Answer:
t > -7
Step-by-step explanation:
8t - 2 - 9t < 5
Combine like terms
- 2 - t < 5
Add 2 to each side
-2-t+2 < 5+2
-t <7
Multiply each side by -1, remembering to flip the inequality
t > -7
Answer:
the answer would be 26
Step-by-step explanation:
To find the range you would have to subtract the biggest number in the sequence by the smallest number
Steps:
let “x” be number of hrs
let “y” be total cost
Abe:
50x + 75 = y
Plumbing Service:
65x=y
Since both equations are equal to y, you can set them equal to each other.
65x = 50x + 75
isolate for x:
65x - 50x = 75
15x = 75
x = 5
therefore it will take 5 hours for each to cost the same. you should call Abe for any task more than 5 hours because it will be cheaper and you should call the Plumbing Service for any task less than 5 hours because it will be cheaper.
Answer:
Step-by-step explanation:
CosB = ((15^2) + (8^2) - (14^2)) / (-2(15)(8))
cosB = 93 / -240
Take inverse cosine:
