GCF stands for greatest common factor so if u have a problem like let's say, "What is the gcf of 36 and 90?" all u do is go down your multiples table and write them all down till 36 you will get 9 and if u take 10×9 it equals 90. For LCM all you do is go down your multiples table and find the least number that is the same with each other.

If the radius of mars is about 13.7% of neptune's radius, what is the radius of neptune?

Gnesinka [82]

You said that M is 13.7% of N

In algebraic notation M = 0.137 N

Divide each side by 0.137 : N = M / 0.137 = 7.3 M (rounded)

Online or in a real book, you can look up the radius of Mars.
Then write it in place of 'M' in this solution, and you'll have
an actual number for the radius of Neptune.

dem82 [27]

$\left \{ {{x=4y+6} \atop {x-3y=4}} \right. \\\\
4y+6-3y=4\\\\
y+6=4\ \ \ \ | subtract\ 6\\\\
y=-2\\\\
x=4y+6=4*(-2)+6=-8+6=-2$
