Answer:
-3
Step-by-step explanation:
-12(x-12)=-9(1+7x)
-12x+144=-9-63x
-12x+63x=-9-144
51x=-153
x=-153/51=-3
Answer:
13 cms
Step-by-step explanation:
By Pythagoras:-
x^2 = 12^2 + 5^2
x^2 = 144 + 25
x^2 = 169
x = √169
= 13
Answer:
Approximately 55ft
Step-by-step explanation:
Answer:
8 chickens
Step-by-step explanation:
Firstly, we need to know the number of eggs produced by a single chicken in 24 hours.
Since 2 chickens produce 6 eggs in 24hours, this means 1 chicken will produce 3 eggs in 24 hours.
Now, we need 24 eggs to be produced. Since the time is the same 24hours, meaning time is constant, the number of chickens required to produce 24 eggs will be 24/3 = 8 chickens
Hence, we can say that 8 chickens will produce 24eggs in 24 hours
Well, you can only combine the numbers with the variable (the x) in front of them, since there’s no other number on the left side of the equation to combine that lone number with
(example: 3x+2+5x; you can only add 3x and 5x together since 2 has no x).
So 3x and -2/9x would be your answer.
