A train traveled 63.75 miles at a rate of 85 miles per hour. Which equation can be used to find h, the number of hours it took the train to travel this distance? 85 - h = 63.75 63.75 = 85h 63.75 + h = 85 85 = 63.75h

 63.75 = 85h

Solving gives 0.75 hours.

Step-by-step explanation:

we now that speed = distance / time

therefore time will be Distance / speed

Given that distance = 63.75miles

Speed= 6=85miles per hour

Time(h) = 63.75miles/ 85. equation 1

But from the options given, the equation that can also  be used to find number of hours is

63.75 = 85h

such that making h subject of formula  still give us

h= 63.75/85  as in equation 1 above

solving gives that Time ( h) = 0.75 hours .

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer
