Answer:
50mph
Step-by-step explanation:
Say for example car A increases by 10 miles per hour and car B decreases by 10 miles per hour. If car A2 = car B3 then by eliminating a few numbers and finally get to 50 you get the following equation.
A = 50+10
b = 50-10
A = 60
B = 40
A2 = 120
B3 = 120
120 = 120
Answer:
c=-6
Step-by-step explanation:
I used a calculator and paper and a pencil d---------b yeah :D yr welcome
Ok, so you would want to simplify both sides of the equation
(-1/3)(-12) + (1/3)(-12c)=-20 (here you distribute)
4+4c=-20
Then, subtract 4 from both sides
4c+4-4=-20-4
4c=-24
Then divide both sides by 4
4c/4=-24/4
c=-6
Brand A has a unit price of .37 cents
brand B has a unit price of .38 cents
so you get 2 more pencils for .1 cent each, so brand B is the better deal
