I am not sure if the “+” was supposed to go there or if that was just a typo, so I do apologize if this is wrong... but if it doesn’t belong in the equation at all, 20 = 2X is a fairly simply multiplication problem. You are to divide both sides by the 2 and you should get X = 10, because 2 goes into 20, 10 times; and the 2 goes into 2 only once, therefore the 2 now gets cancelled out.
Answer: 20 divided by 2 = 2x divided by 2 is now 10 = X.
Really hope this helps you, have a good day :)
Simply substitute the value of
3
given. In other words,
f
(
3
)
is the function of
f
(
x
)
, however, in this case,
x
is
3
f
(
3
)
=
3
(
3
)
−
4
Distribute
3
through the parenthesis
f
(
3
)
=
9
−
4
Simplify
f
(
3
)
=
5
so, 7 is neutral anything past 7 is considered basic.
answer: <em>a water and ammonia solution with a pH of 11 (very basic).</em>
<em />any number under 7 is acidic and of course there are different degrees of acidic just like there are different degrees of basicity.
______________________________________________________________
- stomach's digestive juices, would be considered very acidic
-apple juice is also acidic but not as acidic like stomach juices.
- grape juice, is becoming less acidic.
