Answer:

4x+12y = 4 (x+3y)

35x+50y = 5 (7x+10y)

18x+9y = 9 (2x+y)

32x+8y = 8 (4x+y)

100x+700y = 100 (x+7y)

Step-by-step explanation:

You basically have to figure out what x and y are being divided by to get the x and y on the other side and put that before the parenthesis. For example in the first question in order to get x you must divide 4x by 4 and to get 3y you must divide 12y by 4 as well.

A race car travels 100 feet in 5 seconds, at this rate of speed, how many feet will the race car travel in a minute

Basile [38]

There are 60 seconds in one minute, and 60/5=12, so the race car would travel 100 feet every 5 seconds 12 times in one minute. You can simply multiply 100 by 12 to get your answer.
100x12=1200
The race car travels 1,200 feet in one minute.

Simplify completely 10x6y3+20x3y2/5x3y

Kryger [21]

Answer:

$\large\boxed{\dfrac{10x^6y^3+20x^3y^2}{5x^3y}=2x^3y^2+4y}$

Step-by-step explanation:

$\dfrac{10x^6y^3+20x^3y^2}{5x^3y}=\dfrac{(5x^3y)(2x^3y^2)+(5x^3y)(4y)}{5x^3y}\\\\=\dfrac{5x^3y(2x^3y^2+4y)}{5x^3y}\qquad\text{cancel}\ 5x^3y\\\\=2x^3y^2+4y$
