Eric takes a train to his parent’s house 320 miles away. If the trip takes 4 hours, what is the unit rate of the train? 1. Use the known information to write a rate.
2. The train’s rate: StartFraction 320 miles over 4 hours EndFraction
3. Write an equivalent rate with a denominator of 1.
4. Unit rate: ???

5. Check: The product of the unit rate and the total time should equal the total distance.

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3

step-by-step explanation:

u take $30 minus $24. the answer/original($30)

do it yourself this is easy

step-by-step explanation:

since no one answered yet i will give it a shot, not completely sure tho.

i think it should be y=cos(x+2pi), (third answer, answer c)

good luck.
