X/-2=-7 evaluate and show work

x = 14

Step-by-step explanation:

Okay so the equation looks like this:

X/-2 = -7

In order for us to get rid of the -2 we are going to have to multiply -2 on both sides of the equal sign, so that we only have x on one side of the equal sign and numbers on the other:

X/-2 = -7

 *-2  *-2

since multiplying or dividing a negative number by a negative number gives you a positive -7 is going to become 14 and x remains on the other side of the equal sign:

x = 14

Now to check our work we are going to place 14 where the x variable is in the equation:

X/-2 = -7 or (14)/-2 = -7

-7 = -7

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
