When attempting to do his homework, mark incorrectly uses the addition property of equality below. which statement would correct mark’s error?
1) 8 + x = 2
2) 8 – 8 + x = 2
3) x = 2
a.
to balance the equation, mark should also subtract 2 from the right side of the equation in step 2.
b.
to balance the equation, mark should also subtract 2 from both sides of the equation in step 2.
c.
to balance the equation, mark should also subtract 8 from the right side of the equation in step 2.
d.
to balance the equation, mark should also add 8 to both sides of the equation in step 2.

1)

2)

3) x=2

For this case if we see the second step Mark subtract 8 from the left part of the equation but not subtract 8 from the right side of the equation, and that's an error.

So then the correct answer for this case would be:

C.  To balance the equation, Mark should also subtract 8 from the right side of the equation in step 2.

2)

3)

Step-by-step explanation:

For this case we have the following equation:

And Mark's use the following procedure to solve it:

1)

2)

3) x=2

For this case if we see the second step Mark subtract 8 from the left part of the equation but not subtract 8 from the right side of the equation, and that's an error.

So then the correct answer for this case would be:

C.  To balance the equation, Mark should also subtract 8 from the right side of the equation in step 2.

1gm = 1000mg so 0.1gm = 1000mg

first, convert the weight to kg

160lb * 1kg/2.2lb = 72.7kg

next, the dose

72.7kg * 100mg/kg = 7270mg

x = 17

step-by-step explanation:

1st step: isolate x.

24 - 3x = -27

-24         -24

-3x   =   -51

2nd step: divide.

-3x     =   -51

  3             3

  x       =     17

hope this
