Solution of 3 |v-3| =9

Answer:

S=\left \{ 0\:or\:6 \right \}

Step-by-step explanation:

Absolute value equation has one property that explains why we'll have two solutions for that equation:

|a|=-b \Rightarrow a=-b\:and\:a=b

3|v-3|=9

Dividing by three to simplify it:

3|v-3|=9\\\frac{3|v-3|}{3}=\frac{9}{3}\Rightarrow |v-3|=3\\|v-3|=3\\

Applying that property over here, the absolute value is equal to one value and its symmetrical one. Notice that when we take the bars out v-3=3 and v-3=-3.

v-3=-3\Rightarrow v=-3+3\Rightarrow v=0\\v-3=3\Rightarrow v=3+3 \Rightarrow v=6\\S=\left \{ 0\:or\:6 \right \}

What is 1/6x=4 in solving equations with rational coefficients
Debora [2.8K]
To solve an equation with a rational (fraction) coefficient you need to multiply both sides of the equation by the reciprocal (invert the fraction - flip it).

\frac{1}{6}x =4 The reciprocal of 1/6 is 6/1 or 6
6( \frac{1}{6} x)= 6(4)  The product of reciprocals equals 1 
1x = 24
x = 24

This is not my answer, someone else answered this question before.

red:green

5:3
5+3=8
8 units
4qt=8 units
divide by 8
0.5qt=1unit
5 unit=red
5*0.5=2.5qt, red=2.5qt
3unit=lime
0.5*3=1.5qt
1.5qt, 2/3 of that is yellow, 1/3 is blue, 1.5 times 2/3=1, 1.5 times 1/3=0.5
result:
2.5qt red
1qt yellow
0.5qt blue
