$40/12 = unit rate simplify = 10/3
$10/3 per book
18 * 10/3 = $60 for 18 copies
45c/100=9.25=37/4
c=20 5/9 (185/9)
Answer:
d=13.
Step-by-step explanation:
d=
From question statement,
,
,
put above values in the distance formula,we obtain
d=
d=
d=
d=
d=13
Simplify. Combine like terms
7y - 3y = 4y
-12 + 9 = -3
----------------------------------------------------------------------------------------------------------------
4y - 3 = 0
Isolate the y. Note the equal sign. What you do to one side, you do to the other side. Do the opposite of PEMDAS.
4y - 3 (+3) = 0 (+3)
4y = 3
4y/4 = 3/4
y = 3/4
-----------------------------------------------------------------------------------------------------------------
y = 3/4 is your answer
