What is the sign of s^67/t^9 when s < 0 and t > 0?
Sphinxa [80]

Answer:

  • negative

Step-by-step explanation:

The sign of a product or quotient cannot be determined by the positive number (t), so we can ignore it. The sign of the expression will be negative if and only if there are an odd number of negative factors.

Here, there are 67 (an odd number) negative factors, so the expression will be negative.

An internet cafe charges a fixed amount per minute to use the internet. The cost of using the internet in dollars is, y = 3/4x.
Vinil7 [7]

ANSWER

8 minutes

EXPLANATION

We know that the cost of using the internet in dollars is given by,

y=\frac{3}{4}x

Where x is the number of minutes spent on the internet.

In this problem, we have to find how many minutes will 6 dollars buy. In other words, we have to find x for y = 6. To solve the given equation for x, we have to multiply both sides by 4,

\begin{gathered} 4y=4\cdot\frac{3}{4}x \\  \\ 4y=3x \end{gathered}

And divide both sides by 3,

\begin{gathered} \frac{4y}{3}=\frac{3x}{3} \\  \\ \frac{4y}{3}=x \end{gathered}

So, for y = 6, x is,

x=\frac{4\cdot6}{3}=\frac{24}{3}=8

Hence, $6 will buy 8 minutes.

How do I solve these? thanx in advance

7. Subtract 5.7 from both sides to get the variable on one side. (f=2)
8. Subtract 5.52 from both sides to get the variable on one side. (f=5)
9. Add 3.77 to both sides so the variable will be on one side. 
10. Add 10.58 to both sides.
11. Divide by 2.2 on both sides. 2.2b/2.2 will leave you with the variable b. 8.8/2.2=4; b=4.
12. Divide by 2.5b on both sides. 2.5b/2.5 leaves b. 10/2.5= 4; b=4.
