Answer:

15x -45
3(5x -15)

Step-by-step explanation:

The expression can be fully factored as ...

3·5·(x-3)

Equivalent expressions can be formed by eliminating parentheses to give ...

15x -45

or by combining different pairs of factors:

3(5x -15)
5(3x -9)

Of course any of the terms can be broken apart and/or combined in different ways:

= 15(x -2) -15

= (7x -7) + 2(4x -19)

Answer:

$\frac{16}{36} = \frac{8}{18} = \frac{4}{9}$

Step-by-step explanation:

$\frac{16}{36} = \frac{16/4.5}{36/4.5} = \frac{3.5555}{8} \neq \frac{3}{8} \\\\\frac{16}{36} = \frac{16/12}{36/12} = \frac{1.3333}{3} \neq \frac{1}{3} \\\\\frac{16}{36} = \frac{16/9}{36/9} = \frac{1.7777}{4} \neq \frac{1}{4} \\\\\frac{16}{36} = \frac{16/4}{36/4} = \frac{4}{9} \\\\\frac{16}{36} = \frac{16/7.2}{36/7.2} = \frac{2,2222}{5} \neq \frac{2}{5} \\\\\frac{16}{36} = \frac{16/2}{36/2} = \frac{8}{18} \\\\$

chelsea takes the bus to school,but she walks home. the bus travels to the school at an average speed of 45 miles per hour. whil

jekas [21]

For this case, the first thing you should know is:
d: v * t
Where,
d: distance
v: speed
t: time
To go to school by bus we have:
d = 45 * t
To return from school we have:
d = 2.5 * (1-t)
how the distance is the same:45 * t = 2.5 * (1-t)
Answer:
the equation that will help find the time it takes chelsea to get to school on the bus is:
45 * t = 2.5 * (1-t)
Note: the equation will have one solution.
