Represent the following sentence as an algebraic expression, where "a number" is the letter x. \text{1 is subtracted from a number.}
1 is subtracted from a number.

x-1

Step-by-step explanation:

it is x-1 because 1 is subtracted from a number and the number is x. when it says subtracted from you flip the equation and put the first number last and put a minus sign.

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
