Answer:

7 CDs has been purchased.

Step-by-step explanation:

Given,

For the first CD, cost = $ 14.00,

Let x be the additional number of CD purchased by Maria,

That is, total purchased CD = x + 1,

Now,  for each additional CD, cost = $ 12.00,

So, the cost of x additional CD's = 12x dollars,

And, the total amount of the CDs = (14 + 12x) dollars

According to the question,

Total cost = $ 86.00

⇒ 14 + 12x = 86

⇒ 12x = 86 - 14 = 72

⇒ x = \frac{72}{12} = 6

Hence, the total number of CDs purchased = 6 + 1 = 7.

Can anyone help me with this proportion ,please?? I'm having a really hard time trying to solve it

Answer:

320 pound

Step-by-step explanation:

Ratio is decently easy after u understand the concept

So... This is what the question gave

Jupitar : earth

8 : 3

In other words, if u weigh 8 pound on Jupitar, u would weigh 3 pounds on earth

Therefore now they say on earth, the person weighs 120 pound, so let's just put in this value

Jupitar : earth

8 : 3

? : 120

Now its called ratio bcuz the increase at the same pace

So now look at the earth part, u got to find out how did 3 become 120, so just divide them

120/3 = 40 , so 3 x 40 = 120

So if they multiplied the right ( earth) by 40, u do the exact same on the left ( Jupitar)

8 x 40 = 320

Thats your answer my friend
