Which value for x makes the following number sentence true? 12x = 6x + 24

Mathematics

To solve this, first subtract 6x from both sides.

That is because there cannot be the same variable on both sides of the equation. The new equation would be:

6x=24

Now divide by both sides of the equation by 6

x=4

The volume of a rectangular prism is its length times width times height, or algebraically, V=lwh. You may be used to computing volume with numbers, but remember, a variable is a stand-in for a number. So you can solve this in the same way. Substitute l=x, w= \frac{x}{2},h= \frac{x}{3} into the formula for volume. You get (x)( \frac{x}{2})( \frac{x}{3} ), and you multiply these factors together. As you would with ordinary fractions, multiply the numerators and denominators across. You get \frac{(x)(x)(x)}{(1)(2)(3)} =  \frac{x^3}{6}. It seems that the book wants you to simplify by bringing the 6 up to the denominator. Recall the rule x^{-n}= \frac{1}{x^n}, if n is non-negative. The opposite applies so that \frac{1}{6} = 6^{-1}. For your final answer, you write 6^{-1}x^3. This corresponds to answer choice B.

Find the angle between the vectors u=i-9j and v=8i+5j
Katyanochek1 [597]

Answer: \cos^{-1} \left(\frac{-37}{\sqrt{7298}} \right) \approx 115.665^{\circ}

Step-by-step explanation:

u \cdot v=(1)(8)+(-9)(5)=-37\\\\|u|=\sqrt{1^{2}+(-9)^{2}}=\sqrt{82}\\\\|v|=\sqrt{8^{2}+5^{2}}=\sqrt{89}\\\\\cos \theta=\frac{-37}{\sqrt{82}\sqrt{89}}\\\\\theta=\cos^{-1} \left(\frac{-37}{\sqrt{82}\sqrt{89}} \right)\\\\\theta=\boxed{\cos^{-1} \left(\frac{-37}{\sqrt{7298}} \right) \approx 115.665^{\circ}}
