Answer:

I'm pretty sure that the answers would go, Wrong, increased, 9 1/2 points, 6 5/8 points, dropped, 12 3/4 points.

Step-by-step explanation:

The reason why it would be wrong is because the amount of points lost was less than the total amount of points gained.

In week one and two the company gained 9 1/2 points and 6 5/8 points. When you add them together, you get 16 1/8 points.

In week three the company lost 12 3/4 points. If you multiply the fraction to change the denominator to 8, the mixed fraction becomes 12 6/8.

16 1/8 - 12 6/8 = 3 3/8

As you can see, there are still points left over.

In the fourth week, they ended up losing all of their points and then some more, but from my understanding it's just asking about the third week.

Hope that this helps!

Susie has a bag with 8 hair pins, 7 pencils, 2 snacks, and 4 books. What is the ratio of books to pencils?

Viefleur [7K]

<h3>Hello there!</h3>

The first thing we need to do here is see which information is relevant.

The question is asking for the ratio of books to pencils.

Therefore, we only need the number of books and pencils - all other information given is irrelevant in this scenario.

Number of books - 4

Number of pencils - 7

Now, we can order this as a ratio.

A ratio is two numbers put as a proportion. It's normally written out as first number : second number.

In this case, it's the ratio of number of books : number of pencils.

Fill in the number of books and number of pencils into each side of the equation.

number of books : number of pencils

4 books : 7 pencils (the unit is normally dropped)

So therefore, 4:7 would be your final answer.

Hope this helped!

What is -1/3+w=5 3/8 express in simplest form

Elodia [21]

Let's solve your equation step-by-step.
 $\frac{-1}{3}$ +w=5 $\frac{3}{8}$ 
Step 1: Simplify both sides of the equation.
w+ $\frac{-1}{3}$ = $\frac{43}{8}$ 
Step 2: Add $\frac{1}{3}$ to both sides.
w+ $\frac{-1}{3}$ + $\frac{1}{3}$ = $\frac{43}{8}$ + $\frac{1}{3}$ 
w= $\frac{137}{24}$ 

Answer:w=5 $\frac{17}{24}$
