1. The cost is proportional to the number of tickets because the difference is constant. (Don't have a graph sorry) but all you have to plot is (1, 12) (2, 24)
2. The book palace because the difference stayed the same.
And I'm just wondering who is your math teacher?
Answer:
30 bucks per square foot
Step-by-step explanation:
8.2x-2.1x=183
is the equation.
H= -1 here's why:
7 = 12 + 5h
First you subtract 12 from both sides then the equation would look like:
-5 = 5h
Then you would divide the equation by 5 from both sides it would then look like:
-1 = h
From the first two inference, it takes her phone 1 minute to charge 2% i.e 1 minute of charge = 2% of battery.
Therefore; charging from scratch,
1 min = 2%
x mins = 50%.
using cross multiplication,
x mins = (50% × 1 min) ÷ 2%.
x = 25 mins.
For 90%, applying the same formula,
y min = (90% × 1 min) ÷ 2%
y = 45 mins.
So from zero percent, it will take Dana's phone 25 minutes to charge to 50% and 45 minutes to charge to 90%.
