Answer:
np
Step-by-step explanation:
3.14(rs + r2)
3.14 (r= 2 x s= 3 + r =2 x 2)
3.14 ( 6+4)
3.14 (10)
3.14 x 10 = 31.4 units ² I guess
$30 + $30 = $60
$60 + $30 = $90
To pay back his sister the $80 he will to deposit money into his account for 3 weeks.
Since Steven would have $10 left over in his account from paying his sister all he needs now is $570.
You need to divide:
$570/$30 = 19
So Steven will need to deposit $30 into his bank account for 19 weeks to be able to buy the $580 bicycle.
Hope this Helps!!
Answer:
B) -3
Step-by-step explanation:
1. First you have to write the equation in slope intercept form. To do that, you must have y be alone on one side.
2. move the 3x to the right side with the 5 by subtracting 3x from both sides. Since 3x will cancel on the left, y will be left alone. 
3. Now that you're in slope intercept form, you can find the slope easily. The slope will always be the number in front of x. In this case, the number in front of x is -3. Therefore, -3 is your slope!
