Stephanie purchased seven note books for 12.25. What is the cost of per notebook
Answer:
1 dollar 75 cents or $1.75
Step-by-step explanation:
can this problem be solved?
Answer:
The discriminant is -23
The equation has 0 real solution
Step-by-step explanation:
The discriminant of the quadratic equation ax² + b x + c = 0 is Δ = b² - 4ac
If Δ > 0, then the equation has two different real solutionsIf Δ = 0, then the equation has one real solutionIf Δ < 0, then the equation has no real solutionsLet us use the rule above to solve the question
∵ x² - x + 6 = 0
∴ a = 1, b = -1 and c = 6
∵ Δ = b² - 4ac
∴ Δ = (-1)² - 4(1)(6)
∴ Δ = 1 - 24
∴ Δ = -23
∴ The discriminant is -23
∵ -23 < 0
∴ Δ < 0
∴ The equation has no real solutions
∴ The equation has 0 real solution

Leon packs thirty business envelopes in each of twenty-five boxes and thirty regular envelopes in each of twenty boxes. How many envelopes does he pack?
Answer: 1350 envelopes
Step-by-step explanation:
From the question, Leon packs thirty business envelopes in each of twenty-five boxes. The total business envelopes here will be:
= 30 × 25
= 750
Leon picked thirty regular envelopes in each of twenty boxes. The total regular envelopes will be:
= 30 × 20
= 600
Total envelopes will now be:
= 750 + 600
= 1350 envelopes
evaluate b(x)=18-0.5x when x= -2,0, and 5.
Answer:
19, 18, 15.5
Step-by-step explanation:
b(-2) =
18 - 0.5(-2)
18 - (-1)
b(x) = 19
b(0) =
18 - 0.5(0)
18 - 0 =
b(x) = 18
b(5) =
18 - 0.5(5)
18 - 2.5
b(x) = 15.5

Point L is on line segment \overline{KM}
KM
. Given LM=3x+3,LM=3x+3, KM=5x+4,KM=5x+4, and KL=5x+1,KL=5x+1, determine the numerical length of \overline{KM}.
KM
.
Answer:
KM = 4 units
Step-by-step explanation:
Here, we are to determine the numerical length of KM
since point L is on the line segment;
Then;
KM = KL + LM
Thus;
5x + 4 = 5x + 1 + 3x + 3
5x + 4 = 8x + 4
8x - 5x = 4-4
3x = 0
x = 0/3 = 0
From the question;
KM = 5x + 4
Substitute x = 0
Thus we have;
5(0) + 4 = 4
KM = 4 units

N the United States, the average public school teacher currently earns an annual salary near $55,202. Reported national average salaries for the last six decades are listed below. Year National Average Teachers' Salary 1960 $4,995 1970 $8,626 1980 $15,970 1990 $31,367 2000 $41,807 2010 $55,202 Determine the average salary increase per year between the years 1980 and 1990. $1,539.70 $8,367.80 $2,566.20 $1,004.10
Answer:
$1,539.70
Step-by-step explanation:
Given the data :
National average Teachers' salary (NATS)
YEAR:_1960 _ 1970 _ 1980 _ 1990 _ 2000 2010
NATS:4995_8626_15970_31367_41807_55202
AVEAGE SALARY INCREASE PER YEAR BETWEEN 1980 and 1990
Salary in 1980 = $15970
Salary in 1990 = $31367
Average salary increase per year:
Difference in salary / difference in years
$(31367 - 15970) / (1990 - 1980)
= $15397 / 10
= $1539.7
54x + 15 = -3 (3y + 1)
I need help finding the equation for y
Answer: y = -6x - 2
Step-by-step explanation:
54x + 15 = -3(3y + 1) To solve for y distribute on the right side to get,
54x + 15 = -9y -3 Add 3 to both sides
+3 +3
54x + 18 = -9y Divide each term by -9 on each side.
y = -6x - 2
Answer______
54x + 15 = -3 (3y + 1)
54x + 15 = -9y -3
+3 +3
54x + 18 = -9y
y = -6x - 2

Darlene purchases 20,000 worth of stock on her brokers advice and pays her broker a 1.5% broker fee darlene purchases 20,000 worth of stock on your brokers advice and pays her broker a 1.5% broker freeshe sells her stock when it increases to $28,600.02 years later and uses a discount broker who charges $21 per trade compute Darlenes net proceeds after the broker fees are taken out
Answer:
Darlene's net proceeds after the broker fees are taken out is $8,279.
Step-by-step explanation:
From the question, the following can be obtained:
Basic cost of purchase of the stock = $20,000
Broker fee related to purchase = Basic cost of purchase of the stock * 1.5% = $20,000 * 1.5% = 300
Total cost of purchase of the stock = Basic cost of purchase of the stock + Broker fee related to purchase = $20,000 + 300 = $20,300
Selling price = $28,600
Broker fees related sales = 21
The net proceed can therefore be calculated as follows:
Net proceeds = Selling price - Broker fees related sales - Total cost of purchase of the stock = $28,600 - $21 - $20,300 = $8,279
Therefore, Darlene's net proceeds after the broker fees are taken out is $8,279.

Answer:
4/13 < 6/13
Step-by-step explanation:
I will assume you want to see which one is greater.
We don't need to find common denominators since they already have one which is 13.
We know that 4 < 6 so this means that 4/13 < 6/13
