The answer to that question is 4
4/3 = 16/12
One container could be 5/16 one could be 4/16 and one could be 7/16
Hope I helped! Best of luck!
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.
You can either multiply both equation by -2 or multiply both equations by 3 because when you multiply -2 you can eliminate x term
1. -2(x) -2(y) = -2(1) -> -2x -2y=-2
So far
-2x-2y=-2
+
2x-3y= -30
(-2x+2x) + (-2y-3y)= -32
0-5y = -32
Y= 32/5
Substitute y with 32/5
X+ 32/5= 1
Minus -32/5 over
X= -27/5
I don’t know why my answer doesn’t match with those answers above. I also checked by calculator. Did you write the question wrong?
