Complete the statement If x/7 = 5/3, then x+7/7 =?
lawyer [7]
Lets get started :)

\frac{x}{7} = \frac{5}{3}
We can cross multiply, to find the value of x
3x = 7 x 5
3x = 35
We have to divide by 3 on either sides to isolate x
\frac{3x}{3} =  \frac{35}{3}
3 and 3 cancels out

x = \frac{35}{3}

Then, x + \frac{7}{7}  ( 7 divided by 7 is 1)
\frac{35}{3} + 1   = \frac{38}{3}

sveticcg [70]

Answer:

540 megabytes

Step-by-step explanation:

We will first need to find out how much space a<em> singular song</em> will take up. We will do this by <em>the storage taken up (884) by the number of songs she has:</em>

884 / 221 = 4 mb taken up per song

Then we want to find out how many megabytes <em>135 of these songs take up</em>, so we will multiply the <em>mb taken up per song (4) by the number of songs we want to find (135)</em>:

4 x 135 = <em>540 megabytes</em>

<em />

<em>Edit: made a mistake in my original answer, apologies!</em>

Iteru [2.4K]

Answer:

12.5 kilograms

Step-by-step explanation:

Given:

Half of the granola served with breakfast.

Let the amount of Granola present initially = x kg

Half of it (\frac{x}{2}) served with breakfast, so remaining granola :

x-\dfrac{x}{2} = \dfrac{x}{2}

After dinner, the remaining granola 6,250 gm granola was served with yogurt dessert.

First of all, let us convert it to kilogram because the answer is required in Kilograms.

We know that:

1000 gms = 1 kilograms

1 gms = 0.001 kilograms

6250 gms  = 6250 \times 0.001 = 6.250 kilograms

Now, as per given question statement:

\dfrac{x}{2} = 6.250\ kg\\\Rightarrow x = 2 \times 6.250\\\Rightarrow \bold{x = 12.5\ kg}

So, the answer is:

Girl scout camp started with 12.5 Kilograms of granola.
