Answer:
addition add 3 to both sides to isolate the variable term
<h3>
Answer:</h3>
<em>Your answer would be y=x+3/12</em>
<h3>
Step-by-step explanation:</h3>
Firstly, you'll switch sides of the equation.
<em>y=12x+3 ---> x=12y-3</em>
Next, add 3 to both sides.
<em>x=12y-3 ---> 12y-3+3=x+3</em>
Simplify it.
<em>12y-3+3=x+3 ---> 12y=x+3</em>
Then, divide both sides by 12.
<em>12y=x+3 ---> 12y/12 = x/12 + 3/12</em>
Simplify once more.
12y/12 = x/12 + 3/12 --- y= x+3/12
<u>y=x+3/12 would be your answer.</u>
Answer:
B
Step-by-step explanation:
essentially the plan that increases the price the most per week reaches the goal of $12 fastest.
plan A is $0.10 per week.
plan B it is not clear, if it means 10% of the original price every week, or every week 10% of the price of the previous week. I assume the first and simplest.
that means 10% of $8 = $0.80 per week.
plan C : the same amount every week until reaching $12. we need to increase in total by $4 (from $8 to $12). to reach these $4 in 8 weeks, we need to increase the price every week by 4/8 = $0.50.
plan D : $0.25 per week.
so, the plan with the highest increase every week and therefore the fastest one reaching $12 is plan B.
