Answer:

1. 0.82x

2. 1.18x

3. (7/10)x

4. (3/10)x

Step-by-step explanation:

When something is discount off 18 percent, it lowers the orginal price by 18 percent. Pretend the original price is x. Taking out 18 percent would be 0.82x

Same thing. 18 percent more, would be 1.18x since instead of subtracting, you add. 1.18x

3/10 in percent form is 30 percent. 100 - 30 = 0.7 so 0.7x

Since it has 3/10 <em>of </em> the orginal, it is multiply. If the orginal is x, x * 3/10 = (3/10)x.

What we do in Evaluation in math?

The verb "evaluate" is used in mathematics to mean to discover or determine the worth of something. Finding the precise value of an algebraic expression or numerical computation is relevant here as well as financial mathematics.

In mathematics, the terms "evaluate" and "solve" are often used interchangeably. Consider the following basic multiplication problem: "Evaluate the cost of six tomatoes when the tomatoes are purchased at $2 each." The student would multiply 6 by 2 to get the result of $12. The term evaluate might also come before a list of inquiries, as a list of straightforward algebraic equations.

If 0.142857142857......is expressed in the form m/n, then what is the value<br>of (2m + n)?

frosja888 [35]

Answer:

The value will be: 1,285,713

Step-by-step explanation:

We have the number:

N = 0.142857...

Such that we have 6 decimals after the decimal point that repeat infinitely.

Then let's start by multiplying our number by 1,000,000 (same number of zeros as decimals after the decimal point)

Then we get:

1,000,000*N = 142,857.142857...

Now let's subtract N from both sides:

1,000,000*N - N = 142,857.142857... - 0.142857...

999,999*N = 142,857

Now let's isolate N

N = 142,857/999,999

Here is our number expressed in the form m/n, where:

m = 142,857

n = 999,999

Then the value of (2*m + n) is:

(2*142,857 + 999,999) = 1,285,713

1.When all the three cut outs of the angles A, B, C placed adjacent to each other at a point, then it forms a line forming a straight angle, i.e. 180°.

Flence, it is proved that the sum of the three angles of a triangle is 180°.

Therefore, ∠A + ∠B + ∠C =180
