Answer: The required number is 16.

Step-by-step explanation: We are given to find the number such that $\dfrac{3}{4}$ times of that number is equal to 12.

Let the required number be represented by x.

Then, according to the given information, we have

$\dfrac{3}{4}\times x=12\\\\\Rightarrow 3x=48\\\\\Rightarrow x=\dfrac{48}{3}\\\\\Rightarrow x=16.$

Thus, the required number is 16.

What is 12/3? 4.
What is 4x4? 16
So 3/4 x 16 = 12 because 12 is 3/4 of 16

We created this inequality to represent how Amy can meet her revenue goals:

brilliants [131]

Answer:

x = 2

Price = $29

Step-by-step explanation:

If x is the number of $2 dollars increases, then the minimum number of increases required to meet her goal is:

$-100x^2 + 15,750x + 212,500 \geq 243,600\\-100x^2 + 15,750x -31,100\geq 0\\x^2 -157.5x + 311\geq 0\\x=\frac{157.5\pm\sqrt{157.5^2-(4*1*311)} }{2}\\ x_1= 2\\x_2=155.5$

The only realistic value is x = 2 $2 increases

If the original price was $25, then the new rice required to reach Amy's goal is:

$P=25+2*2\\P=\$29$

The minimum ticket price is $29.

Solve for x and why please using these!!!

krok68 [10]

Answer:

$x = 40$

$y = 5$

Step-by-step explanation:

$4x = 2x+80\\2x = 80\\x = 40$

Edit: Solve for Y

A straight line is 180 degrees so one side (the x side) is 160°, The Y side is 20, and you can work backwards by -

$8y - 20 = 20\\8y = 40\\y = 5$
