A student expressed the sum of 2 whole numbers as 5 times (8+3).What are the 2 whole numbers?
Marta_Voda [28]

Well if the two numbers are equal to 5x(8+3).

Lets say that these two numbers are X and Y,

So that would be X + Y = 5(8+3)

which means X + Y = 55

You could write that as a fuctions Y = 55 - X

Now by using the graph you get and the X values of [0,55] ( This means every value from 0 to 55 ), you will get a X and Y value that if you added up together will give you the value of 8(5+33)

An examples for the answers would be

(0,55) (1,54) (2,53) (3,52) (4,51) (5,50) (6,49) ... it goes on until x reaches 55.

Evaluate 3^2 + (5-2) X 4 - 6/3
muminat

Answer:

The result is 19

Step-by-step explanation:

3^{2}  + (5-2)x4 - 6/3

Step 1: Parenthesizing (5-2)=3

3^{2}  + 3x4 - 6/3

Step 2: Exponentiation 3^{2}=9

9  + 3x4 - 6/3

Step 3: Multiplication and division 3x4=12 and 6/3=2

9  + 12 - 2

Step 4: Addition and subtraction 9+12=21, and 21-2=19

21-2

19

The operations are ordered from highest to lowest in the order:

1. Parenthesizing,

2. Factorial,

3. Exponentiation,

4. Multiplication and division,

5. Addition and subtraction.

Hope this helps!
