Preston is making cookies. he has 4 over 5 cup of flour in a bag. he then used two 1 over 10 cups of flour for his recipe. which of the following best explains the amount of flour left in the bag?

6 over 10, because 4 over 5 minus 2 times 1 over 10 equals 4 over 5 minus 3 over 10
5 over 10, because 4 over 5 minus 2 times 1 over 10 equals 4 over 5 minus 3 over 10
6 over 10, because 4 over 5 minus 2 times 1 over 10 equals 4 over 5 minus 2 over 10
5 over 10, because 4 over 5 minus 2 times 1 over 10 equals 4 over 5 minus 2 over 10

Match the following terms with their definitions. 1. bisector of a segment ray ba and ray bc are opposite rays if a, b, and c are collinear and b (the endpoint of both rays) is between a and c. 2. opposite rays a ray, , is the set of points beginning at point a and going infinitely in the direction of point b. 3. collinear points a line or segment that intersects the segment at its midpoint. 4. betweenness of points a set of two or more points all on the same line. 5. ray the distance between the endpoints of a segment. 6. space point b is between a and c if a, b, and c are collinear and the equation ab + bc = ac is true, where ab, bc, and ac are the distances between points a and b, b and c, and a and c, respectively. 7. midpoint of a segment a set of two or more points all on the same plane. 8. coplanar points the point on a segment that divides the segment into two equal segments. 9. length of a segment the set of all possible points. 10. line segment the set of two different endpoints and all points between them.

A. 127 cm^2 b. 144.5 cm^2 c. 172 cm^2 d. 50 cm^2

The linear combination method is applied to a system of equations as shown. 4(.25x + .5y = 3.75) → x + 2y = 15 (4x – 8y = 12) → x – 2y = 3 2x = 18 what is the solution of the system of equations? (1,2) (3,9) (5,5) (9,3)
