n a survey, one out of three people named blue as their favorite color. Two out of seven named red. If 1,092 people were included in the survey how many named neither blue nor red as their favorite color?
2. The triangles below are similar find the value of X
For number two There are two triangles and one is big the right side says 21 same with the left side and the bottom says 24 for the other triangle both left and right are 10.5 and its a small one and the bottom is X
1-(1/3+2/7) = 21/21 - (7/21+6/21).
21/21 - 13/21 = 8/21 of those surveyed
chose neither color.
8/21 * 1092 = 416 Named neither blue nor red.
