Step-by-step explanation:
Terminating decimals: these have a finite number of digits after the decimal point.
Example: 9.5
Recurring decimals: these have one or more repeating numbers or sequences of numbers after the decimal point, which continue infinitely.
Example: 0.333333...
D + t = total earnings
$3h + t = total earnings
$3h + $22 = total earnings
Fill in h as however many hours she is working.
Example: She worked for 8 hrs and got $22 in tips.
$3(8) + $22 = ?
$24 +$22 = $46
Answer:
160
Step-by-step explanation:
This is basically saying "8 is 5% of what number (total)"?
<u>Note:</u> 5% in decimal is 5/100 = 0.05
When translating a word statement into algebra, we need to note that "is" means "equal" and "of" means "multiplication".
Let's translate <u>"8 is 5% of what number (total)"</u> (letting total number of coins be n):
8 = 0.05 * n
<em>solving, gives us:</em>
<em>8 = 0.05*n</em>
<em>n = 8/0.05 = 160</em>
<em />
<em>Hence, total number of coins Mia has is 160</em>

Answer: (x+7)^2 + (y+2)^2 = 4</h3>
===========================================================
Explanation:
The center is at (h,k) = (-7,-2)
h = -7
k = -2
The radius is r = 2 units
Plug these three pieces of info into the template below and simplify
(x-h)^2 + (y-k)^2 = r^2
(x-(-7))^2 + (y-(-2))^2 = (2)^2
(x+7)^2 + (y+2)^2 = 4
You can use a tool like Desmos or GeoGebra to confirm the answer.
