If the <em>n</em>-th term of the sequence is given by <em>n</em> ² - 2, then the 5th term is obtained by simply replacing <em>n</em> with 5 :
5² - 2 = 25 - 2 = 23
Write and solve an equation:
Total earnings = $782.75 = s(40 hrs) + 1.5*s*(7 hrs)
Then 782.75 = 40s + 10.5s = 50.5s
Dividing both sides by 50.5: s = 15.5. The attendant's regular hourly wage was $15.50.
Answer:
C and X , B and L , A and W , D and G are congruent
An algebraic expression is, obviously, an expression with a variable.
"A number" would represent a variable, which, in this case, we'll use y.
So, 15 decreased by twice x.
15 - y x 2 =
I hope this helped :)
