When subracting the negative 24 from the left and right side, the left will cancel and the right will equal -28 instead of positive.

The final answer would just be positive 7 instead of negative.

What is, 7 3/10+6 1/3+2 7/10?

snow_lady [41]

7 3/10 + 6 1/3 + 2 7/10

First change them to improper fractions

73/10 + 19/3 + 27/10

now find the common denominator which would be 30

73/10 = 219 /30

19/3 = 190/30

27/10 = 81 /30

now add (219 + 190 + 81) = 490/30

now divide 490 ÷ 30 = 16 1/3

Your answer is 16 1/3

Hope this helps. :)

What is the value of a?

dexar [7]

Answer:

a= 2x <u><em>(edit: i just forgot it should be a integer x.x, forgive my blondiness)</em></u>

Step-by-step explanation:

usually when doing equations like that, you can separate one of the parenthesis with 0

(in this case, we will use (2x-a) )

Then create a equation, which should look like:

2x-a=0

Then solve for a

$(-2x)2x-a=0(-2x)\\(-1)-a=-2x (-1) \\a=2x$
