Miranda learned that a used camera costs about half as much as a new one. she bought a used camera for $90. which equation could be used to find p, the price of miranda's camera if she had bought it new? p– 1/2 = 90 p= 1/2 × 90 2p = 90 p/2 = 90

Scale factor of 2 is used to enlarge a figure as shown below the area of is 18 in.²

Agroup of students want to create a garden. they do not know the exact measurements but they propose using a variable to represent the length and width of the garden. the length of the garden is 10 feet longer than double the width. use a single variable to write algebraic expressions for both the length and width of the garden. write an algebraic expression for the area of the garden. use mathematical terms to describe this expression.

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?
