Jake went on a riverboat tour. After returning from the tour, he was curious to know the speed at which the boat was going. Duri
atroni [7]
I'm sorry I'm too lazy to read all of that. However, I did get the main point. The river was going at 3 mph. Since he wanted to travel 10 miles upstream and downstream, you would have to subtract 20 by 3. This would mean he was going at a speed of 17 mph.

Factor -3/4 out of 3/2x - 9/4y
Vikki [24]

Answer:

-\frac{3}{4} \times (-2x +3y)

Step-by-step explanation:

To factor out -3/4 out of that equation, multiply and divide by -3/4.

Say ;

=\frac{3}{2}x -\frac{9}{4}y

=(\frac{3}{2}x -\frac{9}{4}y) \times \frac{-\frac{3}{4} }{-\frac{3}{4}}

Now, rearranging and making necessary commutations.

=-\frac{3}{4} \times (\frac{3}{2}x -\frac{9}{4}y) \times \frac{1 }{-\frac{3}{4}}

=-\frac{3}{4} \times (-2x +3y)

Factoring -3/4 we get an equation without any fractions

= -2x + 3y

satela [25.4K]

Answer: She needed 144 square feet of carpet.

Step-by-step explanation:

Given : Maria is buying new carpet. Her bedroom is in the shape of a square.

The length of each side is 12 feet.

We know that the area of square = (side)^2

So , the area of the bedroom = (12)^2  [which is an exponential expression]

Simplify it

The area of the bedroom = 12\times12=144\ \text{ft}^2

Also, the carpet she needed = Area of the bedroom.

Thus , She needed 144 square feet of carpet.
