The set s consists of all odd multiples of 3: s = { -9, -3, 3, }. if the integers x and y are in s, then which of the following must also be in s?

a) xy
b) x + y
c) x - y
d) x/y
e) -x - y

explain too, .

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.  

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10
