Given:
Bobby put 1/3 of his lawn mowing money into his savings
He uses the remaining 2/5 to buy a video game.
He has $12 left.
To find:
The amount did he have at first.
Solution:
Let x be the initial amount.
Bobby put 1/3 of his lawn mowing money into his savings. So, the remaining amount is
He uses the remaining 2/5 to buy a video game. Then the remaining amount is
It is given that the remaining amount is $12.
Divide both sides by 2.
Therefore, Bobby have $30 at first.
Option B
We can store a total of 360 songs in 60 megabytes of space.
<u>Solution:</u>
It is given to us that It takes 24 megabytes to store 144 songs on a music player. We have been asked to find out what is the greatest number of songs that 60 megabytes could store.
To solve this question we can use the unitary method.
We will first find out how many songs can be stored in 1 megabyte. This can be done as follows:
Therefore, we can store 6 songs in 1 megabyte.
So, in 60 megabyte we can store the following number of songs:
So, we can store a total of 360 songs in 60 megabytes.
Answer:
Vertically opposite angles

What else can measure
The question has missing options. So, I will give a general explanation.
Using the attached image as a point of reference.
Given that:
The value of b is calculated as:
Because b and are vertically opposite angles
<em>This gives:</em>
<em></em><em></em>
<em></em>
<em>So, one possible answer to the question is a vertically opposite angle</em>
