Ataxi cab costs $1.50 for the first mile and $0.75 for each additional mile which equation could be solved to find how many miles you can travel in a taxi for $10 given that x is the number of additional miles
a| 1.5x + 0.75 = $10
b| 0.75x + 1.5 = $10
c| 1.5x - 0.75 = $10
d| 0.75x - 1.5 = $10

which is the solution of t/2.5 = -5.2

a| t= -13
b| t= -2.08
c| t=2.08
d| t=13

which expression is equivalent to 5x - 30

a| 5(x - 30)
b| 5(x-6)
c| 5x(x-6
d| x(5-30)

in a science experiment the tempature of a substance is changed from 42.f to -54.f at an average rate of -12 degrees per hour over how many hours does the change take place

a| -8 hours
b| 1/8 hours
c| 1 hours
d| 8 hours
