Mira picked two numbers from a bowl. the difference of the two numbers was 4, and the sum of one-half of each number
was 18. the system that represents mira's numbers is below.
x - y = 4
3x + y = 18
which two numbers did mira pick?

multiply  1/2x - 1/2 y = 4 by 2,,  we get x - y = 8

x   - y =   8   and  

x  + y = 18                  Adding these 2 equations:-

2x = 26  

x = 13

and y =  18-13 = 5

Mira picked the numbers 13 and 5.

x/3-10=8

x/3=18

x=48

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
