Thought I already answered this.  I must have forgotten to click "add your answer."

We have similar triangle trianges ABC ~ ADE so

BC:AB = DE:AD

BC:2  = 10 : (2+3) = 10:5 = 2:1

So BC=4 because 4:2 = 2:1

Choice C.

(WILL GET BRAINLESS IF YOU EXPLAIN)
Vaselesa [24]

Answer:

Quran Surah Fatir 35:5

Step-by-step explanation:

What this verse is trying to say is, don't let this life you are living right now mislead you and misguide you!  For example, you see non-believer doing zina, drinking alchoal, or doing bad sins. These are some of the major distractions and the disbelievers who do these types of stuff will try to mislead you by making you do this also with them.

(I want to clarify it's better if you go to an Imam or somebody knowledgeable and ask them because they will help you explain this verse in a more understandable way. I tried but it's better to check an Imam!)

Hope this helped!

What is the value of x in the following equation? -3x-2=2x+8
Arlecino [84]

Answer:

-2 =x

Step-by-step explanation:

-3x-2=2x+8

Add 3x to each side

-3x+3x-2=2x+3x+8

-2 = 5x+8

Subtract 8 from each side

-2-8 = 5x+8-8

-10 = 5x

Divide by 5

-10/5 = 5x/5

-2 =x

Number 13 is what I need done
Nadusha1986 [10]
Instead of using an = sign we use \leq becuase its less than or equal to 100 dollars.

The equation of the line is y=10x+7

sub in 100 for y and the inequallity sign

10x+7\leq100

solve so x is isolated

10x\leq93
x\leq9.3

technically the answer is 9 because you cant buy a fraction of a CD
