Answer 1

Answer:

How to find a solution in an equation:

(1) Substitute the number for the variable in your equation,

(2) Simplify the expressions on both sides of your equation and

(3) Determine whether the resulting equation is true. If it is true, the number is a solution. If it is not true, the number is not a solution.

Step-by-step explanation:

If any questions, please ask them below.

Answer 2
We have 4 ways of solving one-step equations: Adding, Substracting, multiplication and division. If we add the same number to both sides of an equation, both sides will remain equal. If we subtract the same number from both sides of an equation, both sides will remain equal.

Answer:

m = 10

Step-by-step explanation:

The triangles are similar. The scale factor is 15/9.

We multiply 6 by the scale factor and get m:

m = 6 * 15/9 = 10

Then we see that m (10) is also the lenght of a side in the smaller triangle, so we multiply 10 by 15/9 and find a.

a = 16,6 (circa)

Four interior angles of a pentagon measure 88°, 118°, 132°, and 100°. What is the measure of the fifth interior angle? 82° 92° 102° 112°.

Answers

The measure of the fifth interior angle is 102 degrees.

A polygon is an object with five sides. It is made up of five straight edges and 5 interior angles. The sum of interior angles is 540 degrees.

In order to determine the fifth interior angle, the sum of the four interior angles would be subtracted from  sum of interior angles in a polygon.

Fifth interior angle = 540 - (88 + 132 + 100 + 118)

= 540 - 438

= 102 degrees

Question 16:

That means [tex](x-\alpha )(x-\beta ) = 2x^{2} -6x+5 = 0\\[/tex]

[tex](x-\alpha )(x-\beta ) = 2x^{2} -6x+5 = 0[/tex]

          [tex]2x^{2} -6x+5 = 0\\x^{2} -3x+\frac{5}{2} =0[/tex]

          [tex](x-\alpha )(x-\beta ) =x^{2} - (\alpha +\beta )x +\alpha \beta[/tex]

So,

Step-by-step explanation:

1) It appears that coordinates of points on line P are (-6, 6) and (-2, 8). The slope formula tells us the slope of line P is ...

  m = (y2 -y1)/(x2 -x1) = (8 -6)/(-2 -(-6)) = 2/4 = 1/2

Coordinates on line O appear to be (0, 6) and (4, 8). Its slope is ...

  m = (8 -6)/(4 -0) = 2/4 = 1/2

The slopes of lines P and O are the same, so the lines are parallel.

__

2) It appears that points on line M are (0, 6) and (2, 2). Its slope is ...

  m = (2 -6)/(2 -0) = -4/2 = -2

Points on line K appear to be (0, 4) and (10, 10). Its slope is ...

  m = (10 -4)/(10 -0) = 6/10 = 3/5

If lines M and K were perpendicular, the product of their slopes would be -1. Here, it is (-2)(3/5) = -6/5 ≠ -1. Lines M and K are not perpendicular.

During a sale, a store offered a 30% discount on a bed that originally sold for $580 After the sale, the discounted price of the bed was marked up by 30%. What was the price of the bed after the markup ? Round to the nearest cent .

Answers

The price of the bed after the markup is $527.80.

The given parameters:

Discount = 30%Price of the bed, = $580Markup = 30%

The price of the bed after the discount of 30% is calculated as follows;

P = $580 - 0.3($580)

P = $406

The price of the bed after the markup is calculated as follows;

P = $406 + 0.3(406)

P = $527.8

We evaluate an algebraic expression by the determination of an unknown variable.

Evaluation is a systematic method used in solving most algebraic expressions in mathematics.

Let assume that we have a given algebraic expression where y is expressed in terms of x and;

y = 2x + 5    where (x = 4)

Here, y and x are the variables;

At that time Puddleby was only quite a small town. A river ran through the middle of it; and over this river there was a very old stone bridge, called Kingsbridge, which led you from the market-place on one side to the churchyard on the other.Sailing-ships came up this river from the sea and anchored near the bridge. I used to go down and watch the sailors unloading the ships upon the river-wall. The sailors sang strange songs as they pulled upon the ropes; and I learned these songs by heart. And I would sit on the river-wall with my feet dangling over the water and sing with the men, pretending to myself that I too was a sailor.For I longed always to sail away with those brave ships when they turned their backs on Puddleby Church and went creeping down the river again, across the wide lonely marshes to the sea. I longed to go with them out into the world to seek my fortune in foreign landsAfrica, India, China and Peru! When they got round the bend in the river and the water was hidden from view, you could still see their huge brown sails towering over the roofs of the town, moving onward slowlylike some gentle giants that walked among the houses without noise. What strange things would they have seen, I wondered, when next they came back to anchor at Kingsbridge!
