6. Mark has $1000 in a savings account and withdraws $55 per week. Patricia has $800 in savings and withdraws $30 each week. Mark wants to know how many weeks it will take for him and Patricia to have the
same amount of money in their savings accounts.

Hey there! I'm happy to help!

Let's call the number of weeks w. Since we want their balances, to be equal, we can create an equation.

1000-55w=800-30w

Now we solve for w. We add 30w to both sides.

1000-25w=800

Subtract 1000 from both sides.

-25w=-200

Divide both sides by -25.

w=8

Therefore, Mark and Patricia will have the same amount of money in their savings accounts after 8 weeks.

Have a wonderful day! :D

step-by-step explanation:

b and c

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
