2.  (6, 0.7) (10, 1.9)

3. $10.99D + $9.99  ≤ $100

Step-by-step explanation:

1. AX + 4AX = 51 + 2AX

 5AX = 51 + 2AX .... -2AX both side

3AX = 51   .. divide 3A

X = 17/A  --- answer is (A)

2. 10y = 3x -11

   (2, 0.5):       3*2 -11 = - 5     10y = 10*0.5 = 5    ..... not correct

    (4, 1)            3*4 - 11 = 1       10y = 10*1 = 10 ....... not correct

   (6, 0.7)        3*6 - 11 = 7       10y = 10*0.7 = 7  .....Correct

   (8,2.3)          3*8 -11 = 13       10y = 10*2.3 =23   ..... not correct

   (10, 1.9)        3*10 -11 = 19       10y = 10*1.9 = 19   .... correct

3.  1D cost $10.99

More halp wanted and needed
Semenov [28]
I believe your answer is the first option, 1/2 ft.
 
*Volume is expressed by length x width x height. 

If we multiply the length 5/7 and the height 1 & 1/2 we get 15/14:

*To multiply fractions you must multiply across, multiply the numerator (or top number) by the numerator and the denominator (bottom number) by the denominator. 

- Let's turn 1 & 1/2 into a mixed fraction to make things a little easier. 1 & 1/2 also equivalent to 3/2

-Multiply the numerators together, 5 from the 5/7 and now 3 from the 3/2 
(5 x 3 = 15)

-Multiply the denominators together, 7 from the 5/7 and 2 from the 3/2 
(7 x 2 = 14)

Therefore, 5/7 x 1 & 1/2 is 15/14.

Now what multiplied by 15/14 equals 15/28?

Well... 1 x 15 = 15. That gives us our numerator, 1.

2 x 14 = 28... and we have our denominator 2. 

Putting those two together we get a fraction of 1/2. Your width is then 1/2 ft.


I'm so sorry for all the work here! I know it's a lot. I hope it's not too confusing to look at. Hopefully this helps!
