Answer: Katie is 9 years old now. ✅
Step-by-step explanation:
By using the second equation, we can find that k = e+4,
then we can substitute k = e+4 into the first equation
k-9 = 2(e-9)
e+4-9 = 2(e-9)
e-5 = 2e-18
5 = e
so k = e + 4 = 5 + 4 = 9
Therefore, Katie is 9 years old now.

The quotient between the two fractions will give:
(4/6)÷(3/12) = 8/3
How to solve the quotient between two fractions?Here we want to find the quotient between the fractions 4/6 and 3/12.
The quotient between any two fractions a/b and c/d can be solved as:
(a/b)÷(c/d) = (a*d)/(b*c)
Then our quotient can be solved in the following way as:
(4/6)÷(3/12) = (4*12)/(3*6)
(4*12)/(3*6) = (48/18)
Now we can simplify that fraction, if we divide both numerator and denominator by 2, we will get:
24/9
Now we can divide both by 3, then we will get the simplified fraction:
8/3.
That is the correct answer.

Write two different equivalent forms of
the expression 2*x+3
On solving the question, The polynomial is 2x + 3 the equivalent forms are (4x- 2x + 3), (x + x +2 +1)
What is Equivalent Forms ?Expressions that are equivalent do the same thing even when they have distinct appearances. When we enter the same value(s) for the variable, two algebraic expressions that are equivalent have the same value (s).
Equivalent systems refer to sets of equations with the same solution. We can create an analogous system from a system of two equations by replacing one equation with the total of the two equations or by replacing an equation with a multiple of itself.
When two expressions can be reduced to a single third expression or when one of the expressions can be expressed in the same way as the other, they are said to be equivalent. When values are replaced for the variable and both expressions yield the same result, you may also tell if two expressions are equal.
The polynomial is 2x + 3
The equivalent forms are (4x- 2x + 3), (x + x +2 +1)

Even pound of fertilizer can cover 1400 quare feet how many quare feet can be covered by 2 pound of fetilizer
If seven pound of fertilizer can cover 1400 square feet, 2 pounds of fertilizer can cover 400 square feet.
Therefore the answer is 400 square feet.
If seven pounds of fertilizer can cover 1400 square feet, we can set up the following proportion:
7 pounds / 1400 square feet = x pounds / y square feet
So y square feet = ( x pounds × 1400 square feet) / 7 pounds
To find out how many square feet can be covered by 2 pounds of fertilizer, we can solve for y by substituting in 2 for x:
y square feet = ( 2 pounds × 1400 square feet) / 7 pounds
y square feet = 2 × 1400 / 7
y square feet = 2800 / 7
y square feet = 400
So 2 pounds of fertilizer can cover 400 square feet.

What is equation?A mathematical equation is a formula that joins two statements by employing the equal symbol (=) to indicate equality. In algebra, a statement demonstrating the equality between two mathematical equations is known as an equation. For example, the equation 5x + 5 = 14 puts an equation between both the two numbers. Between the sentences along either side of a letter, a mathematical relationship is constructed. Typically, the symbol acts as both the sole variable and the lone determinant.

One-step equations can be solved using any one of the following four methods: adding, subtracting, multiplying, or dividing. Both sides of an equation will stay equal if the same integer is added to both sides. A mathematical expression should be evaluated according to a rule known as the order of operations.
The PEMDAS acronym can help us recall the following in that order: parentheses, exponents, multiplication and division (left to right), addition and subtraction (from left to right).

What are the 4 steps in constructing perpendicular bisector?
The four steps in constructing a perpendicular bisector are follows.
Find the midpoint of the line segment: To find the midpoint of a line segment, take the average of the x coordinates and the average of the y coordinates. This can be written as a formula: M(x,y) = (x1 + x2/2, y1 + y2/2).
Find the slope of the line: To find the slope of the perpendicular bisector, take the negative reciprocal of the original line segment’s slope. This can be written as a formula: m = -1/m1, where m1 is the original line segment’s slope.
Find the equation of the line: To find the equation of the perpendicular bisector, plug in the slope and midpoint into the point-slope form of a line equation. This can be written as a formula: y – y1 = m(x – x1).
Construct the perpendicular bisector: To construct the perpendicular bisector, draw the line corresponding to the equation found in step 3. The line should be perpendicular to the original line segment, and should pass through the midpoint.

An= (4+3n^2)/(n+5n^2)
Lim n-> An =
To determine whether the sequence converges or diverges, we can use the Squeeze Theorem.
We can see that
[tex]4/(n + 5n^2) < = An < = (4 + 3n^2)/(n + 5n^2)[/tex]
As n tends to infinity, [tex]4/(n + 5n^2)[/tex] tends to 0 and[tex](4 + 3n^2)/(n + 5n^2)[/tex] tends to[tex]4/(5n^2)[/tex] which also tends to 0.
So by the Squeeze Theorem, we can say that An tends to 0 as n tends to infinity. Hence the limit of the sequence is Lim n-> An = 0
We can also see that the numerator of An is a constant and the denominator is a polynomial with degree 2. Since the denominator's degree is greater than the numerator, the limit will be zero as n -> infinity.
Therefore, the sequence converges to 0.

What is profit and loss?A product is sold at a profit if the price is higher than the cost price. When a product is sold for less than what it costs to produce, the seller suffers a loss.
Each bag contains 150g of sweets.
The total number of bags filled with a total of 3kg sweets can be calculated as follows:
3kg = 3000g
Number of bags = [tex]\frac{3000}{150}[/tex] = 20 bags

The Cost price, CP = 17.60 and profit is 35%, substitute the value in the formula above:
[tex]35 = \frac{SP - 17.60}{17.60} *100\\ \\\frac{(35)(17.60)}{100} = SP - 17.60\\\\6.16 = SP -17.60\\\\6.16 + 17.60 = SP\\\\SP= 23.76[/tex]

bagel: $3OJ: $2Step-by-step explanation:
You want the price of a bagel and a can of OJ if 2 bagels and 1 can costs $8, and 3 bagels and 2 cans cost $13.
EquationsYou can write an equation for the value of each purchase. The cost of a bagel can be represented by 'b', and 'j' can be used for the cost of an orange juice.
2b +1j = 83b +2j = 13SolutionThe coefficients of j are related by a factor of 2, so we can make the sum of coefficients of j be zero if we subtract the second equation from 2 times the first:
2(2b +1j) -(3b +2j) = 2(8) -(13)
b = 3 . . . . . . . . . . . . . . simplify
Now, we can use this value in the first equation to find j:
2(3) +1j = 8
1j = 2 . . . . . . . . . subtract 6
A bagel costs $3, and a can of orange juice costs $2.
