I can't help you if the table is not provided
28 + 18.25x = 161 -15x (here, x stands for every week this addition or withdrawal happens)
So:
28+18.25x = 161 - 15x
18.25x = 161 - 28 - 15x
18.25x = 133 - 15x
18.25x + 15x = 133
33.25x = 133
x = 133/33.25
x = 4
So, they will have the same balance in 4 weeks.
Answer:
We can convert the mixed fraction into an improper fraction:
4 1/2 → 9/2
Now we divide by 7, since there are 7 days in a week:
9/2 ÷ 7
When we divide, by a number, it can be placed in the denominator:
9/2*7 = 9/14
There's no other way to simplify it, so that's our final answer.
Step-by-step explanation:
slope intercept form
y= mx+b
3x+y =7
subtract 3x from each side
y = -3x+7
