1 answer:

6 0

5x-12=3x

Let's solve your equation step-by-step.
5x−12=3x
Step 1: Subtract 3x from both sides.
5x−12−3x=3x−3x
2x−12=0
Step 2: Add 12 to both sides.
2x−12+12=0+12
2x=12
Step 3: Divide both sides by 2.
2x/2=12/2

x=6

If you eat a diet with 2,000 kilocalories and 45 percent of those calories come from protein, about how many grams of protein di

jekas [21]

The amount of Protein intake is 900 kilocalorie.

We have - 2000 Kilocalories of diet and 45 Percent of calories come from Proteins.

Wе have to find out the amount of protein intake.

<h3>If ' x ' students out of total ' n ' students in a class are infected by virus. Then, what percentage of students are infected.</h3>

Percentage of students affected are - $\frac{x}{n} \times 100$

In the question given -

Let the amount of Protein intake be y.

Then -

45 = y % of 2000

45 = $\frac{y}{2000} \times100$

y = $\frac{45\times2000}{100}$

y = 900 Kilocalorie

Hence, the amount of Protein intake is 900 kilocalorie.

You are in talks to settle a potential lawsuit. The defendant has offered to make annual payments of $15,000, $25,000, $40,000,

Sphinxa [80]

Answer:

All payments will be made at the end of the year by using the present value of inflows

Step-by-step explanation:

Present Value Of Inflows = Cash Inflow × Present Value Of Discounting Factor (Rate%,Time Period)

Present Value Of Inflows = $15000/1.037$ + $25000/1.037^{2}$ + $40000/1.037^{3}$ + $60000/1.037^{4}$

Present Value Of Inflows = 125466.3

How many different triangles can be constructed with three sides, each measuring 5 centimeters?

Akimi4 [234]

The first thing we will do is define an equilateral triangle:
In geometry, an equilateral triangle is a regular polygon with three equal sides. In traditional Euclidean geometry, equilateral triangles are also equiangular, that is, the three internal angles are also congruent to each other, each angle with a value of 60 °
Every equilateral triangle consists of three equal sides and three congruent angles.
Therefore, there can be a triangle with three equal sides (5 centimeters in this case).
Answer:
1) one

Suppose A is an invertible n×n matrix and v is an eigenvector of A with associated eigenvalue 4. Convince yourself that v is an

mote1985 [20]

The eigenvector of matrix A4 is 4096.

The eigenvalue of the matrix A-1 is 1/8.

(A+4I) has an eigenvalue of 12.

40 is the eigenvalue of 5Av.

The collection of scalar values known as the eigenvalues of a matrix are connected to the set of linear equations that are most likely contained within the matrix equations.

The eigenvectors are also known as the characteristic roots.

If the matrix A's eigen vector v is linked to an eigen value.

Av then equals lamda v.

The fact that v is an eigen vector of A with the value eight is assumed.

hence, Av = 8v.

We must determine the eigenvalue of A4.

A4*v equals A3(8v) = 84*v equals 4096v.

As a result, the eigenvalue of A4 is 4096.

Suppose A has an eigenvalue of 8. The eigenvalue of A-1 is thus 1/8.

It is calculated that the eigenvalue of (A+4I) is (A +4In)v = Av + 4v = 8v + 4v =12v.

(A+4I) has an eigenvalue of 12.

The value of 5Av's eigenvalue is 5Av = 5*8v = 40v.

40 is the eigenvalue of 5Av.
