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.

step-by-step explanation:

1. practice, practice & more practice

2. review errors

3. master the key concepts

do not try to memorise the processes.

4. understand your doubts.

5. create a distraction free study environment

6. create a mathematical dictionary

7. apply maths to real world problems.

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

2

x=5

step-by-step explanation:

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )
