Answer:

x>-10/7 or ≈ -1.4285714285714285714285714285714

Step-by-step explanation:

transfer the -7 coefficient over to the right

Hey there!

-7x > 10

DIVIDE -7 to BOTH SIDES

-7x/-7 > 10/-7
CANCEL out; -7/-7 because it give you 1

KEEP: 10/-7 because it give you the x value

NEW EQUATION: x = 10/-7

SIMPLIFY IT!

x = - 10/7 OR x = -1 3/7

⇡ EITHER OF THOSE SHOULD WORK BECAUSE THEY ARE EQUIVALENT TO EACH OTHER! ⇡

It is an OPEN circle shaded to the left starting between -1 & -2. (Little over -1)

Therefore, your answer is:

x = - 10/7 OR x = -1 3/7

Good luck on your assignment & enjoy your day!

Step-by-step explanation: The purpose of scientific notation is for scientists to write very large, or very small, numbers with ease.

Answer:

1.) Option C

2.) Option B

3.) Option D

4.) Option A

Step-by-step explanation:

[tex] \frac{3x {}^{2} }{y {}^{ - 3} } \\ [/tex]

Here, we know that

[tex]a {}^{ - 1} = \frac{1}{a} \\ [/tex]

So,

[tex] \frac{ {3x}^{2} }{y {}^{ - 3} } = \frac{ {3x}^{2} }{ \frac{1}{y {}^{ 3} } } = {3x}^{2} y { }^{3} \\ [/tex]

Thus, Option C is correct

[tex]( {4}^{0} )( {4}^{2} ) \\ [/tex]

We know that,

n⁰ = 1

where, n = any real number

So,

[tex]( {4}^{0} )(4 {}^{2} ) = 1 \times 16 = 16 \\ [/tex]

Thus, The answer is 16

[tex]( \frac{5}{3} ) {}^{ - 3} \\ [/tex]

We know that

[tex]a {}^{ - 1} = \frac{1}{a} \\ [/tex]

So,

[tex]( { \frac{5}{3} )}^{ - 3} = ( { \frac{3}{5} )}^{3} = \frac{27}{125} \\ [/tex]

Thus, Option D is correct

[tex] \frac{a {}^{2} {b}^{5}c {}^{0} }{ab {}^{7} } \\ [/tex]

[tex] \frac{a {}^{2} {b}^{5} c {}^{0} }{ab {}^{7} } = \frac{a}{ {b}^{2} } \\ [/tex]

Thus, Option A is correct

[RevyBreeze]

Answer:

side = 20 cm

Step-by-step explanation:

Since the triangle is equilateral then the 3 sides are congruent.

Equate the 2 given sides and solve for x

5(x - 3) = 2x + 6

5x - 15 = 2x + 6 ( subtract 2x from both sides )

3x - 15 = 6 ( add 15 to both sides )

3x = 21 ( divide both sides by 3 )

x = 7

then length of side is

2x + 6 = 2(7) + 6 = 14 + 6 = 20 cm

Answer:

20 cm

Step-by-step explanation:

Properties of an Equilateral Triangle

Given information

Find value of x

As side lengths are equal, equate the expressions and solve for x.

   2x + 6 = 5(x - 3)

⇒ 2x + 6 = 5x - 15

⇒ 2x + 6 + 15 = 5x - 15 + 15

⇒ 2x + 21 = 5x

⇒ 2x + 21 - 2x = 5x - 2x

⇒ 21 = 3x

⇒ 21 ÷ 3 = 3x ÷ 3

⇒ 7 = x

⇒ x = 7

Side lengths

Substitute x = 7 into one of the given expressions.

⇒ length of one side:  2(7) + 6 = 20 cm

Answer:

Time goes down to 16.47 min

Step-by-step explanation:

Formula

Time to melt = k / Temperature      (I doubt it is this simple)

Givens

Temp = 70

Time = 20

k  =

Solution

20 = k / 70             Multiply both sides by 70

20*70 = k

k = 1400

Problem

What happens when Temp = 85?

Time = k / Temp

Time = 1400 / 85

Time = 16.47 Min

Value of [tex]x[/tex]is [tex] - 12[/tex].

Final Answer is [tex]480[/tex]

Step-by-step explanation:

Assume that:

First number = x

Second number = 20 - x

Putting the given conditions,

[tex]2x^{2} + 3(20 - x)^{2} [/tex]

Putting the formula (a-b)²=(a²+2ab+b²) in (20-x)²,

[tex]2 {x}^{2} + 3(20^{2} - 2 \times 20 \times x + {x}^{2})[/tex]

[tex] = > 2 {x}^{2} + 3(400 - 40x + x^{2})[/tex]

Opening the brackets,

[tex]2 {x}^{2} + 3 \times 400 - 3 \times 40x + 3 \times {x}^{2} [/tex]

[tex] = > 2 {x}^{2} - 1200 - 120x + 3{x}^{2}[/tex]

[tex] = > (2x^{2} + 3 {x}^{2}) - 120x + 1200[/tex]

[tex] = > 5 {x}^{2} - 120x + 1200[/tex]

[tex]As \: x= - \frac{b}{2a}[/tex]

[tex] = > - \frac{120}{2 \times 5}[/tex]

[tex] = > - \frac{120}{10} [/tex]

[tex] = > - 12[/tex]

Now substituting the value of x in 5x²-120x+1200,

[tex] = > (5 \times {12}^{2} )-(120 \times 12)+1200[/tex]

