Answer:

$\boxed{ \bold{ \huge{ \sf{x = 29}}}}$

Step-by-step explanation:

$\sf{ - 3(3 + x) + 4(x - 6) = - 4 }$

Distribute -3 through the parentheses

Similarly, Distribute 4 through the parentheses

⇒ $\sf{ - 9 - 3x + 4x - 24 = - 4}$

Collect like terms

⇒ $\sf{x - 9 - 24 = - 4}$

Calculate

⇒ $\sf{x - 33 = - 4}$

Move 33 to right hand side and change it's sign

⇒ $\sf{x = - 4 + 33}$

Calculate

⇒ $\sf{x = 29}$

Hope I helped!

A student needed to prepare 500mL of 1X TAE buffer to run a QC gel. The stock solution in the lab is 5X TAE. What volumes of sto

Xelga [282]

Answer:

you need 100ml of 5X TAE and 400ml of water.

Step-by-step explanation:

You need to use a rule of three:

$C_1V_1=C_2V_2$

where:

$\left \{ {{C_1= 5X} \atop {C_2=1X}} \right.$

and

$\left \{ {{V_1 = V_{TAE}} \atop {V_2=500ml}} \right.$

Therefore:

$V_{TAE} = \frac{V_2*C_2}{C_1}$

$V_{TAE} = 100ml$

Then just rest the TAE volume to the final Volume and you get the amount of water that you need to reduce the concentration.
