At the start of the month, Stephen’s savings account had a balance of $1,624. He made a $420 withdrawal each week for four weeks. During that month, he also made two deposits of $600 each and one deposit of $1,000. What was the balance in Stephen’s account at the end of the month?

$2,144

Step-by-step explanation:

1. Add up all the deposits and the savings account: 1,624+600+600+1,000=3,824

2. Multiply 420 by 4 because he spent $420 each week for 4 weeks: 420x4=1,680

3. Subtract 1,680 from 3,824 to find out how much money he has left. 3,824-1680=2,144.

So Stephen's balance is $2,144 at the end of the month.

10

step-by-step explanation:

7+3=10

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
