Name the property of real numbers illustrated by an equation. π*3=3*π

It is the commutative property of multiplication. Put in simple language if you are multiplying 2 real numbers together, it does not matter which one you put into your calculator first: both ways will give you the same answer.

5 * 3 = 15

3 * 5 = 15

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
