We can use the distributive property to set up an expression that is equal to this problem.
14 times 8 is 112
14 times -6 is -84x
14 times 12 is 168
(If you don't know the distributive property ask and I can explain it)
We can combine that together to get:
112 +168 -84x
Or, condense it further:
280-84x is equivalent to 14(8-6x+12)
3x-6≤9
3x≤15
x≤5
so the answer is x≤5
23 Pennie’s is the answer I believe
Where 1/4 represents Bob and 1/6 represents Ted...
1/4x + 1/6x = 1
Multiply the two so there is no fraction by the GCF of 12.
3x + 2x = 12
Add 3x and 2x.
5x = 12
Divide by 5.
x = 12
Plug this value in.
With that, the answer is 2 hours and 24 minutes with x = 12 meaning 144 minutes.
