3.56 as a fraction simplified

Artemon [7]

This has to do with place value.....the 3, since it is on the left of the decimal, is a whole number. The last number (6) is in the hundredths place..
so it is 3 56/100 which reduces to 3 14/25

X + 2y = 3 3x - 2y = 5 What is the solution to the system of equations? A) (4, 3.5) B) (2, 1 2 )) Eliminate C) (2, -1) D) ( 1 2

sp2606 [1]

Answer:

The solution is B) (2, $\frac{1}{2}$ ).

Step-by-step explanation:

This system of equations can be solved by elimination, where we add the two equations together to eliminate one of the variables and solve for the remaining variable:

x + 2y = 3

3x - 2y = 5

4x = 8 or x = 2

To solve for 'y', plug in the value of x: 2 + 2y = 3 or 2y = 1 or y = $\frac{1}{2}$

Putting the values into the point (x, y) = (2, $\frac{1}{2}$ )

The width of a rectangle is (x + 2). If its area is x4 + 2x3 + 6, find its length.

attashe74 [19]

The length of rectangle is given as $length = \frac{x^4+2x^3+6}{x+2}$

Solution:

Given that,

Width of rectangle = x + 2

Area of rectangle = $x^4+2x^3+6$

Length of rectangle = ?

The area of rectangle is given as:

$\text{Area of rectangle } = length \times width$

Therefore, length is given as:

$length = \frac{\text{Area of rectangle}}{width}$

Substituting the given values we get,

$length = \frac{x^4+2x^3+6}{x+2}$

There are no common factors that could be cancelled. Also numerator cannot be factored further

Thus length of rectangle is given as $length = \frac{x^4+2x^3+6}{x+2}$
