He has 30 and gets rid of 4 so 26 cookies then gets rid of 8 more, so then 18 cookies left.
ROC is often used when speaking about momentum, and it can generally be expressed as a ratio between a change in one variable relative to a corresponding change in another; graphically, the rate of change is represented by the slope of a line.
Hello!
By using a certain formula, a repeating number with two repeating digits will always become the number out of 99. In our case, we would get 
.
To get the numerator to equal three, we divide both sides by 9.
Therefore, x=11.
I hope this helps!
Alright, to get 1% of his unpaid balance, we can make 1% = 0.01 by moving the decimal place 2 places over. Multiplying 0.01 by 2365 gets 1% of your unpaid balance=23.65. Since we have to add 15 as a base value, we have
15+23.65=38.65
Answer:
Length-65 ft Width: 85
Step-by-step explanation:
Let's set the length as x, and the width as x+20 (because it is 20 ft longer than length)
We know that 2L+2W=Perimeter
We can substitute x and x+20 in for 2L and 2W, and 300 for Perimeter
New Equation: 2(x) +2(x+20)=300
After Distribution: 2x+2x+40=300
Combine like terms: 4x+40=300
Subtract 40 from both sides: 4x=260
Divide 4 on both sides and you get x=65 (Length)
Add 20 to get width : x+20= 85
I hope it helped! :)
