Mathematics
1 answer:
vovikov84 [41]3 years ago
4 0
THE ANSWER IS 42,000.

TO GET THIS WE KNOW THAT 1 KILOMETERS IS 10,000. 

SO YOU TAKE 4.2 AND MULTIPLY IT BY 10,000. THAT EQUALS 42,000.

What is the value of 9(n+2)−5n for n=14?<br> 3<br> 9<br> 10<br> 19
Murrr4er [49]
If you want to know the value of a  function, you need to substitute the variable (here n) for the value:

so in the function

9(n+2)−5n

we substitute n with 14:

<span>9(14+2)−5*14

first calculate the inside of the bracket:

</span>
<span>9*16−5*14

9 times 16 is 144

144-5*14

5*14 is 70, so we have

144-70=74

so the answer should actually be 74!

Perhaps you mistyped the questions? can you check it again, please?

Mario and Luigi have friends. They want to purchase some extra controllers. Each controller costs $29.99.
jonny [76]
An algebraic expression is a phrase in mathematics that consists of numbers such as 1,2,3 and the like, variables which are represented with letters and operations like addition, multiplication, subtraction and division. It is usually used to represent a certain situation which would relate the variables involved. To write the algebraic expression for the problem statement above, we do as follows:

Let x = number of consoles to be bought
      y = number of games to be bought
      z = number of controllers to bebought
     C = total cost of all

The total cost would be equal to the sum of the price multiplied by the number of consoles, games and controllers bought. We write the algebraic expression as follows,

C = 299x + 59.99y + 29.99z
