Shau-uen solve the equation 18.5w+6.5w-2.8w=149.1 her work is shown below

step(1)
18.5w+6.5w-2.8w= 149.1^0
step(2)
25w-2.8w= 149.1
step(3)
-2.8w=5.964
step(4)
w= -2.13
in which step did shaun make her first error?

a. step 1
b. step 2
c. step 3
d. step 4

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

a

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|
