Hey there!

Let's plug these values into the formula.

1/2(7(4))

1/2(28)

Therefore, our area would be 14 sq cm.

Solve for the following equation <br> 1/2(2 – 4x) + 2x = 13

mart [117]

Answer:

no solution

Step-by-step explanation:

1/2(2-4x)+2x=13

We simplify the equation to the form, which is simple to understand

1/2(2-4x)+2x=13

Simplifying:

+ 0.5*(2-4x)+2x=13

Reorder the terms in parentheses

+(+1-2x)+2x=13

Remove unnecessary parentheses

+1-2x+2x=+13

We move all terms containing x to the left and all other terms to the right.

-2x+2x=+13-1

We simplify left and right side of the equation.

0x=+12

0=12

The left and right sides are not equal, therefore there is no solution. This equation is invalid.

a picture 10 1/4 feet long is to be centered on a wall that is 14 1/2 feet long. How much more space is there from the edge of t

Zarrin [17]

Answer:

Length from the edge will be $=2{\frac{1}{8}}$ feet

Step-by-step explanation:

To find length we have to conver mixed fraction to improper fraction

The length of the wall $= \frac{29}{2}$

Length of picture $=\frac{41}{4}$

First we find the total length of wall remain after picture was hung to the wall.

Length of wall remain vacant $=\frac{29}{2}-\frac{41}{4}$

Taking LCM and solving we get

$=\frac{58-41}{4} =\frac{17}{4}$

Total length of wall remain vacant $=\frac{17}{4}$

As the picture to be centered in wall, therefore space feom one edge of wall will be half that of length remain vacant as the same length to be left vacant feom both sides.

Space from one edge $=\frac{17}{4} \times \frac{1}{2}$

$= \frac{17}{8}$

$=2{\frac{1}{8}}$

Length from the edge will be $=2{\frac{1}{8}}$ feet
