Answer:
600 miles.
Step-by-step explanation:
So basically we can write both plans as linear functions:
F(x) = $59.96+$0.14 . x
S(x) = $71.96+$0.12 . x
Where F(x) is the first plan, S(x) is the second one and X are the miles driven.
To know how many miles does Mai need to drive for the two plans to cost the same, we equalize both equations and isolate x.
F(x) = S (x)

Mai has to drive 600 miles for the two plans to cost the same-
The degree of the polynomial is 7
Neutral atoms must have equal numbers of protons and electrons
Solution: 18 electrons
Answer:
A. 
B. 
C. 
Step-by-step explanation:
A.
. Any number could work as long as the coefficients for x and y stays the same. You are basically imposing that the quantity 2x-4y (if you bring 4y to the LHS) is equal to both -3 AND
, or any number you like. But yesterday was 3/14 so let's pick a fun number!
B.
Or
. Or as long as you don't pick the same ratios of x and y you're golden. But x=1 is the easiest that comes to mind
C.
. To get infinitely many solutions you just have to rewrite the equation again. Maybe move things around if you prefer, or multiply everything by a number you lile.
Answer:
Kiesha paid $12.
Step-by-step explanation:
40% of 20 is 8. So you subtract 8 from 20 and that gives you the amount she paid.
