larger mixture and uses 4.5 cups of white paint, how much blue paint will she use?

The answer is 3. If you find the unit rate of white to blue paint and multiply it by 4.5 it would come out to 3.000007 or something minute like that.

How many twelfths are there in 2/3 of 3/4 more than 1/3 of 3/8 ? I know the answer already, please show how you do it .

Ok so what this means is below:
$\frac{2}{3}* ( \frac{3}{4}+ \frac{1}{3} * \frac{3}{8} )$
Now we need to follow the rules of PEMDAS:
So inside the parentheses we need to do the multiplication first 1/3*3/8=1/8
Now we need to add 3/4 to this 1/8+3/4=7/8
Now do 2/3 of the value of the parenthesis 7/8
This is 14/24 = 7/12
Therefore there are 7 twelfths

Help on logarithmic equation

$\log _{ 2 }{ \left( 3-x \right) } +\log _{ 2 }{ 5 } =2\log _{ 3 }{ 5 } \\ \\ \log _{ 2 }{ \left( 5\left( 3-x \right) \right) } =\log _{ 3 }{ \left( { 5 }^{ 2 } \right) } \\ \\ { 2 }^{ \log _{ 3 }{ 25 } }=5\left( 3-x \right) \\ \\ { 2 }^{ \log _{ 3 }{ 25 } }=15-5x\\ \\ 5x=15-{ 2 }^{ \log _{ 3 }{ 25 } }\\ \\ x=\frac { 15 }{ 5 } -\frac { { 2 }^{ \log _{ 3 }{ 25 } } }{ 5 } \\ \\ x=3-\frac { { 2 }^{ \log _{ 3 }{ 25 } } }{ 5 }$

Solve for x <br> Need help asap

Answer:

$x=55$

Step-by-step explanation:

Corresponding angles of two parallel lines are always equal. The angle on "top" of $2x+6$ corresponds with the angle marked as $x+9$ . Therefore, its measure must also be $x+9$ .

Since these two angles form one side of a line which has 180 degrees, we have the following equation:

$2x+6+x+9=180$

Combine like terms:

$3x+15=180$

Subtract 15 from both sides:

$3x=165$

Divide both sides by 3:

$x=\frac{165}{3}=\boxed{55}$
