It 3x - 2 = 7, then 3x = 9<br> is an example of the ?
vova2212 [387]

Answer:

Addition Property of Equality

Step-by-step explanation:

So we had:

3x-2=7

And then we got:

3x=9

We did this by adding 2 to both sides of the equation. When we added 2, the left side cancelled and the right side equated to 9:

(3x-2)+2=(7)+2\\3x=9

Since we added 2 to both sides, this is an example of the addition property of equality.

Answer:

a 166 67/100

b 20 1/4

c 829 77/100

d 664 47/50

e 208 4/25

Step-by-step explanation:

you need to find the common denominator (the number on the bottom) so for the first one when can 10 = 100 if you multiply 10 x 10 you get 100 so multiply the entire fraction by 10 and you will get 10/100 so the equation would be 381 10/100 - 214 43/100 which equals 166 67/100 then just do the same thing for the rest of them
