Write an equation for the situation then solve for x. After paying $7 for a sandwich, John has $11. With how much money did he start? (I know the answer to the question but the steps on how to solve for x confuse me)

x = 18

Step-by-step explanation:

total money = money spent + money left

x = 7+11

x = 18

over the argument its not good to fight.

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
