Inequality tells us about the relative size of two values.
Mathematics is not always about "equals", sometimes we only know that something is greater or less than.
Example: Alex and Billy have a race, and Billy wins!
What do we know?
We don't know how fast they ran, but we do know that Billy was faster than Alex:
Billy was faster than Alex
We can write that down like this:
b > a
(Where "b" means how fast Billy was, ">" means "greater than", and "a" means how fast Alex was)
Inequalities: Symbols and Vocabulary
Algebra rules / General Rules:
Isolate a positive x on the left side using algebra
Reverse the inequality sign when mult/divide by a negative
Less than: The symbol that: Looks like an L () for ess than
< ○ ) Points to the Left
● ] Caps the arrow pointing towards smaller numbers
on the number line
Points towards the smaller of two numbers (4 < 7)
> Greater than: The symbol that: Looks like the top of an R ( >
)for GReater than
> ○ ( Points to the Right
● [ Caps the arrow pointing towards larger numbers on
the number line
Open end is by the larger number (7 > 4)
Compound inequalities: usually in the form -4 < x < 4
but can also be x > -4 and x < 4

The length of a rectangular deck is 5 times it’s width. If the decks perimeter is 36feet, what is the deck area?
Answers
Answer:
45
Step-by-step explanation:
P = 2(L+W)
36 = 2(5W + W)
36 = 10W + 2W
36 = 12W
W = 3
5W = 5(3) = 15
15 x 3 = 45
The area of a rectangular deck is 45 square feet.
Given that, the length of a rectangular deck is 5 times it’s width.
What is the perimeter of a rectangle?The perimeter of a rectangle is the total distance of its outer boundary. It is twice the sum of its length and width and it is calculated with the help of the formula: Perimeter = 2(length + width).
The decks perimeter is 36 feet
Let the width of a deck is w, then the length of a deck is 5w.
Now, 2(5w+w)=36
⇒ 6w=18
⇒ w=3 feet
So, length=5w=15 feet
Area =15×3
= 45 square feet
Therefore, the area of a rectangular deck is 45 square feet.

Solve for x in the figure below
5x+18
7x-14
Answers
Answer:
16 =x
Step-by-step explanation:
The angles are corresponding angles and since the lines are parallel, they are equal
5x+18 =7x-14
Subtract 5x from each side
5x+18 -5x=7x-5x-14
18 = 2x-14
Add 14 to each side
18+14 = 2x-14+14
32 = 2x
Divide by 2
32/2 = 2x/2
16 =x
Answer: x=16
Step-by-step explanation:
make it an equation: the equation 5x+18=7x-14
then, solve for x.
steps :
1. add 14 to both sides to get 5x+32=7x
2. subtract 5x to both sides to get 32=2x
3. divide both sides by 2 to get 16=x

Answers
Answer:
t =7
Step-by-step explanation:
48t-18=57t-81 Subtract 48t from both sides
48t-48t - 18 =57t-48t - 81 Combine
-18 = 9t - 81 Add 81 to both sides
-18+81 = 9t -81 + 81 Combine
63 = 9t Divide by 9
63/9 = 9t/9

A couple realizes a real estate financing of R $ 180,000.00, to be paid in 360 monthly installments, with an effective interest rate of 1% per month. The first installment is paid one month after the funds are released and the monthly installment is R $ 500.00 plus 1% interest on the outstanding balance (amount due before payment). Note that, with each payment, the outstanding balance is reduced by R $ 500.00 and consider that there is no arrears. By making the payment in this way, the amount, in reais, to be paid to the bank in the tenth installment is
a) 2,075.00.
b) 2,093.00.
c) 2,138.00.
d) 2 255.00.
e) 2 300.00.
Answers
Answer:
ANSWER: letter D
Step-by-step explanation:
In the tenth installment, the debit balance is, in reais, of
180000 - 9. 500 = 175500
The 1% interest on this amount results in:
1% . 175 500 = 1755
Thus, the tenth installment is, in reais, 500 + 1755 = 2255
