5 is the difference between the two numbers 12 and 7.
Given,
In the question;
The difference between 3 times a number and 7 is 5.
Write and solve an equation to determine the number.
Now, According to the question:
Let's assume the unknown number to be x,
so three time the number would be 3x.
The difference between 3 times a number (3x) with 7 is 5, so we can write it as:
3x - 7 = 5
Now we can solve this equation to the find x (the unknown number).
3x = 5 + 7
3x = 12
x = 12/3
x = 4
Therefore 3x= 12
So, 5 is the difference between the two numbers 12 and 7.

Mary Granola consumes tomatoes and nectarines. Mary's indifference curves are kinky. When she is consuming more tomatoes than nectarines, she is just willing to trade 3 tomatoes for 1 nectarines. When she is consuming more nectarines than tomatoes, she is just willing to trade 4 nectarines for 1 tomatoes. Let P₁ be the price of nectarines and P₂ the price of tomatoes. Mary maximizes her utility subject to her budget constraint. Which is true? (Hint: Sketch one of her indifference curves.)
When P₁ >3P₂ she must consume only tomatoes.
What are indifference curves ?
An indifference curve is a graph that illustrates numerous pairings of two goods or commodities that leave the customer equally well off or satisfied—hence indifferent—when it comes to owning any pairing of the two items that is represented along the curve.
Mary do trading 3 tomatoes for 1 nectarine.
So, MRS=3
P₁ >3P₂
P₁/P₂ > 3
P₁/P₂ < -3
This satisfies MRS=3
P₁ >3P₂ shows budget constraint
consumer specializes in tomatoes consumption.
if P₂ > 4 P₁ , consumer specializes in nectarine consumption. option is not there.

What is a trinomial?One or more terms in an algebraic expression each include variables and constants. These expressions utilize separators like +, -, and that are symbols or operations. An algebraic statement with variables and constants is a quadratic trinomial. It is written as ax² + bx + c, where a, b, and c are real non-zero values and x is the variable. The leading coefficient "a," linear coefficient "b," and additive constant "c" all refer to the same constant.

Evaluate the Laplace transform of L[(sin 2t-cos 2t)^2]
The Laplace transform of the given integral function is 1/s +4 / (s²+16) .
The integral transform, commonly known as the Laplace transform in mathematics, converts a function of either a real variable t in the time domain into a function of something like a complex variable s.
The Laplace transform is equal to the integral for the suitable functions
[tex]{\displaystyle {\mathcal {L}}\{f(t)\}(s)=\int _{0}^{\infty }f(t)e^{-st}\,dt.}[/tex]
Now we will use this to find the suitable Laplace transform of the trigonometric function:
(sin 2t-cos 2t)²
= sin² 2t + cos² 2t - 2sin 2tcos 2t
= 1 - sin 4t
Now we will use the Laplace transform of the function.
L [1 - sin 4t] = L[1] - L[sin 4t]
Now L[1] = 1/s
L[sin 4t] = 4/ (s²+4²) = 4 / (s²+16)
Hence the Laplace transform will be
L [1 - sin 4t] = 1/s +4 / (s²+16)
Pierre-Simon Laplace invented the complex frequency domain, often known as the s-domain or the s-plane. There are numerous uses for the transform, a method for solving differential equations, in both science and engineering.

m = 13
Applying the definition of exterior angle of a triangle, the value of m is: m = 32.
What is an Exterior Angle of a Triangle?An exterior angle of a triangle can be defined as the angle formed outside the triangle when one of its side is extended.
The exterior angle to an interior angle, is supplementary to the interior angle. That is, they have a sum of 180 degrees when we add their angle measures together.
Given the following:
Measure of angle Z = 4m - 15
Measure of the exterior angle to angle Z = 2m + 3
Therefore:
4m - 15 + 2m + 3 = 180
Combine like terms
6m - 12 = 180
6m = 180 + 12

Henry invested $1500 into an account that pays 2% interest compounded annually.
How much money will Henry have at the end of 3 years?
Enter your answer in the box. Round to the nearest hundredth.
The compound interest is obtained as $91.81, rounded off to the nearest hundredth.
How is compound interest estimated annually?In order to compute compound interest, multiply the principle of the original loan by the annual interest rate multiplied by the number of compound periods minus one. You will then be left with the principal amount of the loan plus compound interest. The entire compound interest is then obtained by deducting the initial principal.
The equation that results will look like this:
Compound Interest = [tex]P(\left(1+r\right)^{ t}-1)[/tex]
Amount, rate of interest and time is given as $1500, 2% and 3 years respectively.
First, change r as a percent to r as a decimal.
r = R/100
r = 2/100
r = 0.02 rate per year,
Then solve the equation for compound interest.
[tex]\text{Compound Interest}=1500(\left(1+0.02\right)^{3}-1)\\=1500(1.061208-1)\\=15000\cdot 0.061208\\\\=91.81[/tex]
