The Alden Middle School girls' soccer team won 80% of its games this season. If the team won 12 games, how many games did it play?

15 games

Step-by-step explanation:

a proportion helps!

12 80

x 100

Then use cross products:

12×100=1200

1200÷80= 15 games

I hope this helps!

you already gave the answer

step-by-step explanation:

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.
