Simplify 5 - 2x -3 +x

a) 2-x b) 1 C) x-2 d) 2-2x

Answers

5 - 2x - 3 + x = (5 - 3) + (-2x + x) = 2 - x

Answer: a) 2 - x

Lets break this into parts:

5 - 3 = 2
-2x + x = -x

So thats 2-x.

Which of the following equations matches the graph?

Answers

Answer:

The answer closest to the graph is C. y= 5x-4

Step-by-step explanation:

If you graph the first answer (A. y= 1/5x+4), there is going to be a horizontal line above the x intercept. If you graph the second answer (B. y= 1/5x-4), there is going to be a horizontal line below the x intercept.

In a group of 75 fourth graders, 20% do not like hot chocolate. How many students like hot chocolate

Answers

$20\%\ do\ not\ like\ hot\ chocolate,\ therefore\n100\%-20\%=80\%\ like\ hot\ chocolate\n\np\%=(p)/(100)\to80\%=(80)/(100)=(8)/(10)=(4)/(5)\n\n80\%\ of\ 75=(4)/(5)\cdot75=4\cdot15=\boxed{60}\leftarrow answer$

Let find how many do not like hot chocolate.

.20*75 = 15 fourth graders don't like hot chocolate.

Now lets see how many like hot chocolate

75 -15 = 60 kids like hot chocolate.

Another way to do this is you know that 20% of kids don't like hot chocolate then that means 80% must like hot chocolate.

So now you just have to do .8*75 and you get 60
