You have 10 cups of a cleaning solution that is 10% white vinegar and 90% water. You want the mixture to be 50% white vinegar an

lisabon 2012 [21]

Let
x-->volume of white vinegar you need to add to the mixture (measured in cups)
then
the amount of the pure vinegar in the mixture will be -----> (10*0.1 + x) cups
the volume of liquid will be ---------> 10 + x
the concentration equation is-------> [(10*0.1 + x)/(10+x)]=0.50multiply both sides by (10+x) and then simplify

(10*0.1 + x)=(10+x)*0.50-----------> 1+x=5+0.50x-------> 0.50x=4
x=8

the answer is
you need to add 8 of a cup of the pure vinegar to the mixture

Ab-ac=a(b-c)
a is common factor
find common factor
factor the numbers

24=2*2*2*3
18y=2*3*3*y

common factor is 2*3 or 6

6(4)-6(3y)=6(4-3y)

How do you solve 5v/13=25/39

TEA [102]

Solving a Single Variable Equation :

2.3 Solve : 3v-5 = 0

Add 5 to both sides of the equation :
 3v = 5
Divide both sides of the equation by 3:
 v = 5/3 = 1.667

One solution was found : v = 5/3 = 1.667
Making Equivalent Fractions : 1.3 Rewrite the two fractions into equivalent fractions

Two fractions are called equivalent if they have the same numeric value.

For example : 1/2 and 2/4 are equivalent, y/(y+1)2 and (y2+y)/(y+1)3 are equivalent as well.

To calculate equivalent fraction , multiply the Numerator of each fraction, by its respectiveMultiplier. L. Mult. • L. Num. 5v • 3 —————————————————— = —————— L.C.M 39 R. Mult. • R. Num. 25 —————————————————— = —— L.C.M 39Calculating the Least Common Multiple : 1.1 Find the Least Common Multiple

 The left denominator is : 13 

 The right denominator is : 39

 Least Common Multiple:
 39 v = 5/3 = 1.667 next

rearrange = 5*v/13-(25/39)=0

Step by step solution:part 1: 5v 25 Simplify —— - —— 13 39

Calculating Multipliers : 1.2 Calculate multipliers for the two fractions

 Denote the Least Common Multiple by L.C.M
 Denote the Left Multiplier by Left_M
 Denote the Right Multiplier by Right_M
 Denote the Left Deniminator by L_Deno
 Denote the Right Multiplier by R_Deno

 Left_M = L.C.M / L_Deno = 3

 Right_M = L.C.M / R_Deno = 1

Pulling out like terms : 1.5 Pull out like factors :

 15v - 25 = 5 • (3v - 5)
Equation at the end of step 1 : 5 • (3v - 5) ———————————— = 0 39
Step 2 : 5•(3v-5) Solve ———————— = 0 39
