Answer:
1) 25
2) 155
3) 25
4) 25
5) 19
6)
7)
CODE:
Step-by-step explanation:
1) 180 - 155 = 25
2) 155 = angle 4
3) angle 1 and 5 are equal = 25
4) angle 1 and 7 are equal = 25
5) 19
5x + 15 = 8x - 42
5x + 15 - 5x = 15
8x - 42 - 5x = 3x - 42
15 + 42 = 57
3x - 42 + 42 = 3x
57 = 3x
57 / 3 = 19
3x / 3 = x
19 = x

25 + 155 + 25 + 25 + 19
recall d = rt, distance = rate * time.
let's say airplane A is going at a rate of "r", therefore airplane B is moving faster, at a rate of "r + 80".
now, after 3 hours, both planes have been travelling for 3 hours each, and say if A has covered "d" miles, then B has covered the slack of 2490 - d.
Answer: 1
Step-by-step explanation:
If you plug in 0 for x, 2 * 0 is 0 so it cancels out and you're left over with y = 1
