This equal 1.88 kilometers

What is the value of the expression? (14 – 6) • (2 + 4) A. 14
B. 48
C. 6
D. 4

Answers

To solve expressions like the one above, you must first complete the operations inside the parenthesis. We know this because of PEMDAS, wherein the P (representing parenthesis) comes first.

(14 - 6) * (2+4) = (8) * (6)

Next, we must simplify the expression. There is only one operation left to complete, multiplication, so that is what we are going to do next.

8 * 6 = 48

Therefore, your answer is B. 48

I hope this helps! :)
(14-6) x (2+4)
= 14 x 2 + 14 x 4 - 6 x 2 - 6 x 4
= 28 + 56 - 12 - 24
= 48

Therefore the answer would be : B. 48.

Hope this helps !

Answer:

yea

Step-by-step explanation:

I need help on a another one please this is the problem -2(c+4) -3x x=2

Answers

so -2(c+4)-3x

when x=2
-2(c+4)-3(2)
pemdas
-2c-8-3(2)
-2c-8-6
-2c-14
or
-2(c+7)
-2(c+4)-3x 
substitute x=2
-2(c+4)-3(2)
then distribute
-2c-8-3(2)
simplify
-2c-8-6
=-2c-14
-2(c+7)

Action movies make up 85% of Devon's movie collection. If he has 20 movies,how many action movies are in Devon's collection?

Answers

Method 1

We can find the number of Devon's movie collection by multiplying its percentage by the number of Action movies. That is;

Number of Devon's movie collection = (85)/(100) * 20=(85)/(5) =17

Method 2

We can also use ratio and proportion. According to the question, out of every 100 Action movies 85 are Devon's Movie collection. This means,


Action movies                                        Devon's collection                  

100                                                                         85

20                                                                             x

If 100 corresponds to 85, then 20 will correspond to a less value than 85. If less more divides,Hence,

x=(85 * 20)/(100)=17.

Therefore he has 17 movies that are in Devon's collection.
The answer is 17, because you know it’s going to be most of it, so you do 20 times .85 on your calculator, and you have your answer! :)
