11) you have $75 in savings and your brother has $120 in savings. if you saving $15 a week and your brother savings $6 a week. how long will it be before both of you have the same amount of money in savings?

5 weeks

Step-by-step explanation:

In order to solve for the amount of time it would take for both you and your brother to reach the same amount in savings, you need to set up an expression for each person.  You save $15 a week plus you start with $75, so:

You: 15x + 75

Your brother only saves $6 a week, but starts with $120, so:

Brother: 6x + 120

If 'x' is the number of weeks in both equations, we can set the expressions equal to each other to find out how many weeks until both of your accounts are equal:

15x + 75 = 6x + 120

Subtract '6x' from both sides: 15x - 6x + 75 = 6x + 120 - 6x or 9x + 75 = 120

Subtract '75' from both sides: 9x + 75 - 75 = 120 - 75 or 9x = 45

Divide and solve for x: 9x/9 = 45/9 or x = 5 weeks

24

step-by-step explanation:

if it takes 8 pounds to make 12 divide 12 by 8 and you get 1.5, 1.5 x 16 = 24

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
