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>

hope this helps...
-1/2(-3/2x + 6x + 1) - 3
Simplify.
(3/4x - 3x - 1/2) - 3
Get rid of the parenthesis.
3/4x - 3x - 1/2 - 3
Add like terms.
(3/4x - 3x) + (-1/2 - 3)
Simplify.
-2 1/4x + (-3 1/2)
Get rid of the parenthesis.
-2 1/4x - 3 1/2
Hope I helped! :)
