A 16-inch board is to be cut into three pieces so that the second piece is twice as long as the first plece and the third piece is 5 times as long as the first piece. If x represents the length of the first piece, find the lengths of all three pieces.
What is the length of the first piece?

1. what is the formula for finding the vertical distance between two points on a coordinate plane?

An unknown number x is at most 10. which graph best represents all the values of x? number line graph with closed circle on 10 and shading to the right. number line graph with open circle on 10 and shading to the right. number line graph with open circle on 10 and shading to the left. number line graph with closed circle on 10 and shading to the left.

Will mark ! (10 points also! ) if x varies inversely with y and x =6 when y= 10, find y when x=8 a. y=4.8 b. y=7.5 c. y=40/3 d. y=4/15
