Nutka1998 [239]

T + k = 1655
k = t + 239

now we sub
t + t + 239 = 1655
2t + 239 = 1655
2t = 1655 - 239
2t = 1416
t = 1416/2
t = 708 ft <== terminal tower

k = t + 239
k = 708 + 239
k = 947 ft <=== key tower

Solve for x: -5 < 8x + 11 < 19

vladimir1956 [14]

Answer:

-2<x<1

Step-by-step explanation:

-5 < 8x + 11 < 19

Subtract 11 from all sides

-5-11 < 8x + 11-11 < 19-11

-16 < 8x<8

Divide by 8

-16/8 < 8x/8 <8/8

-2<x<1
