Answer:

X< -4

Step-by-step explanation:

15 - 3x < 5x -17

15 - 17 < - 3x - 5x

-2 < 8x

X= - 4

1. a)

          2x    +     (-3)

   _______________

x  |      2x²    |    -3x      |

+  _______________

1  |       2x     |     -3       |

   -----------------------------

(2x - 3) (x + 1) = 2x² - 3x + 2x - 3 = 2x² - x - 3

b)

      x     +     2

   ____________

x  |   x²      |    2x    |

    ____________

3  |   3x     |      6    |

   -----------------------

(x + 2) (x + 3) = x² + 2x + 3x + 6 = x² + 5x + 6

Answer:

10. X = 2.75

11. X = 1.61

Hey there, I have the steps listed below but what is the problem asking, I cannot solve it unless it explains the problem. Thank you!

Step-by-step explanation:

10. 5x + 10 + 11x + 2 = 56

16x + 12 = 56

16/16x = 44/16

X = 2.75

11. -1 + 8x + 18x + 5 = 46

26x + 4 = 46

26/26x = 42/26

X = 1.61

Problem 10

-----------------------

Explanation:

The remote interior angles UTS and TSU add to the exterior angle AUT. This is because of the remote interior angle theorem. The interior angles you add cannot be adjacent to the exterior angle.

(angle UTS) + (angle TSU) = angle AUT

(5x+10) + (58) = 11x+2

5x+10+58 = 11x+2

5x+68 = 11x+2

68-2 = 11x-5x

66 = 6x

6x = 66

x = 66/6

x = 11

Use this x value to find that...

angle UTS = 5x+10 = 5*11+10 = 65

angle AUT = 11x+2 = 11*11+2 = 123

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

Problem 11

-----------------------

Explanation:

We'll use the same theorem as before

(angle BCD) + (angle CDB) = angle WBC

(46) + (-1+8x) = 18x+5

46-1+8x = 18x+5

8x+45 = 18x+5

45-5 = 18x-8

40 = 10x

10x = 40

x = 40/10

x = 4

angle CDB = -1+8x = -1+8*4 = 31

angle WBC = 18x+5 = 18*4+5 = 77

Answer:

n=9

Step-by-step explanation:

You use reverse PEMDAS.

First you would divide by 3 on both sides. This should give you:

n²=81

Then you would find [tex]\sqrt{81}[/tex]. Which is 9.

Answer:

141.74 grams

Step-by-step explanation:

According to the given situation, the computation of each baseball weighs is shown below:-

Each baseball weighs = Total weight of all ten baseballs ÷ Total amount

= 1,417.4 ÷ 10

= 141.74 grams

Therefore for determining the each baseball weighs we simply applied the above formula.

Answer:

television/ video games= 1/4

Step-by-step explanation:

cuz there are 2 sets of 30 min in an hour, make the video games time 4 sets of 30 min, and the tv time 1 set. so , the ratio would be 1/4.

The ratio of the amount of time spent on watching television to the amount of time spent on playing video games as a fraction in the simplest form is 1 : 4.

Ratio basically compares quantities, that means it shows the value of one quantity with respect to the other quantity.

If a and b are two values, their ratio will be a:b,

Given that,

Time spend on watching television = 30 minutes.

And time spend on playing video games = 2 hours.

To find the ratio of the amount of time spent on watching television to the amount of time spent on playing video games,

Use ration property,

Ratio = time spend on watching television/ time spend on playing video games

         = 30 minutes / 2 hours

         = 30 minutes / 2 x 60 minutes

         = 1 / 4

Ratio = 1 : 4

The required ratio of time spend on television to time spend on playing video games is 1 : 4.

Answer:

The X and Y intercepts to the equation -3x - 7y = 84 is

x-intercept (s): (−28,0)

y-intercept (s): (0,−12)

Step-by-step explanation:

To find the x-intercept(s), substitute in 0 for y and solve for x

−3x−7⋅0=84

Solve the equation.

x=−28

Answer:

Step-by-step explanation:

We are expected to convert from miles to kilometer

first day 85 miles =136.794km

Second day 125 mile=201.168km

third day 176 miles =283.245km

Total distance covered is

136.794km+201.168km+283.245km=621.207km

Therefore the total distance in kilometer is 621.207km

additive inverse. and additive inverse of a number “a” is the number that, when added to “a”, yields 0. this number is also known as the opposite (number), sign change, and negation. For a real number, it reverses its sign: the opposite to a positive number is negative, and the opposite to a negative number is positive.

Answer:

12 4/25 is equivalent to 12.16 .

In this triangle it is clear that the unknown side x is the hypotenuse of both the triangles that are being formed . So , let us take any one of the triangles and with it's length let us find the length of their hypotenuse which is side x .

= 5² + 5² = x² ( according to the pythagorean theorem the square on the hypotenuse will be equal to the sum of the squares on the other two legs )

= 25 + 25 = x²

= 50 = x²

= 7.0710678119 = x

But they have given that we have to round it off to the nearest tenths , so ;

= 7.0710678119 will be equal to = 7.10

= 7.1 = x

Therefore , the length of the unknown side x = 7.1 .

Answer:

6^10

Step-by-step explanation:

6^0 is essentially just 1. So 6^10 x 1 is 6^10.

Answer:

6^10

Step-by-step explanation:

When multiplying exponents with the same base number, you simply add the exponents and keep the bases the same

a^m * a^n = a^m+n

6^10 * 6^0 = 6^10+0

You can also look at it this way:

Any non-zero number to the power of 0 will ALWAYS equal 1

a^0=1

6^10 * 6^0 = 6^10 * 1 = 6^10
