How to find common denominators

Ok, It's hard to explain so I'll use an example.
1/5 + 2/15
now you try to find a number that goes into both for this example it would be 3
3*5=15 and then that equals the 2/15
so you then multiply 3 by the numerator getting the fraction
3/15 + 2/15
with the answer of
5/15 which can be reduced to
1/3

Answer:

c = 160 - 3(45)

Step-by-step explanation:

if c = the number of characters left;

160 = maximum number of characters that can be used in a text

3*45 = number of characters in sentences already used. (There are 3 sentences of 45 characters.)

(# of char left) = (max # char) - (# char already used) so:

c = 160 - 3*(45)

c = 160 - 135

c = 25

The generic equation of the line is:

$H-H0 = m (T-T0)$

Where,

m: slope of the line

(T0, H0): ordered pair belonging to the line.

The slope of the line is:

$m =\frac{H2-H1}{T2-T1}$

Substituting values we have:

$m =\frac{15-17}{5-3}$

Rewriting:

$m =\frac{-2}{2}$

$m = -1$

Then, choosing an ordered pair we have:

$(T0, H0) :( 5, 15)$

Substituting values we have:

$H-15=-(T-5)$

Rewriting the equation:

$H-15=-T+5$

$H=-T+5+15$

$H=-T+20$

Then, for 8 hours we have:

$H=-8+20$

$H=12$

Answer:

a linear equation to model the relationship between height H of the candle, and T time is:

$H=-T+20$

the candle will be 12 inches after burning 8 hours
