Answer:
Step-by-step explanation:
Put the value where the variable is and do the arithmetic. It can save some steps to simplify the expression first.
35 -c³ +8 = 43 -c³
<u>c = 1</u>
43 - 1³ = 43 -1 = 42
<u>c = 2</u>
43 - 2³ = 43 -8 = 35
<u>c = 3</u>
43 -3³ = 43 -27 = 16
The values that go in the blanks are 42, 35, 16.

<em>Additional comment</em>
It does not take long to learn how to use a spreadsheet for evaluating the same formula with a number of different values of the variable(s). Graphing calculators can do this, too. It is always appropriate to use the right tool for the job.
Familiarity with multiplication and addition facts is a very good place to start. It is also useful to memorize the squares and cubes of small integers. The latter are needed here.
Answer: find the answer in the explanation
Step-by-step explanation:
Two times a number, n that is, 2n
and four less than three times the same number, that is, 3n - 4
Cole is wrong for not interpreting the two statement differently into two separate expression.
Finding the sum of the two expression will be
2n + 3n - 4 = 5n - 4
So, if n = 2
Substitute 2 for n in the expression 5n -4
5(2) - 4
10 - 4 = 6

Answer:
4/8 and 4/10
Step-by-step explanation:
Required
Select which option is equivalent to 1/2 and 2/5
Option (a): 5/10 and 4/8
Simplify 5/10
Simplify 4/8
This is not true
Option (b): 1/3 and 4/12
1/3 is not equivalent to 1/2 or 2/5.
So, this is not true
Option (c): 4/12 and 5/10
Simplify 4/12
1/3 is not equivalent to 1/2 or 2/5.
So, this is not true
Option (d): 4/8 and 4/10
Simplify 4/8
Simplify 4/10
Hence, (d) is true
