Answer:

The correct answer is -21 degrees.

Step-by-step explanation:

We know that the original temperature was -12 degrees. If the temperature drops another 9 degrees, this means that it is getting colder or the temperature is getting lower; this lets us know that we should subtract 9 from the original temperature. This is modeled below:

-12 - 9

Now, we simply have to perform the subtraction to get:

-21 degrees

Hope this helps!

Scura makes sun block and their annual revenues depend on how much they sell. Let x be the quantity of 5 oz. bottles of sun bloc

harina [27]

Answer:

a) 50,000 bottles

b) x = 45

Step-by-step explanation:

We are given the following in the question:

The annual revenue of sun block depends on how much they sell.

Let x be the quantity of 5 oz. bottles of sun block that they make and sell each year measured in 1000 's of bottles.

For x = 10,

10,000 bottles were made and sell each year.

For x = 25,

25,000 bottles of sun block were made and sell each year.

a) x = 50

$\text{Number of bottles} = 50\times 1000 = 50,000$

Thus, 50,000 bottles of sun block does Scura make and sell.

b) Scura produces and sells 45000 bottles of sunblock

We have to find the value of x

$x = \displaystyle\frac{\text{Number of bottles}}{1000} = \frac{45000}{1000} = 45$

Thus, x = 45 if Scura produces and sells 45000 bottles of sunblock.

Answer: Choice A) 9

=================================================

Explanation:

We have some variable r that we divide over 3, and then we add on 5. Note the order of operations PEMDAS says to divide first and then add (since D comes before A in PEMDAS).

When we isolate r, we follow PEMDAS in reverse and undo everything. We undo addition by subtracting 5 from both sides

$\frac{r}{3} + 5 \le 8\\\\\frac{r}{3} + 5-5 \le 8-5\\\\\frac{r}{3} \le 3\\\\$

Then we undo the division happening to r. So we multiply both sides by 3

$\frac{r}{3} \le 3\\\\3*\frac{r}{3} \le 3*3\\\\r \le 9\\\\$

Since r is less than or equal to 9, this means that r could be 9 or smaller

Only choice A applies.
