Answer:

x = 1.125 AKA x = 1 1/8 AKA x = 9/8

Step-by-step explanation:

CB to ED = 1 : 9

Scale Factor = 1/9

\frac{1}{9} = \frac{x}{x+9} -> cross multiply

9x = x + 9

-x     -x

8x = 9

\frac{8x}{8} =\frac{9}{8}

x = 9/8

Consider the function represented by the equation 6c = 2p – 10. Write the equation in function notation, where c is the independ
zhuklara [117]

we have

6c = 2p - 10

If c is the independent variable

then

p is the dependent variable

so

clear variable p

6c = 2p - 10

Divide by 2 both sides

3c = p - 5

Adds 5 both sides

3c+5 = p - 5 +5

p=3c+5

Write the equation in function notation

f(c)=3c+5

therefore

the answer is

the equation in function notation is equal to f(c)=3c+5

timurjin [86]

Answer:

25%- 1875 Votes

<em>7500 x 0.55 = 4125  (</em><em>first candite valid votes</em><em>)</em>

<em>7500 x 0.20 = 1500 (</em><em>invalid</em><em>)</em>

<em>first candite valid votes</em><em> </em><em>(</em><em>55</em><em>) + invalid votes (</em><em>20</em><em>) = 75% of total votes </em>

<em>first candite valid votes</em><em> </em><em>(</em><em>4125</em><em>) + invalid votes (</em><em>1500 </em><em>) = 5625 of total votes </em>

<em />

<em>100 (</em><em>total</em><em> </em><em>percent of votes</em><em>) - 75 (</em><em>total percent of votes</em><em>) = 25% Votes Left</em>

<em>7500 (</em><em>total</em><em> </em><em>number of votes</em><em>) - 5625 (</em><em>total number of votes</em><em>) = 1875 Votes Left</em>

<em>7500 x 0.25 = 1875 (</em><em>valid votes for the other candite</em><em>)</em>

Equation 2 : 7R+3G=9

Multiply Equation by 3, it becomes

3R+3G=60 ...... Equation 3

Now Equation 3 minus Equation 2

-4R = 51

R = - 51/4

Sub R into Equation 1, you can find G
