The answer is 14 because you just have to pick a number to work with so it is 14.
Answer:
7th week
Step-by-step explanation:
Let us represent the number of weeks as x
Jill begins the summer with $500 in her savings account. Each week, she withdraws $20.
$500 - $20× x
500 - 20x
Her brother, Sam,starts the summer with $150 in his account. He adds $30 to his account each week.
$150 + $30 × x
150 + 30x
At what week will both Jill and Sam have the same amount in their account?
We solve this be Equating both Equations together
Jill = Sam
500 - 20x = 150 + 30x
Collect like terms
500 - 150 = 30x + 20x
350 = 50x
Divide both sides by 50
50x/50 = 350/50
x = 7 weeks
Therefore, at the 7 week, Jill and sam would have the same amount in their accounts
430,825 because if you add them up you get this
The line passes through 
and 
. We can compute the slope as
<u>1.5</u> cm <u>x </u> cm
5 km 30 km
cross multiply and divide-
1.5 x 30 = 5x
45 = 5x
divide each side by 5
x = 9 cm
