18. A jar contains 200 coins.

Mathematics
1 answer:
dimaraw [331]2 years ago
6 0

Answer:

Step-by-step explanation:

3 coins pulled are 10 cents or more

5 coins are under 10 cents    

so 3 out of 8 coins are 10 cents or more    

the jar contains 200 coins

This is a ratio problem  3 is to 8  as  x (an unknown value) is to 200

3/8  = x/200       solve for x

times both sides by 200

200(3/8) = x                          solve directly here using a calculator

600/8  = x                             or keep similifying until you can divide more

300/4  = x                              easily   I kept dividing the numerator and the

150/2   = x                              denominator by 2 until i got 150/2 = 75

75 = x

Answer:

The first option: -5/4x + 1/6.

Step-by-step explanation:

(3/4x - 2/3) - (-5/6 + 2x)

= (3/4x - 2/3) + 5/6 - 2x

= 3/4x - 2x - 2/3 + 5/6

= 3/4x - 8/4x - 4/6 + 5/6

= -5/4x + 1/6

So, the first option: -5/4x + 1/6.

Hope this helps!

(4) |-5 + (-2)| _____ |5 + 2| <br> &lt;<br> &gt;<br> =
nikitadnepr [17]

Hi

The answer would be =

Why?

The `| |` symbols mean actual value, which makes every number inside of it positive. That would mean, following the rules of actual value, the equation would look like:

5 + 2 _____ 5 + 2

Both add up to 10, so both equations are equal.
