a) Write an equation in terms of x that represents the problem. (b) Solve the problem.
Seven less than the quotient of a number and 2 is equal to − 12. Find the number.
Part 1 of 2
The equation that represents the problem is _____?
The number is______?
Answer:
Part 1: (n÷2)-7 = -12
Part 2: n = -10
Step-by-step explanation:
Part 1:
Let's first write "the quotient of a number and 2" using numbers and variables. Let "n" represent "a number". The key word that we see here is quotient, meaning we have to divide something by something else. "The quotient of a number and 2 means that "a number" is the dividend (number that is divided) and "2" is the divisor (number that divides the dividend). Therefore we obtain:
n÷2
The first part says "seven less than the quotient of a number and 2". The keyword here is less, meaning we have to use subtraction. Therefore:
(n÷2)-7
The last part says "is equal to -12". Therefore the whole expression we just wrote is equivalent to -12:
(n÷2)-7 = -12
Part 2
Remember the Order of Operations:
Parentheses
Exponents
M/D: Multiplication/Division (whichever comes first in the equation)
A/S: Addition/Subtraction (whichever comes first in the equation)
Start by adding 7 to both sides
(n÷2) = -5
Then, multiply both sides by 2
[tex]\frac{n}{2}=-5\\n=-10[/tex]
Note: I used a fraction to display the division because it is easier to see why we have to multiply both sides by 2; to cancel out the denominator.

What percent of values is between the first and third quartiles?
The data set is 50, 75, 100, 125, 150, 175, 200, 225, 250
Answer:
[tex]55.555...\ (\%)[/tex]
Step-by-step explanation:
What percent of values is between the first and third quartiles
[tex]\text{Quartile 1} =\frac{75+100}{2} =87.5[/tex]
[tex]\text{Quartile 2} =\frac{200+225}{2} =212.5[/tex]
50 < 75 < 87.5 < 100 < 125 < 150 < 175 < 200 < 212.5 < 225 < 250
Then we have 5 values between the first and third quartiles which are :
100, 125, 150, 175, 200

Factor the polynomial and use the zeros to identify its graph. x4 − 5x3 − 20x2 + 60x + 144
The zeros of the polynomial are -3, -2, 4 and 6 and the graph of the polynomial is graph (a)
How to factor the polynomial?The polynomial is given as:
P(x) = x^4 - 5x^3 - 20x^2 + 60x + 144
Expand the polynomial function
P(x) = x^4 - 10x^3 + 5x^3 + 24x^2 - 50x^2 + 6x^2 + 120x - 60x + 144
Rewrite the function as:
P(x) = x^4 - 10x^3 + 24x^2 + 5x^3 - 50x^2 + 120x + 6x^2 - 60x + 144
Factorize the function
P(x) = x^2(x^2 - 10x + 24) + 5x(x^2 - 10x + 24) + 6(x^2 - 10x + 24)
Factor out x^2 - 10x + 24
P(x) = (x^2 + 5x + 6)(x^2 - 10x + 24)
Expand each bracket
P(x) = (x^2 + 3x + 2x + 6)(x^2 - 4x - 6x + 24)
Factorize each bracket
P(x) = [x(x + 3) + 2(x + 3)][x(x - 6) - 4(x - 6)]
Factor out x + 3 and x - 6
P(x) = (x + 3)(x + 2)(x - 4)(x - 6)
Set to 0
(x + 3)(x + 2)(x - 4)(x - 6) = 0
Solve for x
x =-3, -2, 4 and 6
Hence, the zeros of the polynomial are -3, -2, 4 and 6 and the graph of the polynomial is graph (a)

Thabo bought bread for R9,50, sweets RO,50, biscuits for R2,75 and coldrink for R11,35. a) How much did Thabo spend at the shop? b) If Thabo had R50, how much was his change?
Answer:
A) R24.10
B) R25.90
((ASSUMING THERES NO TAXES WITH THE PAYMENT))
Step-by-step explanation:
A)
first add up the costs of each item to get the ttal cost with addition as follows...
9.50 + 0.50 + 2.75 + 11.35 ((Adding like terms by adding 0.50 to 9.50 equaling 10.00))
10.00 + 2.75 + 11.35 ((adding the more simple options togeter since .75 is a more common fraction at 3/4))
12.75 + 11.35 ((finnishing off the system by adding the last two numbers together equaling to 24.10))
therefore Thabo spent a total of 24.10
B)
to find out the change, all we need to do is subtract the total cost from the total amount Thabo used to pay as shown below
50.00 - 24.10
in conclusion, Thabo would have R25.90 in change from the transaction ((assuming theres no tax))
4) Cody invests $2,733 in a retirement
account with a fixed annual interest rate of
9% compounded 12 times per year.
How
long will it take for the account balance to
reach $9,589.78?
Answer:
t = 14 years
Step-by-step explanation:
r = R/100
r = 9/100
r = 0.09 per year,
Then, solve the equation for t
t = ln(A/P) / n[ln(1 + r/n)]
t = ln(9,589.78/2,733.00) / ( 12 × [ln(1 + 0.09/12)] )
t = ln(9,589.78/2,733.00) / ( 12 × [ln(1 + 0.0075)] )
t = 14 years
Summary:
The time required to get a total amount of $9,589.78 with compoundeded interest on a principal of $2,733.00 at an interest rate of 9% per year and compounded 12 times per year is 14 years.

On a spinner, there are twenty equal-size sections numbered from 1 to 20. Which spinner game is fair? Show your work.
The spinner game is an illustration of probability, and the spinner game that is fair is (b) If you spin a number greater than 10, you win.
How to determine the fair game?The number of sections in the spinner is given as:
n = 20
There are 10 numbers greater than 10 i.e. 11 to 2.
So, the probability that a number greater than 10 is spun is:
P = 10/20
P = 0.5
The probability that a number that is not greater than 10 is spun is calculated using the following complement rule
q = 1 - p
This gives
q = 1 - 0.5
Evaluate
q = 0.5
Notice that both probabilities are the equal
Hence, the spinner game that is fair is (b) If you spin a number greater than 10, you win.

Answer:
2,012 is greater than 30
Step-by-step explanation:
The correct solution for the inequality is k > -9.
Given is an inequality -2k + 12 < 30, we need to solve for k,
To solve the inequality -2k + 12 < 30 for k, follow these steps:
Subtract 12 from both sides of the inequality to isolate the term with 'k':
-2k + 12 - 12 < 30 - 12
-2k < 18
Divide both sides by -2, but remember that when you divide an inequality by a negative number, the direction of the inequality sign flips:
(-2k)/(-2) > 18/(-2)
k > -9

A sum of N$2 500 was deposited in a venture account, which pays 12% compounded per year and it accumulated to N$3 950. Calculate the number of years the amount has been in the venture account. Answer must be rounded to the nearest unit?
The number of years the amount has been in the venture account with 12% interest per year is 4.
What is compound interest?Compound interest is the interest on a loan or deposit calculated based on the initial principal and the accumulated interest from the previous period.
A sum of $2,500 was deposited in a venture account, which pays 12% compounded per year and it accumulated to $3,950.
Then the number of the years will be
We know the compound interest formula
[tex]\rm A = P(1+r)^t[/tex]
where
A = Accumulated amount
P = Deposited value
r = rate of interest
t = time
Then we have
[tex]3950 = 2500 (1.12)^t\\\\1.58\ =1.12^t[/tex]
Taking log both sides, then we have
[tex]\rm \ln 1.58 = t \times \ln 1.12\\\\or \ \ \ \ t = 4.036 \approx 4 \ years[/tex]
Then the number of the years is 4.
