Answer:
<em><u>Part A: </u></em>(40/100)*x = 1 where x is the total contents of the bottle.
<em><u>Part B</u></em>: 1.5 Liters = the Lemon Juice
Step-by-step explanation:
Part A
Let the full contents of the bottle = x
<em><u>Equation</u></em>
Since 60% of it is lemon juice, then 100% - 60% = 40% must be water.
(60/100) * x = ?? Equation for Lemon Juice. You have to solve the water first.
(40/100) * x = 1 Equation for water
Part B
(40/100) * x = 1 change the 40% to a decimal
0.4x = 1 Divide by 0.4
x = 1/0.4 = 2.5 L
Now to find out the amount of lemon juice
0.6 * 2.5 = Lemon Juice
1.5 L = the amount of Lemon Juice.
Answer:
Step-by-step explanation:
(x+6)(x+3)=9+(x+1)
= x^2+3x+6x+18
=x^2+9x+18=9(x+1)
=x^2+9x+18=9x+9
tbs = to both sides
(-9x tbs)= 9x-9x=0 so x^2+18=9
(-18tbs) = x^2=9-18 becomes x^2=-9
x=
