Solve For X: 12 * X+3=51

gavmur [86]

Answer:

x=4

Step-by-step explanation:

12 * X+3=51

Subtract 3 from each side

12x +3-3 = 51-3

12x = 48

Divide by 12

12x/12 = 48/12

x = 4

I need help. Find the value of each variable.

kirill [66]

Answer:

x = 14√3

y = 7√3

Step-by-step explanation:

By applying sine rule in the given triangle,

sin(60°) = $\frac{\text{Opposite side}}{\text{Hypotenuse}}$

$\frac{\sqrt{3} }{2}=\frac{21}{x}$

x = $\frac{42}{\sqrt{3}}$

x = 14√3

By applying cosine rule in the given triangle,

cos(30°) = $\frac{\text{Adjacent side}}{\text{Hypotenuse}}$

$\frac{1}{2}=\frac{y}{x}$

$\frac{1}{2}=\frac{y}{14\sqrt{3}}$

y = 7√3

Write the following expression in radical form: x^3/2

goblinko [34]

Answer:

$x\sqrt{x}$

Step-by-step explanation:

Given:

The given expression is.

$x^{\frac{3}{2}}$

Now, we need to write the given expression in radical form.

Solution:

First, we can rewrite the term as:

$x^{3\times \frac{1}{2}$

Now, we can use this rule of exponents to rewrite the term again:

$x^{a\times b} = (x^{a})^{b}$

$x^{3\times \frac{1}{2}} = (x^{3})^{\frac{1}{2}}$

Now, we can use this rule to write the term as an radical:

$x^{\frac{1}{n}} = \sqrt[n]{x}$

$(x^{3})^{\frac{1}{2}} = \sqrt[2]{x^{3}}$

$(x^{3})^{\frac{1}{2}} = x\sqrt{x}$

Therefore, the redical form of the given expression is $x\sqrt{x}$

Mine A is 225 feet underground and Mine B has an elevation of -223 feet. Which mine is further underground

LUCKY_DIMON [66]

Answer: Mine A

Step-by-step explanation: Mine A is further underground because elevation means height and when it’s shows a number that is negative that means underground. 225 is greater than 223. So Mine A is further underground.
