Step-by-step explanation:
calculated the equation and the expanded form
Answer:
-8/3 or -2.66666 or -2 2/3
Step-by-step explanation:
Move constant (+9) to the right side and change its sign (25 - 9)
Then subtract those numbers (=16)
Divide both sides by -6
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>
