Step-by-step explanation:
by considering how many inches (") are in one foot (').
the answer is 12. there are 12 in in every ft.
so, now we can convert everything to the smallest scale (inches) and do the calculation based on inches :
(8×12 + 4) - (2×12 + 6) = 96 + 4 - 24 - 6 = 100 - 30 = 70"
and now to translate 70" back into ft and in :
70/12 = 5 with a remainder of 10
70" = 5' 10"
The solution is 2x-7 is 78
The first question = 3p
The second question =
4x-3y+10z
56 + 41 + x = 180
97 + x = 180
x = 180 - 97
x = 83 <==
Answer:
A function normally tells you what y is if you know what x is.
