The points J, K, L and M all lie on the same line segment, in that order, such that the ratio of J K : K L : L M JK:KL:LM is equal to 2 : 1 : 2. 2:1:2. If J M = 30 , JM=30, find J L . JL.

If the measure of angle 1 is 110 degrees and the measure of angle 3 is (2 x+10 degree), what is the value of x?

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.
