Landon has 15 fewer toy cars than his sister. If Landon has 84 toy cars, how many toy cars does his sister have?
84
69
99
100

99

Step-by-step explanation:

Because Landon has 15 fewer cars than his sister you have to add 15 cars onto 84 so his sister has 99.

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

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
