Answer:

This is a simple algebraic equation, it can be solved by isolating the variable on one side of the equation.

-2.75x + 7 = -26

Add 26 to both sides of the equation:

-2.75x + 33 = 0

Divide both sides by -2.75:

x = -12

So the solution of the equation is x = -12.

Note that x = -12 is the value of x that makes the equation true

Answer:

x = 12

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

x = 12

[tex](x+1)(x-2)(x-4)[/tex]

Step-by-step explanation:

By the Rational Root Theorem, possible rational solutions for the given polynomial are [tex]\pm1,\pm2,\pm4,\text{ and}\pm8[/tex], so we can test each one:

1 |  1  -5   2   8

____ 1_-4_-2

    1  -4  -2 | 6 <-- (x-1) IS NOT a root

-1 |  1  -5   2    8

____-1_ 6_ -8

     1  -6   8  | 0 <-- (x+1) IS a root

So, [tex]x^3-5x^2+2x+8=(x+1)(x^2-6x+8)=(x+1)(x-2)(x-4)[/tex]

So, 30 and 5 are the values that are missing is calculated by ratio and proportion.

An ordered pair of numbers a and b, written as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. For instance, you could write the ratio as follows: 1: 3 if there is 1 boy and 3 girls (for every one boy there are 3 girls)

If both the antecedent and the consequent are multiplied or divided by the same non-zero number, the ratio remains the same.

The complete question is given below.

Answer:

Takes maria

Step-by-step explanation

Maria's rate of speed is 46.5 kilometers per hour.

What is the distance?

Distance is defined as the product of speed and time.

Since there are 3600 seconds in an hour, we can divide the time it takes Gretchen to travel 4400 meters by 3600 to find the number of hours it takes her:

⇒ 340 seconds / 3600 seconds/hour = 0.09444444 hours.

Next, we need to convert the distance she travels to kilometers. Since there are 1000 meters in a kilometer, we can divide the distance Maria travels by 1000 to find the number of kilometers she travels:

⇒ 4400 meters / 1000 meters/kilometer = 4.4 kilometers.

Now that we have the distance Maria travels and the time it takes her to travel that distance in the appropriate units, we can divide the distance by the time to find her rate of speed in kilometers per hour:

⇒ 4.4 kilometers / 0.09444 hours = 46.5882375  kilometers/hour.

Thus, Maria's rate of speed is 46.6 kilometers per hour.

The inverse additive of 2 3 is -2 3.. This means that when you add the two numbers together, the result is 0.

2 3 + (-2 3)

= (2 x -1) + (3 x -1)

= -2 + (-3)

= -5

= 0

The additive inverse of 2 3 is -2 3. In mathematics, an additive inverse is a number that when added to another number will produce a result of zero. This means that when you add 2 3 and -2 3 together, the result will be 0. To calculate this, we first start by multiplying each number by its opposite sign. So,

2 x -1 = -2 and

3 x -1 = -3.

Then, we add the two numbers together

: -2 + (-3) = -5.

Finally, we simplify the equation to 0. The additive inverse of 2 3 is -2 3, meaning that when added together, the result will be 0.

The selling price of the washer/dryer is $1,137.86. Thus, the correct answer is option b.

To find the cost of the washer/dryer, we need to reverse the markup percentage. We can do this by dividing the markup by 100 and then multiplying by the selling price.

Markup = (Markup Percentage) x (Cost)

So, if we rearrange this equation and solve for cost:

Cost = (Markup) / (Markup Percentage)

Plugging in the given information:

Cost = $295.00 / 0.35

Cost = $842.86

To find the selling price, we add the markup to the cost:

Selling Price = Cost + Markup

Selling Price = $842.86 + $295.00

The area of mathematics known as trigonometry examines the correlation between triangle side lengths and angles. The area first appeared in the Hellenistic era, around the third century BC. from the use of geometry in astronomical study. The area of mathematics known as exact methods deals with specific trigonometric functions and how they might be used in calculations.

To find the length of TR, we can use the ratio of similarity between the two triangles. Since triangle NOP is similar to triangle RST, we know that the ratio of the corresponding sides is equal. In this case, we can set up the proportion:

(TR)/(NO) = (TS)/(OP)

We know that NO = 34 and OP = 19, and we are trying to find TR. We also know that TS = 60. We can set up the proportion and solve for TR:

TR = (60/19) * 34