[tex] = > (5 \times 144)-(1440)+1200[/tex]

[tex] = > 720 - 1440 + 1200[/tex]

[tex] = > 720 - (1440 - 1200)[/tex]

[tex] = > 720 - 240[/tex]

[tex] = > 480[/tex]

Answer:

A. [tex]5x^4 - 37x^3 - 6x^2 + 41x - 6[/tex]

step-by-step-explanation:

Answer:

[tex]5x^4- 37x^3-6x^2+ 41x-6[/tex]

Step-by-step explanation:

simplify the following expression:  

[tex](5x^4 - 9x^3 + 7x - 1) + (-8x^4 +4x^2-3x + 2) - (-4x^3 + 5x - 1)(2x -7)[/tex]

Expand [tex](-4x^3 + 5x - 1)(2x -7)[/tex]

[tex]\implies -8x^4 +28x^3+10x^2-35x-2x+7\\\\\implies -8x^4 +28x^3+10x^2-37x+7\\[/tex]

Therefore:

[tex](5x^4 - 9x^3 + 7x - 1) + (-8x^4 +4x^2- 3x + 2)-(-8x^4 +28x^3+10x^2-37x+7)[/tex]

Group and combine like terms:

[tex]5x^4 -8x^4- 9x^3 +4x^2+ 7x - 3x- 1 + 2-(-8x^4 +28x^3+10x^2-37x+7)\\\\\implies -3x^4- 9x^3 +4x^2+ 4x +1-(-8x^4 +28x^3+10x^2-37x+7)[/tex]

Apply the distributive rule:  [tex]-(-a+b)=a-b[/tex]

[tex]\implies -3x^4- 9x^3 +4x^2+ 4x +1+8x^4-28x^3-10x^2+37x-7[/tex]

Group and combine like terms:

[tex]\implies -3x^4+8x^4- 9x^3 -28x^3+4x^2-10x^2+ 4x+37x +1-7\\\\\implies 5x^4- 37x^3-6x^2+ 41x-6[/tex]

Answer:

D = 18

Step-by-step explanation:

Answer:

-123

Step-by-step explanation:

13(-x+4)-6 when .x is 13

we just replace x with 13

13(-13+4)-6

13(-9)-6

applying bodmas we multiply 13 by negative 9 before the subtraction aspect

13*-9=-117

-117-6=-123

Answer:

x=0

Step-by-step explanation:

x°+65°+109°+136°=310°

we know that this whole equation equals 310.

so we add all the numbers equaling x+174+136=310 : x+310=310

x clearly equals 0 and even then you can subtract 310 from both sides which still gives you 0.

hopefully this helps.

Heya!

Answer:

x° = 0°

Step-by-step explanation:

x°+ 65° + 109° + 136° = 310°

Add all of the degrees on the left side together.

x° + 310° = 310°

Subtract 310° from both sides.

x° + 310° = 310°

    - 310°   - 310°

+ 310° and - 310° cancel out. 310° - 310° is 0.

x° = 0°

So, x° = 310° is your answer.

Hope this helped! :D

Speed is the rate at which a body changes its position. The speed by which Marina runs is 4 miles/ hr.

Speed is the rate at which a body changes its position. It is given by the formula,

[tex]\rm{Speed = \dfrac{Distance}{Time}[/tex]

Given to us

Marina can bicycle 19. 5 miles at the same time it takes her to run 6 miles.

Marina bikes 9 miles per hour faster than she runs.

Let the speed of the Marina running be s, and the time is taken to run 6 miles be t.

Time is taken by Marina to cover a distance of 6 miles by running,

[tex]\rm t = \dfrac{6\ miles}{s}[/tex]

Since the speed of Marina's bicycle is 9 miles per hour faster than she runs. Time is taken by Marina to cover a distance of 19. 5 miles by bicycle,

[tex]\rm t = \dfrac{19.5\ miles}{s+9}[/tex]

We know that Marina can bicycle 19. 5 miles at the same time it takes her to run 6 miles. therefore,

[tex]\rm t = \dfrac{6\ miles}{s}= \dfrac{19.5\ miles}{s+9}[/tex]

[tex]\dfrac{6}{s}= \dfrac{19.5}{s+9}[/tex]

Solving the given equation we will get,

[tex]\rm s = 4\ miles/hr[/tex]

Hence, the speed by which Marina runs is 4 miles/ hr.

Answer:

The range is 8

Step-by-step explanation:

Recall that the range of a data set is the distance between the maximum and the minimum, therefore:

Range = Maximum - Minimum = 9 - 1 = 8

Answer:

Subtract the minimum data value from the maximum data value to find the data range. In this case, the data range is

9−1=8

Step-by-step explanation:

So therefore,the range is 8

Answer:

4 Cases

Step-by-step explanation:

If they bought 3 cases they would only have 864

Answer:

4 cases

Step-by-step explanation:

Find out how many pencils per case:

1 case = 24 boxes

1 box = 12 pencils

1 case = 24•12 = 288 pencils

Divide the amount of needed pencils (900) by how many per case there are (288) to find how many cases you need:

900÷288=3.125 (or 3 1/8)

Since you can't get a part of a case (for the 1/8 of a case you need), you will need to round up to 4 cases.

Step-by-step explanation:

You first need to isolate the variable, d. To do this, you move everything away from it, using the opposite order of operations for each variable. First, you need to subtract 2 on both sides which gives you 2d=2, then you divide 2 from 2d and divide it with the single 2 and get 1. Hope that helps :)
