(w - — ) - — = 0
4 7
Step 3 :
Rewriting the whole as an Equivalent Fraction :
3.1 Subtracting a fraction from a whole
Rewrite the whole as a fraction using 4 as the denominator :
w w • 4
w = — = —————
1 4
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding fractions that have a common denominator :
Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
w • 4 - (5) (4w - 5
)
——————————— = ——————
4 4
Equation at the end of step 3 :
(4w - 5) 6
———————— - — = 0

Yes, in order to be a real number, it must not contain the number i, which is an imaginary number, represented by √-1. Since 9/10 is equal to .9, there is no i in the number, meaning it is a real number.
Jim is ranked third best in his class of 50 students.
The answers are A., C., and E.
The chart shows that Camila has a greater rate of change than Lydia, so B is incorrect. C and E are true because the graph shows that Camila's rate of change is $7/hour, making C true, which means that in 2 hours, she gets paid $14, making E true.
Answers: A., C., and E.
