1) 4x=24 2)3x=18 3)9x=81

1) 6 2) 6 3) 9

Step-by-step explanation:

4x=24 can be solved by dividing both sides by 4, which would isolate x. 4x divided by 4 is x, and 24 divided by 4 is 6. you are left with x = 6. the answer for 1) is 6.

3x = 18 can be solved similarly by dividing both sides by 3. you are left with x = 6.

9x = 81 is also solved similarly by dividing both sides by 9. 81 divided by 9 is 9, so x = 9.

step-by-step explanation:

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
