3x - 12 = -15

Add 12 on both sides.

-12 + 12 = 0

-15 + 12 = -3

The equation is now 3x = -3.

Divide both sides by 3 to isolate the variable.

3x / 3 = x
-3 / 3 = -1

So, x = -1.

Can someone help me on this question.
Temka [501]
46! Because 5 times 3 is 15 and the two big rectangles are equal, that’s 15+15. (30) 5x1 is 5 and THERES two equal things like that so 5+5 (10). 3x1 is 3 and THERES also two equal things so add 3+3. (6) add 30+10+6 which makes 46! :)

1. A sum of money is shared among Jessica, Amanda, and Beverly in the ration 8:9:3
astra-53 [7]

Answer:

$200

Step-by-step explanation:

Amanda       Beverly

     9         :       3

difference between Amanda and Beverly = 9 - 3 = 6 portions.

∴ value of 6 portions = $60

   value of 1 portion  =  $ 60 / 6

                                  = $10

Total no. of portions = 8 + 9 + 3 = 20

Total sum of money to be shared = value of 1 portion x Total no. of portions

                                                         = $10 x 20

                                                         = <u>$200</u>
