Carrie buys 4.16 pounds of apples for 5.20 how much does 1 pound cost

JulijaS [17]

4.16 / 5.20 = 1 / x.....4.16 lbs to $ 5.20 = 1 lb to $x
cross multiply because this is a proportion
(4.16)(x) = (5.20)(1)
4.16x = 5.20
x = 5.20 / 4.16
x = 1.25 per lb <==

Hello there!

Goryan [66]

$(x^2+3)^2 + 7x^2+21=-10$

We want to convert this equation in terms of m, where $m = x^2+3$

While solving this problem, I instantly noticed the $x^2+3$ in the first term of the equation. Replace that with m.

$m^2 + 7x^2+21=-10$

Simplifying the rest is not as obvious. Using the distributive property, we can change $[7x^2+21]$ to $[7(x^2+3)]$

Do you see the "m" in here? Look again if you don't.

Now we can simplify the equation to $m^2 + 7m=-10$ and this cannot be simplified further.

I'm always happy to help someone who appreciates the help! :D
