Translate five times the sum of a number and three into a mathematical expression
sergiy2304 [10]

Answer:

5(x-3)

Step-by-step explanation:

The word "SUM" means the answer to an "ADDITION".

"SUM" is always used with the word "AND" to indicate which numbers are being added.

The SUM of a number AND -3 is written as:  

( x + ( − 3 ) ), or  ( x -3 )

(where we have chosen the number to be  x .)

But we want FIVE of those sums; this means:

5  ( x − 3 )

What is the quotient of 2^4/2^-4
Tamiku [17]

When dividing a number by another with the same base, you can simply subtract the denominator's exponent from the numerator's.  That gives you

2⁴ ⁻ ⁽⁻⁴⁾ = 2⁽⁴ ⁺ ⁴⁾ = 2⁸
