Can someone please help me with this question?? It’s really hard and once you understand it, can you please give me an explanati

Thepotemich [5.8K]

We want to subtract 8x + 3 from -2x+5. We can create an expression to represent this.

-2x + 5 - (8x + 3).

After this, lets distribute the - sign (think of this like expanding something with -1).

-2x + 5 - 8x - 3

Lastly, we just need to combine like terms.

-2x + 5 - 8x - 3

Combine the 5 and -3 to get 2.

-2x + 2 - 8x

Combine the -2x and -8x to get -10x.

-10x + 2

The final answer to the question is therefore A.

Find the length of each arc r=13 ft x=90 degrees

VladimirAG [237]

Answer:

$13\pi/2$

Step-by-step explanation:

The formula of the circumference of a circle is $2\pi r$ .

The length of an arch can be found by using the ratio of circumference to the arc.

First, find the circumference of the circle:

$2\pi *13=26\pi$

Then you find the ratio:

The length of the arc is 90/360, which is 1/4, of the circumference.

Finally, find the length of the arc:

$26\pi*1/4=(13/2)\pi$ or $13\pi/2$

I hope this helps :)

Answer:

Fraction

Step-by-step explanation:

Fraction is a symbol that represents a part of a whole. It consists of a numerator and a denominator. The numerator is the number above the fraction bar (also known as "Vinculum), while the denominator is the number below the fraction bar. The denominator is the total number of equal parts in a whole.

Examples of Fraction: $\frac{1}{2}$ , $\frac{2}{7}$ and $\frac{5}{8}$ .

In the first example, $\frac{1}{2}$ , 1 is the numerator, while 2, is the denominator.

Additional Information

When the numerator is smaller than the denominator, the fraction is called "proper fraction." On the contrary, when the numerator is bigger than the denominator, the fraction is called "improper fraction."
