Question
Cable company A charges $45 a month for cable plus a $18 installation fee. Cable B charges $39 a month for cable plus a $30 fee for installation. Which inequality can be used to find out when the monthly cost for Cable company A is less than Cable company B?
a)39x+30<45x+18
b) 45x+18>39x+30
c) 45x+18<39x+30
d)39x+18<45x+30
Answer:
c) 45x+18<39x+30
Step-by-step explanation:
Step 1
We have to find the Algebraic expressions for the cable companies
Cable company A charges $45 a month for cable plus a $18 installation fee.
Let the number of months be represented as x
Hence, this is represented as:
$45 × x + $18
= 45x + 18
Cable B charges $39 a month for cable plus a $30 fee for installation.
Let the number of months be represented as x
Hence, this is represented as:
$39 × x + $30
= 39x + 30
The inequality that can be used to find out when the monthly cost for Cable company A is less than Cable company B?
= Cable company A < Cable company B
= 45x + 18 < 39x + 30
Therefore option c is correct
Answer: True.

Step-by-step explanation:
Just convert all your measurements. 1gallon is 4 quarts. So 9 gallons= 36qt and 6 gallons= 24qt so the question becomes 36qt+1qt+24qt+1qt=62qt or 15.5 gallons.
Option D:
The length of LJ = 3.5
Solution:
In the triangle LJK,
LK = 9, ∠K = 23°, ∠J = 89°
To find the length of LJ:
<u>Law of sine: </u>
A, B, C are the angles of the triangle and
a, b, c are the sides of the triangle.
Here for ΔLJK,
The side opposite to angle L is <em>l</em>.
The side opposite to angle J is <em>j</em>.
The side opposite to angle K is <em>k</em>.
Take only two sides.
LJ = 3.5 (approximately)
Option D is the correct answer.
The length of LJ = 3.5.
