Answer:
1) 37
2) 23
3) 4
4) 58
5) 67
6) 7
7) x = 14
BC = 27
CD = 61
BD = 88
Explanation:
1) Add them
2) Subtract them
3) Add them and set equal to 36
6x + 1 + x + 7 = 36
4) Add them and set equal to 9x - 39
47 + 3x + 10 = 9x - 39
Substitute x into 3x + 10 to find EF
5) Add them and set equal to 6x - 35
19 + 4x - 20 = 6x - 35
Substitute x into 6x - 35 to find UW
6) Add them and set equal to 7x-27
3x - 5 + x - 1 = 7x - 27
7) Add them. Solve for x and substitute.
4x - 29 + 5x - 9 = 7x - 10
