Answer:
Step-by-step explanation:
Given

Find x
When the result is 4.4, we have:
This gives:
Divide both sides by 2
Square both sides
When the result is 4.5, we have:
Divide both sides by 2
Square both sides
So, the value of x is between 4.84 and 5.0625
i.e.
The only integer between the above interval is 5.
Hence:
Part A:
there is 60% of lemon juice in a 1 liter of water
so 60% *OF* the 1 liter
( of technically means * in mathematics)
so
60% * 1 liter
or 0.6 * 1 liter
Now to find the total number of liters of lemon juice and water in the bottle
(0.6*1)+x= 1
(x being the amount of water)
Part B: We can calculate the number of liters of lemon juice that are present in the bottle
60% * 1
0.6 * 1
that is 0.6
So there is 0.6 liters of lemon juice in the bottle
Hope this helps :)
Answer:x=-2
Step-by-step explanation:
distribute -6(x+7)=-30
-6x-42=-30
add 42 to both sides
-6x-42+42=30+42
simplify
-6x=12
solution x=-2
