What is x? 5x - 7 + 3x - 10 = -2x - 5 + 7x - 13

x = -1/3

Step-by-step explanation:

5x - 7 + 3x - 10 = -2x - 5 + 7x - 13 add all like terms

8x-17=5x-18 put all variables on the left and the others on the right and symplify

3x = -1 divide

3x/3 and -1/3 equals x = -1/3

215.92 dollars is the answer

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
