-1/2 is a rational number because it does not go on for infinity
:)))
Answer:
91 + 125 + 92 +(3x-5) + (4x- 8)= 540
308 +3x -5 +4x -8 =540
7x - 295 = 540
7x = 540 -295
7x = 245
x = 245/7
x = 35
Step-by-step explanation:
Answer: (assuming there are absolute value bars on the x + 8) x = -7, x = -9
Step-by-step explanation:
x + 8 = 1
subtract 8
x = -7
x + 8 = -1
subtract 8
x = -9
Answer is t_<10
-3t+9_>-21
-3t_>-30
t_<10
**when you divide or multiply both sides by a negative you have to flip the sign**
you can substitute numbers to make sure your answer is correct. For example if u substitute t=9 -27+9_>-21 -18_>-21 which is correct.(but you’ll see it’ll be incorrect if u put t=11)
