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:B

Step-by-step explanation: I said that because you have 27 and 50 Cent so basically you won't have that $5 in that picture because you still going to have that $0.04 and then you still have to have that much so I I think I am right but if I'm not I'm so sorry but I'm taking not even to get I'm trying to get back on track but I think is b for a reason like I think you could be because you have 27 and 50 Cent so if you got twenty-seven fifty cents you just rounding it down

Danielle’s aunt is 8 years than 3 times Danielle’s age. Her aunt is 34. Write an equation that relates Danielle’s age, a, to her
OverLord2011 [107]

Answer:

*Assuming that the question should read '8 years less than 3 times Danielle's age'*

Equation:  3a - 8 = 34, where 'a' = Danielle's age

Danielle's age (a) = 14

Step-by-step explanation:

Using key words and phrases from the problem, we can find Danielle's age by setting up an equation to solve for 'a'.  

Since Danielle's aunt is '8 years less than 3 times Danielle's age' her aunt's age can be written as:  3a - 8.  We also know her aunt is 34.  So, the equation becomes:

3a - 8 = 34

Add 8 to both sides:  3a - 8 + 8 = 34 + 8 or 3a = 42

Divide both sides by 3:  3a/3 = 42/3

Solve for a:  a = 14, so Danielle's age is 14 years old.
