Answer:   x-6 < -15

=======================================================

Explanation:

"six subtracted from x" translates to "x-6"

So the word problem updates to "x-6 is less than -15"

Then we replace the "is less than" with "<" without quotes.

---------

Extra info: If you want to solve for x, then we add 6 to both sides like so

x-6 < -15

x-6+6 < -15+6

x+0 < -9

x < -9

So any number smaller than -9 will work in place of x.

Simplify this equation 8x-4+6x+15

Answers

Answer:

14x + 11

Step-by-step explanation:

Collect all the like terms together.

Positive 8x and positive 6x both have an x so after adding them together you get 14x. Negative 4 and positive 15 are also like terms so after adding them together you get positive 11.

The final answer being 14x + 11

Answer:

14x + 11

Step-by-step explanation:

8x - 4 + 6x + 15 =

8x + 6x + 15 - 414x + 15 - 414x + 11

simplify this equation is 14x + 11

Cups cost x dollars each. Mugs cost (x + 2) dollars each. (a) Write down an expression, in terms of x, for the total cost of 12 cups and 6 mugs. ............................................................................... dollars (2) (b) The total cost of 12 cups and 6 mugs is 57 dolllars.
work out the cost of 1 cup

Answers

Answer:

a. [tex]18x + 12[/tex]

b. $2.50

Step-by-step explanation:

a. If there are 12 cups and 6 mugs, and one cup is x and 1 mug is x+2, then multiply to get 18x + 12

b. Use the previous equation 18x+12=57 to get your answer. First move the 12 over to change the 57 to a 45. Then divide 45/18 to get 2.50 as you answer.

What is a quadratic equation?

It is a polynomial that is equal to zero. Polynomial of variable power 2, 1, and 0 terms are there. Any equation having one term in which the power of the variable is a maximum of 2 then it is called a quadratic equation.

The quadratic equation is given below.

102x + 11 = (x + 6)² – 2

Open square, we have

       102x + 11 = x² + 12x + 36 – 2

x² – 90x + 23 = 0

By the formula, we have  the value of x

[tex]x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}\\\\x = \dfrac{90 \pm \sqrt{(-90)^2}-4*1*23}{2*1}\\\\x = 89.74, 0.256[/tex]

The approximate soluton of the equation 102x + 11 = (x + 6)² – 2 is 0.6. Then the correct option is E.

What is the length of PR?
A. 7

C. 6
D. 9​

Answers

Answer:

C

Step-by-step explanation:

The triangles are similar by the AA postulate, thus the ratios of corresponding sides are equal, that is

[tex]\frac{AB}{PQ}[/tex] = [tex]\frac{AC}{PR}[/tex] , substitute values

[tex]\frac{20}{5}[/tex] = [tex]\frac{24}{PR}[/tex] ( cross- multiply )

20PR = 120 ( divide both sides by 20 )

PR = 6 → C

Make a number line and mark the points that represent the following values of x. 5x<12

Answers

Answer:

The answer is: x < 2.4

Step-by-step explanation:

5x < 12

If we divide both sides by 5, we get an equation like this:

x < 12/5

Then we can convert that fraction to a decimal and we get this!

x < 2.4

Finally, in order to draw it on the number line, we need to do this:

Find 2.4 on the number line, then draw an open circle on that 2.4. Then, attach an arrow going from that circle all the way to the left of the number line! The circle and arrow represents the fact that "x" is not equal to 2.4, but it is smaller. If it was equal to 2.4 or smaller, then the open dot would have to be a closed dot!!!!
