Solve. 38 – 2x = 6 22 16 –16 –22
Answer:
16
Step-by-step explanation:
38 - 2x = 6 [subtract 38 from both sides]
-2x = -32 [divide by -2 to isolate x]
x = 16
The student council has $800 to spend on homecoming t-shirts. The number of t-shirts they can buy is a function of the price of the price of the t-shirt p, in dollars, given by n(p)= 800 over p.
Answer:
the price of the t-shirt is inversely proportional to the number of t-shirts to be bought.
Step-by-step explanation:
The total amount to be spent on t-shirts is $800.
The function;
n(p) = 800 / p (price in dollars)
as the price per shirt increases, the number of shirt decreases and the curve moves down towards zero. When the price per shirt decreases, the number of shirt increases moving the curve upwards to infinity
Can someone tell me if this is correct and if not tell me how to put it plzzzzzzzz

Mei releases a lantern for the Lantern Festival. She stands in a field that is 0.5 m belo sea level. The lantern rises 913.9 m. Then the candle in the lantern goes out. The lantern comes down 925.2 m to land on the surface of a lake. What is the elevation o the lake relative to sea level?
Answer:
The lake is 11.3 m below sea level.
Step-by-step explanation:
Mei's initial position on the field was 0.5 m below sea level.
The lantern rises 913.9 m after its release.
The lantern descends 925.2 m to land on the surface of a lake.
Let the elevation of the lake to sea level be represented by x.
So that;
x = 913.9 - 925.2
= -11.3
x = 11.3 m below sea level.
Therefore, the lake is 11.3 m below sea level.

three less than twice the sum of a number,x, and seven is four
Answer:
The answer is 3
Hope this helps
Step-by-step explanation:
Answer:
The second one
Step-by-step explanation:
3 less than means we subtract 3 from the number.
Twice the sum of x and 7 is 2(x + 7)
Put them together and get 2(x + 7) - 3 = 4

The price of the house decreases from $250,000 in 2005 to
$195,000 in 2010. What is the average rate of change for the
house each year?
Answer:
The average rate will be -11000 dollars per year.
Step-by-step explanation:
The price of a house in 2005 = $250,000
The price of a house in 2010 = $195,000
at x₁ = 2005, f(x₁) = 250,000
at x₂ = 2010, f(x₂) = 195,000
Using the formula to determine the average rate of change for the
house each year.
Average rate = [f(x₂) - f(x₁)] / [ x₂ - x₁]
= [195,000 - 250,000 ] / [2010-2005]
= -55000 / 5
= -11000
Therefore, the average rate will be -11000 dollars per year.
FUNDRAISING The baseball team plans to sell tins of popcorn and peanuts. The players have $900 to spend on products and can order up to 200 tins. They want to order at least as many tins of popcorn as tins of peanuts. A tin of popcorn costs $3, and a tin of peanuts costs $4. Define the variables and write a system of inequalities to represent this situation. Then list any constraints for the variables.
the constraints for the variables is 2
The required inequality is given as 3x + 4y ≤ 900.
Given that,
The baseball team plans to sell tins of popcorn and peanuts. The players have $900 to spend on products and can order up to 200 tins. They want to order at least as many tins of popcorn as tins of peanuts. A tin of popcorn costs $3, and a tin of peanuts costs $4.
Inequality can be defined as the relation of the equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.
Let, the number of pop-corn tin be x and the number of peanuts tin be y,
According to the question,
Cost of the x tin of popcorn = 3x
Cost of the y tine of peanuts = 4y
Now the sum of the cost of popcorn and peanuts must no exceed $900,
So
3x + 4y ≤ 900
Thus, the required inequality is given as 3x + 4y ≤ 900.

What is the equation to 5 less than the product of a number squared and 8
Answer:
8n² - 5Step-by-step explanation:
5 less than the product of a number squared and 8, translating the expression:
n²*8 - 5=8n² - 52x-8y=16 solve for x
Answer:
x=8+4y
Step-by-step explanation:
Add 8y to both sides:
2x=16+8y
Divide both sides by 2:
x=8+4y

Answer:
A, 14
Step-by-step explanation:
Assuming that she has a total of d dollars, and spends half of it, then we have 1/2d. She then spends another 6 dollars, and therefore we would subtract. She is left with one dollar.
1/2d-6=1
Working backwards, we can solve for d, her total amount of money:
1/2d=7
d=14

John is two years younger than his sister, Annie. Last year, John was half Annie's age. How old are John and Annie now?
Answer: John is 3 and Annie is 5
Step-by-step explanation:
because to be half of someone's age while being to years younger it would have to be 2 and 4 - but then a year passed and so the are now 3 and 5.
Answer: John is 3 and Annie is 5
Step-by-step explanation:
Half of 4 is 2 so last year John was 2 and Annie 4 and like a year has passed we add 1 to 2 and 4 which helps us determine that John is now 3 and Annie 5

If two sides of a triangle are 5 and 8. The possible third side is
Answer:
12
Step-by-step explanation:
Since 5+8=13, it has to be less than 13. The greatest possible perimeter is 25.
This means that 12 could be a possible side length for the third side.

Please can you help me answer this
Answer:
a) The factors of x² + 3·x are x and (x + 3)
x² + 3·x = x·(x + 3)
b) The factors of 2·x² - 8·x are 2, x and (x - 4)
2·x² - 8·x = 2·x·(x - 4)
c) The factors of 6·x + 9·x³ are 3, x and (2 + 3·x²)
6·x + 9·x³ = 3·x·(2 + 3·x²)
d) The factors of 12·x³ - 4·x² are 4, x², and (3·x - 1)
12·x³ - 4·x² = 4·x²·(3·x - 1)
Step-by-step explanation:
The question relates to resolving a polynomial into its factors;
a) For the polynomial (quadratic) equation, x² + 3·x, we have;
x² + 3·x = x·(x + 3)
Therefore, x² + 3·x in factorized form is x·(x + 3)
b) For the polynomial (quadratic) equation, 2·x² - 8·x, we have;
2·x² - 8·x = 2·x·(x - 4)
Therefore, 2·x² - 8·x in factorized form is 2·x·(x - 4)
c) For the polynomial (cubic) equation, 6·x + 9·x³, we have;
6·x + 9·x³ = 3·x × (2 + 3·x²)
Therefore, 6·x + 9·x³ in factorized form is 3·x·(2 + 3·x²)
d) For the polynomial (cubic) equation, 12·x³ - 4·x², we have;
12·x³ - 4·x² = 4·x²·(3·x - 1)
Therefore, 12·x³ - 4·x² in factorized form is 4·x²·(3·x - 1).
