(for this answer i'm gonna use 0 to make it easier 
firstly you have to reoder the terms like this : 18 + 3 (-13+9f)=0
then  you multiply -13 and 9f by 3 like this : 18 + (-13 x 3 + 9f x 3)=0 and it should be like this: 18 + (-39 + 27f)=0
Next you have to combine like terms which is: 18 + -39 and you will get -21 and you add it to 27f which is: -21 + 27f=0 and you have to solve for the variable f and move all the terms containing f to the left and all other terms to the right.

Tom and chuck share a reward of $234 in a ratio of 3:6. What fraction of the the total reward does Tom get?
Elza [17]

Answer:

1/3

Step-by-step explanation:

so the ratio is 3:6

there are 9 total parts

divide 234 by 9 and you get 26

there are $26 per part

multiply 26 by 3 to get Tom's reward, which is 78

multiply 26 by 6 to get Chuck's reward, which is 156

the fraction of the total reward that Tom gets is 78/234<em> (this is Tom's $ over total)</em>

simplify and get 1/3

What is the solution to the inequality 3x - 12| ≥ 6?
natta225 [31]
<h3>Answer:  x ≤ 2 or x ≥ 6</h3>

========================================

Work Shown:

|3x-12| ≥ 6

3x-12 ≥ 6 or 3x-12 ≤ -6  ..... see note below

3x ≥ 6+12 or 3x ≤ -6+12

3x ≥ 18 or 3x ≤ -6+12

3x ≥ 18 or 3x ≤ 6

x ≥ 18/3 or x ≤ 6/3

x ≥ 6 or x ≤ 2

x ≤ 2 or x ≥ 6

----

Note: if |A| ≥ B, then A ≥ B or A ≤ -B where B is some positive number.

Example: |x| ≥ 5 means either x ≥ 5 or x ≤ - 5
