Answer:

AN = 9

Step-by-step explanation:

so we can imagine this in a line like:

A---------------N---------------X

Step 1 : solve for x

AX=21 (our total)

because we know that AN+NX together makes AX, we put that into an equation

<u>AN + NX = AX </u>

(2x+1) + (3x) = 21

2x + 1 + 3x = 21  <-- <em>subtract 1 from both sides</em>

2x + 3x = 20  <-- <em>add 2x +3x </em>

5x = 20   <-- <em>divide 5 from both sides</em>

<u>x = 4</u>

Step 2 : input x into AN

AN = 2x + 1  <-- <em>input 4 for x</em>

AN = 2(4) + 1  <-- <em>simplify from there</em>

<u><em>AN = 9</em></u>

<u><em /></u>

Answer:

1.  5/6 ≥ 2/3

2. 1/5 ≤ 2/8

3. 9/10 ≥ 6/8

4. I can't see it's out of the pic

5. 7/8 ≥ 5/10

6. 2/5 ≥ 2/6

7. 1/3 ≤ 3/8

8. I can't see it's out of the pic.

9. 8/10 ≥ 3/4

10. 3/8 ≤ 11/12

11. 2/3 ≤ 10/12

12. Can't see :(

13. 3/8 ≤ 7/8

14. 2/4 = 4/8

15. 6/8 ≥ 8/12

16. Can't see

Step-by-step explanation: All you have to do is divide the numerator by the denominator to make it into a decimal. For instance....

5/6 = approximately 0.83

I hope this helps you! It took forever....

and then there is 21.95 per gallon

the better deal would be the 5 gallon bucket for 97.45 because if u buy it this way, it is cheaper by the gallon
