A driver’s distance varies directly as the amount of time traveled. After 6 hours, a driver had traveled 390 miles. How far had the driver traveled after 4 hours?

260

Step-by-step explanation:

you would divide 390 by 6 to see how many hours were  per hour, which is 65. You would then multiply it by 4 to see how far they drove in 4 hours, and you get 260. To prove this is right for sure you could multiply 65x2 which is 130 and add 130+260 which would make up the 6 hours and you’d get 390

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
