Answer:

Step-by-step explanation:

143.17

round the bill to the nearest $ 10..

that would make it $ 140

a 10% tip......its the same thing as multiplying by 0.1

and when u multiply any number by 0.1 ur actually starting at the decimal ( or the end of the number) and move one space to the left.

examples :

10% of 245 = 24.5

10% of 5010 = 501

10% of 76 = 7.6

10% of 88.5 = 8.85 .....if there is a decimal, start at the decimal

so.....10% of 140

start at the end of the number and move 1 space to the left...

ur answer is 14 <==

$14. Round $143.17 to $140. Multiply $140 by 0.1

Step-by-step explanation:

√9x2√18y2. √9=3. √x2=x. √18=√9×2=3√2. √y2=y. Therefore √9x2√18y2=3x3√2y = x√2y.

Solve the following equation. Remember to check for extraneous solutions 1/(x-6) + (x/(x-2)) = (4/(x²-8x+12)).

Answer:

-1, 2, 6

Step-by-step explanation:

We have to solve the equation as follows: 1/(x-6) + (x/(x-2)) = (4/(x²-8x+12)).

Now, we have, $\frac{1}{x-6} +\frac{x}{x-2} = \frac{4}{x^{2}-8x+12 }$

⇒ $\frac{(x-2)+x(x-6)}{(x-2)(x-6)} = \frac{4}{x^{2}-8x+12 }$

⇒ $\frac{x-2+x^{2}-6x }{(x-2)(x-6)} =\frac{4}{(x-2)(x-6)}$

⇒ $\frac{(x-2)(x-6)}{x^{2}-5x-2 }=\frac{(x-2)(x-6)}{4}$

⇒ $(x-2)(x-6)[\frac{1}{x^{2} -5x-2} -\frac{1}{4} ]=0$

⇒ $(x-2)(x-6) =0$ or, $[\frac{1}{x^{2} -5x-2} -\frac{1}{4} ]=0$

If, (x-2)(x-6) =0, then x=2 or x=6

If, $[\frac{1}{x^{2} -5x-2} -\frac{1}{4} ]=0$ , then $x^{2} -5x-2=4$

and (x-6)(x+1) =0

Therefore, x=6 or -1

So the solutions for x are -1, 2 6. (Answer)

BRAINLIEST WILL I GIVE HURRY

stepladder [879]

Answer:

{10,8}

Step-by-step explanation:

-3x + 4y = -62

4x + 5y = 0

let's eliminate the x

-3x + 4y = -62 | x -4 |

4x + 5y = 0 | x 3 |

12x - 16y = 248

12x + 15y = 0

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

-31y = 248

y = 248/(-31) = 8

since you must do this proble with elimination, we cant use subtitution. so we repeat the way once more to find x (eliminate y)

-3x + 4y = -62 | x 5 |

4x + 5y = 0 | x 4 |

-15x + 20y = -310

16x + 20y = 0

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

-31x = -310

x = -310/-31 = 10
