I think what your asking for is that x=10
6m+30 is the answer.
Multiply 6 and m and you get 6m.
Multiply 6 and 6 and you get 30.
6m+30
X = 59, y = 44
2x + 18 + x - 15 = 180
3x + 3 = 180
3x = 177
x = 59
x - 15 = y
59 - 15 = y
44 = y
Divide both sides with -6 to then get 16=8-k. Then subtract 8 to both sides. to get 8=-k. Finally, divide both sides by -1 to get your answer, -8=k.
3 minutes = 2850
5 minutes = 4750
In 8 minutes he descended = 7600
1 min = 7600/8 = 950ft per min
Hope i become the brainliest answer.
