Answer: To solve the inequality 1/4b−1/5b > 3/10b−1/2, we need to simplify both sides:
1/4b - 1/5b > 3/10b - 1/2
5/20b > 7/20b
Then we isolate b by subtracting 7/20b from both sides:
-2/20b > -7/20
Finally, we divide both sides by -2/20 to get:
b < 35/2
The solution in interval notation is (-∞, 35/2).

Solve for x. 8x-8+3(2x+2) = -4(x+3)
Answer:
x = - 5/9
Step-by-step explanatiion:
8x-8+3(2x+2) = -4(x+3) is the original equation
Consider each term and simplify
3(2x+2) = 6x + 6
-4(x + 3) = -4x - 12
Therefore the original expression becomes:
8x - 8 + 6x + 6 = -4x - 12
Move -4x to the left side; becomes + 4x
4x + 8x - 8 + 6x = -12
Group like terms on left side and simplify
(4x + 8x + 6x) (-8 +6) = -12
18x - 2 = - 12
Move -2 to right side -> becomes +2
18x = 2 - 12 = - 10
x = -10/18 = - 5/9

What is a Linear equation?A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. Sometimes, the aforementioned is referred to as a "linear equation of two variables," with y and x serving as the variables.
Given this, Kaya babysits to add money to her savings. She draws a graph to show how much she can earn by babysitting.
To calculate the equation of the line we at least need Two points on the line.
Two points on the graph (0, 25) and (5, 100) and also the y-intercept of the given line is 25(where x is 0)
From the general formula of the slope-intercept form of an equation:
y=mx+b,
where m is the slope
b is the y-intercept,
Since. m = (y - y')/ (x -x')
In our case m = (100 - 25)/5-0)
m = 75 /5
m = 15
and b = 25
Thus, the equation of a line:
y = 15x + 25
Therefore, The equation of the line of Kaya’s line in slope-intercept form is y = 15x + 25.

The values will be Loan amount=$186900, When simple interest is 6% then monthly payment=$1453.66 per month, When simple interest is 7% monthly payment=$1609.4 per month
What is simple interest?Simple Interest is an easy method of calculating the interest for a loan/principal amount. Simple interest is a concept that is used in many sectors such as banking, finance, automobile, and so on. When you make a payment for a loan, first it goes to the monthly interest and the remaining goes towards the principal amount.
Simple interest formula is given as:
SI=P*R*T/100
Where SI = simple interest
P = principal
R = interest rate (in percentage)
T = time duration (in years)
In order to calculate the total amount, the following formula is used:
Amount (A) = Principal (P) + Simple Interest (SI)
Now,
Initial amount=$237000
Down-payment=20%=20/100*237000=$47400
Amount left=237000-47400=$186900
So, Loan amount=$186900
For interest rate=6%
Total amount=186900+186900*6*30/100
=186900+336420
Total amount=$523320
Therefore, monthly payment=523320/360
monthly payment=$1453.66 per month
For interest rate=7%
Total amount=186900+186900*7*30/100
=186900+392490
Total amount=$579390
Therefore, monthly payment=579390/360
monthly payment=$1609.4 per month

What is a slope?In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction.
Given:
A line has a slope of –9 and includes the points (–7,u) and (9,9).
If a line passes through two points (x₁ ,y₁) and (x₂, y₂) ,
then the equation of line is
y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)
To find the slope;
m = (y₂- y₁) / (x₂ - x₁)
-9 = (9 - u)/(9 + 7)
-9 = (9- u)/16
9 - u = -144

I did number one but i think its wrong
Answer: A: 3/10 of the school has blonde hair. B: there are 120 students
Step-by-step explanation: I might have done this wrong but anyway, I multiplied 2/5 by 1/4 and got 1/10, meaning 1/10 of the boys have blonde hair. I multiplied 3/5 (because 5/5 - 2/5 = 3/5) by 1/3 and got that 2/10 of the girls are blonde. I added these, and got that 3/10 of the school are blondes. That's A. Then, I set up the equation 3/10 = 36/x (x equals the total number of students in the school). When I solved it I got x = 120, meaning there are 120 students in the school.

1a. In a class of 58 students, 35 offer Biology, 28 offer Economics and 15 offer Physics. Each
students offers at least one of the three subjects. If 12 students offer both Biology and
Economics, 7 students offer both Biology and Physics and 5 students offer both Economics and
Physics, how many students offer all three subjects?
b. A regular polygon with (2m+1) sides has each interior angle equal to 1440. Find the value of
m.
A. 9 students offer all three subjects.
B. The only possible value of m is 8.
Solution
A. We can use the Principle of Inclusion-Exclusion (PIE) to find the number of students who offer all three subjects.
Let's call the number of students who offer all three subjects "x".
The total number of students who offer Biology is 35, but we have to subtract the number of students who offer only Biology and Economics (12) and only Biology and Physics (7) to avoid counting them twice.
So, the number of students who offer Biology only is 35 - 12 - 7 + x = 16 + x.
Similarly, the number of students who offer Economics only is 28 - 12 - 5 + x = 11 + x.
And the number of students who offer Physics only is 15 - 7 - 5 + x = 3 + x.
The total number of students who offer at least one of the three subjects is 58, so:
16 + x + 11 + x + 3 + x = 58
30 + 3x = 58
3x = 28
x = 9
So, 9 students offer all three subjects.
B. In a regular polygon with (2m + 1) sides, each interior angle is equal to (2m + 1 - 2) * 180 / (2m + 1) = (2m - 1) * 180 / (2m + 1).
We know that this value is equal to 1440, so:
(2m - 1) * 180 / (2m + 1) = 1440
Expanding the right side:
2m - 1 = 1440 * (2m + 1) / 180
Dividing both sides by (2m + 1) and rearranging:
2m = 1440 * 2 / 180 + 1
2m = 16 + 1
m = 8.5
Since m must be a positive integer, the only possible value of m is 8.

Step-by-step explanation:
Step-by-step explanation:
first step : convert both terms into real fractions (not mixed numbers).
second step : bring both fractions to the same denominator (bottom part).
third step : perform the addition.
1.
2 2/3 = (2×3 + 2)/3 = 8/3
2 1/6 = (2×6 + 1)/6 = 13/6
2.
we bring both fractions to .../6.
remember, we need to do the same multiplication for the numerator and the denominator to keep the overall value of the fraction unchanged.
to get from 3 to 6 we need to multiply by 2.
so,
8/3 = 8/3 × 2/2 = 16/6

16/6 + 13/6 = 29/6

On solving the provided question, we can say that so, the Interest Rate to be paid will be as = 5.08%
what is interest ?Simple interest is calculated by dividing the principal by the interest rate, the passage of time, and other elements. The formula used in marketing is simple return = principal + interest + hours. Using this approach, interest may be calculated most easily. The most common way to calculate interest is as a percentage of the principal balance. If he borrows $100 from a friend and agrees to pay it back with 5% interest, for instance, he will only pay his proportion of the 100% interest. $100 (0.05) = $5. You must pay interest when you borrow money and charge interest when you lend it. The majority of the time, interest is calculated as an annual percentage of the loan balance. This proportion is referred to as the loan's interest rate.
Interest Rate =($ Paid in Interest / $ Amount borrowed) X (360 / borrowed period)
= ($33 / $2600) X (360 /90)
