Question

Could somebody help me please? **ANSWER WILL RECIEVE METAL*
Solve each compound inequality:
42. -2 < or equal to d + 1/2 < 4 1/2
44. 2t < or equal to -4 or 7t > or equal to 49
46. -1 < or equal to 9 - 3 < 2

Answer 1

-2 <= d + 1/2 < 4 1/2 -- change mixed fraction to improper
-2 <= d + 1/2 < 9/2 -- subtract 1/2
-2 - 1/2 <= d + 1/2 - 1/2 < 9/2 - 1/2
-4/2 - 1/2 <= d < 8/2
-5/2 <= d < 4
===================
2t <= -4 -- divide by 2
t <= -2

7t >= 49 -- divide by 7
t >= 7

solution : t >= 7 or t <= -2
==================
-1 <= 9 - 3 < 2 .....Is there supposed to be a variable in here ??

Answer 2

thats suppose to be, -1 <= a - 3 < 2

Answer 3

-1 <= a - 3 < 2 -- add 3
-1 + 3 <= a - 3 + 3 < 2 + 3
2 <= a < 5

Answer 4

2 <= a < 5 is the solution?

Answer 5

yes..or a >= 2 and a < 5

Answer 6

Ohkay (: thank you !

Answer 7

anytime :)
