Consider the numbers in the fraction: 
<span>6 is 2 times 3 </span>
<span>The denominator 15 is 5 times 3 </span>
<span>Numerator : Denominator = 6 : 15 or 2 : 5 </span>
<span>If the Denominator is to be 20 it is 4 times 5, </span>
<span>the Numerator has to be 4 times 2 </span>
<span>Answer: </span>
<span>6/15 = 8/20</span>

How to solve this linear equation step by step please
mote1985 [20]
\bf \cfrac{3}{c^2-4c}-\cfrac{9}{2c^2+3c}=\cfrac{2}{2c^2-5c-12}\\\\\\ &#10;\begin{cases}&#10;c^2-4c=&c(c-4)\\&#10;2c^2+3c=&c(2c+3)\\\\&#10;2c^2-5c-12=&#10;&(2c+3)(c-4)&#10;\end{cases}\\\\&#10;-------------------------------\\\\&#10;\textit{therefore, our LCD for the \underline{left-side} will have to be }\underline{c(c-4)(2c+3)}\\\\&#10;-------------------------------\\\\

\bf \cfrac{3}{c(c-4)}-\cfrac{9}{c(2c+3)}=\cfrac{2}{(2c+3)(c-4)}&#10;\\\\\\&#10;\cfrac{3(2c+3)-9(c-4)}{c(c-4)(2c+3)}=\cfrac{2}{(2c+3)(c-4)}&#10;\\\\\\&#10;\cfrac{6c+9-(9c-36)}{c(c-4)(2c+3)}=\cfrac{2}{(2c+3)(c-4)}&#10;\\\\\\&#10;\cfrac{6c+9-9c+36}{1}=\cfrac{2[c(c-4)(2c+3)]}{(2c+3)(c-4)}&#10;\\\\\\&#10;-3c+45=2c\implies 45=5c\implies \cfrac{45}{5}=c\implies 9=c

7(n - 7) = 3(2n + 3)
bija089 [108]

Answer: n=58

Step-by-step explanation:

7(n-7)=3(2n+3)

We move all terms to the left:

7(n-7)-(3(2n+3))=0

We multiply parentheses

7n-(3(2n+3))-49=0

We calculate terms in parentheses: -(3(2n+3)), so:

3(2n+3)

We multiply parentheses

6n+9

Back to the equation:

-(6n+9)

We get rid of parentheses

7n-6n-9-49=0

We add all the numbers together, and all the variables

n-58=0

We move all terms containing n to the left, all other terms to the right

n=58

What is the range of y=-3x+1 for the domain of {2, 8}
Zielflug [23.3K]

Answer:

[0,∞), {y|y≥0}

Step-by-step expl

The graph of y =|3x + 1| is attached.

By observation, we can see that the the least y-value that the graph can take is y =0 (i.e the x-axis) and the greatest y-value that the graph can take is positive infinity.

Hence the range is [0,∞), {y|y≥0}
