1. To solve x/ 0.4 = 10 You would:

liubo4ka [24]

given $\frac{x}{0.4}$ = 10

multiply both sides by 0.4 to eliminate the fraction

x = 0.4 × 10 = 4

and $\frac{4}{0.4}$ = 10

A bottle of energy drink contains 9/10 liter. Coach Donavan buys 15 bottles. How many liters of energy drink did he buy?

Verdich [7]

To find out how many liters of energy drink Coach Donavan bought you need to multiply how much liters are in one bottle by how many bottles he bought.

9/10 x 15

9/10 x 15 is 13.5 or 13 and 1/2

So Coach Donavan bought 13 and a half liters of energy drink.

<h2>The required 'option C) 144' is correct.</h2>

Step-by-step explanation:

We have,

$(x^{\dfrac{1}{8}})(x^{\dfrac{3}{8}})=12$

To find, the possible value of x = ?

∴ $(x^{\dfrac{1}{8}})(x^{\dfrac{3}{8}})=12$

⇒ $x^{\dfrac{1}{8}+\dfrac{3}{8}}=12$

Using the exponential identity,

$a^{m} a^{n} =a^{m+n}$

⇒ $x^{\dfrac{1+3}{8}}=12$

⇒ $x^{\dfrac{4}{8}}=12$

⇒ $x^{\dfrac{1}{2}}=12$

Squaring both sides, we get

$(x^{\dfrac{1}{2}})^2=(12)^2$

⇒ $x^{{\dfrac{1}{2}}\times2}=144$

⇒ x = 144

∴ The possible value of x = 144

Thus, the required 'option C) 144' is correct.
