Answer=18%

177/150=1.18

1.18=118%

118%-100%=18%

___________________________
another way to solve the equation...

  150     177
_____=_____
100%      x

Cross Multiply
150x=17700
divide both sides by 150
x=118%

118%-100%=18%

What is the solution to this equation?
Fantom [35]

Answer:

x=-17

Step-by-step explanation:

<em>Original</em><em> </em><em>Equation</em><em>;</em>

<em>x</em><em>+</em><em>1</em><em>2</em><em>=</em><em>-</em><em>5</em>

<em>The</em><em> </em><em>1</em><em>2</em><em> </em><em>will</em><em> </em><em>cross</em><em> </em><em>the</em><em> </em><em>equal</em><em> </em><em>sign </em><em>so</em><em> </em><em>it </em><em>will</em><em> </em><em>become</em><em> </em><em>-</em><em>1</em><em>2</em><em>. </em><em>So</em><em> </em><em>it's</em><em> </em><em>going </em><em>to</em><em> </em><em>be</em><em>;</em>

<em>x</em><em>=</em><em>-</em><em>5</em><em>-</em><em>1</em><em>2</em>

<em>There </em><em>are</em><em> </em><em>two negative </em><em>number</em><em> </em><em>so</em><em> </em><em>you </em><em>add</em><em> </em><em>them</em><em> </em><em>and</em><em> </em><em>when</em><em> </em><em>you </em><em>add</em><em> </em><em>them</em><em> </em><em>it</em><em> </em><em>would</em><em> </em><em>still</em><em> </em><em>be</em><em> </em><em>negative</em><em>.</em><em> </em><em>And</em><em> </em><em>you </em><em>would</em><em> </em><em>have </em><em>to</em><em> </em><em>add</em><em> </em><em>them </em><em>because </em><em>when</em><em> </em><em>there </em><em>are</em><em> </em><em>two</em><em> </em><em>negative</em><em> </em><em>numbers</em><em> </em><em>without </em><em>any</em><em> </em><em>other</em><em> </em><em>sign </em><em>you </em><em>will</em><em> </em><em>have </em><em>to </em><em>add</em><em> </em><em>so</em><em> </em><em>it's </em><em>going</em><em> </em><em>to </em><em>be</em><em>;</em>

<em>x</em><em>=</em><em>-</em><em>1</em><em>7</em>

<em>This </em><em>is </em><em>the </em><em>final</em><em> </em><em>answer</em><em>!</em><em>!</em><em>!</em>

Write an equation of the line that passes through (0 0) and (2 6)
fiasKO [112]

Answer:

y = 3x

Step-by-step explanation:

Slope equation:

y2 - y1

--------

x2 - x1

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

         6 - 0          6

m = ----------- =   ----- = 3

         2 - 0           2

Your slope is 3.

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

Equation:

y = mx + b

Plug in the slope and you get:

y = 3x + b

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

Now to find b, you can use either coordinate point. So I will show you both ways :)

<u>(0,0)</u>                                                                     <u>(2,6)</u>

0 = 3(0) + b                                                     6 = 3(2) + b

Multiply 0 and 3                                           Multiply 2 and 3

0 = 0 + b                                                         6 = 6 + b

Subtract 0 to 0                                            Subtract 6 from 6

0 = b                                                                    0 = b

There is no y-intercept

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

Your answer: y = 3x

Hope this helped :)

HELP PLEASEE!!! I just need help with the 2 boxes
Soloha48 [4]

Answer:

y= x - 300

y = -246 -- Her equivalent weight on earth

Step-by-step explanation:

Given

The attached table

Required

Fill in the gaps

(a) The equation

First, we calculate the slope (m)

m = \frac{y_2  - y_1}{x_2 - x_1}

From the table, we can say that:

(x_1,y_1) = (0,-300)

(x_2,y_2) = (300,0)

So, we have:

m = \frac{0  -(-300)}{300 - 0}

m = \frac{0 +300}{300}

m = \frac{300}{300}

m = 1

The equation is then calculated using:

y - y_1 = m(x - x_1)

This gives:

y - (-300) = 1(x - 0)

y +300 = 1(x)

y +300 = x

y= x - 300

(b) When x = 54

Substitute 54 for x in y= x - 300

y = 54 - 300

y = -246
