we know that she already painted 16.5 square feet. All this is expressed as

On the other hand, Claire paints at a rate of , that is, 4 square feet per hour. She already painted 7.5 square feet. All this can be expressed as

If we want to find the time where the paint an equal number of square feet, we just need to make then equal, that is

Then, we solve for

Therefore, after four and a half hours, they will paint the same amount of area.

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
