Triple u then divide 3 by the result?
kkurt [141]

Answer:

beinggreat78~is~here~to~help!

The equation should look something like this.

\frac{u(3)}{3}

Be careful with your use between cubing and multiplying; Cubing is multiplying the number by itself multiple times, while multiplying is like repeated adding, yet much easier.

In this case, if it says triple, I highly recommend multiplying by 3, which is what I did, it only looks different because it is in parentheses.

What have we learned?

<h3>We learned how to write algebraic equations, and some further information on multiplying.</h3>

You have $20 gift card from a bookstore that you use to buy two books for $18.49. The sales tax is 5.75%. Will the gift card cov
Katena32 [7]
Hi!

18.49 * 5.75% = 1.063175

18.49 + 1.063175 = 19.553175 (Round to the nearest cent).

The cost (including tax) will be $19.55. Since $20 is greater than $19, the gift card will be able to cover the cost!

zhenek [66]
So the larger number is x, and the smaller number is y
7y=x
3x=7+4y

(So plug in the 7y=x information into the second equation)

3(7y)=7+4y
21y=7+4y
17y=7
y=7/17
