Answer:

If, a = 2 and b = 3

It's not equivalent.

<h3>Diego</h3><h3> $4a + 9b = 7a + 5b - 3a + 4b \\ 4(2) + 9(3) = 7(2) + 5(3) - 3(2) + 4(3) \\ 8 + 27 = 14 + 15 - 6 + 12 \\ 35 = 35 \\$ </h3>

It's equivalent.

The correct equation is 4a + 9b.

Any time Speedy the Sloth is not sleeping, she drinks chamomile tea at a steady rate of 2/7 of a cup per hour. Yesterday, she dr

Nitella [24]

<u><em>Answer:</em></u>

She stayed awake for 295 minutes today

<u><em>Explanation:</em></u>

<u>We are given that:</u>

Yesterday, she drank one cup

Today, she drank $\frac{17}{42}$ of a cup more than yesterday

<u>This means that:</u>

Number of cups she drank today = $1+\frac{17}{42}=1\frac{17}{42}cups$

Now, we know that she drinks $\frac{2}{7}$ of a cup per hour any time she is not sleeping

We use cross multiplication to get the time she took to drink $1\frac{17}{42}$ cups

1 hour ...........................> $\frac{2}{7}$ of a cup

?? hours ......................> $1\frac{17}{42}$ cups

Time taken = $\frac{1\frac{17}{42}*1 }{\frac{2}{7} } = \frac{59}{12} = 4\frac{11}{12} hours$

This means that she was awake for $4\frac{11}{12}$ hours

<u>Finally, we convert this to minutes:</u>

Knowing that 1 hour has 60 minutes, therefore:

She stayed awake for $4\frac{11}{12} * 60 = 295$ minutes

Hope this helps :)

the length of the rectangle is twice its width. write and solve a system of linear equations to find the length L and width W of

xz_007 [3.2K]

Answer:

2 ( m + 2 m) = 36 is the required linear equation

Length of the rectangle is 12 ft and width = 6 ft

Step-by-step explanation:

Let the width of the rectangle = m ft.

So, the length of the rectangle = 2m ft.

Perimeter of rectangle = 36 ft

Now, PERIMETER OF THE RECTANGLE = 2(LENGTH + WIDTH)

⇒2 ( m + 2m) = 36

or, 2 x 3m = 36

⇒ 6m = 36 , or m = 36/6

⇒ m =6 ft

So, the Width of the rectangle; = m = 6 ft

and the Length of the rectangle = 2 m = 2 x 6 = 12 ft.
