Mathematics
1 answer:

7 0

Answer:

The ones that give a rational number answer are:

C+D

A*B

C*D

A*A

Step-by-step explanation:

A+B does not give a rational number answer; √3+2√3 = 3√3

C+D is a rational number; √25=5 and √16=4; 5+4=9.

A+D is not a rational number; √3+√16 = √3+4

A*B is a rational number; √3*2√3 = 2√9 = 2*3 = 6

B*D is not a rational number; 2√3*√16 = 2√3*4 = 8√3

C*D is a rational number; √25*√16 = 5*4 = 20

A*A is a rational number; √3*√3 = √9 = 3

On a recent day a Euro was equal to about 1.2 American dollars. Write an expression which estimates the number of dollars in x E
JulsSmile [24]

Answer:

d = 1.2e

30 dollars

Step-by-step explanation:

To write an expression, define the variables. E will be the number of euros and d will be dollars.

"Euro was equal to about 1.2 American dollars" is one euro equals 1.2 and two euros equals 2.4. So the expression is d = 1.2e.

This means if I have 1 euro, I have 1.2*1 = 1.2 dollars. If I have 2 euros, I have 1.2*2 = 2.4 dollars.

If I have 25 euros then d = 1.2*25 = 30 dollars.

What steps do I take to solve y+2&gt;1/2-2 and the solution
kakasveta [241]
<span>y+2>1/2-2 looks a little strange.  Is it OK to combine the last 2 terms?

</span><span>y+2> -3/2

Then y > -2 - 3/2, or y > -7/2.  y must be greater than -7/2, greater than -3.5.</span>
