Answer(s):
Solution:
<u>We know that:</u>
- Brookie = x dollars
- Benji = x + (20% × x)
<u>Solution:</u>
To see which expression has been used, we will need to simplify the expression.
- Benji = x + (20% × x)
- => Benji = x + (20/100 × x)
- => Benji = x + (2/10 × x)
- => Benji = x + (0.2 × x)
- => Benji = x + (0.2x)
- => Benji = x + 0.2x
- => Benji = 1.2x
Looking at the options, Option A and Option B matches with our result.
Option A and B are correct.

Simon fills a container with 38 1-in, cubes. The container is a box of dimension 4 in. by 3 in. by 4 in.,How many more 1 in cubes does the container need to be completely filled?
Answer:
10 1-in cubes
Step-by-step explanation:
First, we determine the Volume of the box.
Volume of a Rectangular Prism =Length X Height X Width
Volume of the box = 4 X 3 X 4= 48 cubic inches
To fill the box container, we would need 48 1 in cubes.
Since Simon already filled the container with 38 1-in, cubes.
Number of 1-in. cubes required to fill the box
=48 -38
=10.
Simon would need 10 1-in cubes to fill the box.
We know that Frank is 1/4 Dana's age, so if Frank is represented by f, and Dana is represented by d, then the equation would be
1/4d = f
<span>Secondly, we know that Neil's age is one-half the difference between Dana's and Frank's ages. Because of we learned that Frank is a fraction of Dana's age, we can infer that he is younger than Dana. So, if Neil's age is represented by the variable n, then the equation would be
1/2(d - f) = n
Finally, if we know that Dana is 16 years old, we can find out the other siblings ages using the equations we made above.
d=16
1/4d = f
1/4(16) = f
4 =f
</span>1/2(d - <span>f) = n
</span>1/2(16-4) = n
1/2(12) = n
6=n
Therefore, Frank is 4 years old and Neil is 6 years old.
Answer:
-360
Step-by-step explanation:
1. Add 9 + 21 and subtract 9 - 21
2. That would be (30)(-12)
3. Then multiply 30 x -12
4. You get -360
I would say it’s 1yd, it’s too small to be 2yds.
