We need to get rid of expression parentheses.
If there is a negative sign in front of it,
each term within the expression changes sign.
Otherwise, the expression remains unchanged.
Numerical 'like' terms will be added. There is only one group of like terms
the answer is: ab-4a-5

41/33 should be added to -15/33 (which is the same number as -5/11 but converted to have same denominator).
So answer is 41/33
Answer: 4 litres of air is held in Braydon’s tank.
Step-by-step explanation:
The law relating pressure to volume is the Boyle's law. It states that the volume of a given mass of gas is inversely proportional to its pressure as long as temperature remains constant. It is expressed as
P1V1 = P2V2
Where
P1 and P2 are the initial and final pressures of the gas.
V1 and V2 are the initial and final volumes of the gas.
From the information given,
V1 = 6 litres
P = 220 psi
P2 = 330 psi
Therefore,
6 × 220 = 330V2
V2 = 1320/330 = 4 litres
Answer:
x=-6
Step-by-step explanation:
since y varies directly with x
it means y=Kx, and k=y/x
when y=6, and x=-2
k=6/-2=-3
But when y=18, x will be given by
x=y/k
x=18/-3,. x=-6
Answer:
that expression is not factorable with rational numbers
