7 + x/4 = 5 (common denominator is 4)

4(7+x/4) = 4 x 5  (distribute the 4 though parenthesis)

4 *7 +4x/4 = 4 x 5

4 * 7 + x = 4 x 5

28 + x = 4 x 5

28 + x = 20 (subtract the 28)

x = 20 - 28

x = -8

Hello!

<u><em>Answer:⇒⇒⇒⇒⇒⇒⇒⇒⇒  x=-8</em></u>

Step-by-step explanation:

First you had subtract by 7 from both sides of equation.

7+\frac{x}{4}-7=5-7

And then simplify.

\frac{x}{4}=-2

Multiply by 4 from both sides of equation.

\frac{4x}{4}=4(-2)

Finally, simplify.

x=-8

Hope this helps!

Thank you for posting your question at here on brainly.

Have a great day!

A soccer field is 90 meters wide and 120 meters long.The coach asked the players to run from corner to corner diagonally across.
Marat540 [252]

The length of diagonal is 150 meters

<em><u>Solution:</u></em>

Given that soccer field is 90 meters wide and 120 meters long

The coach asked the players to run from corner to corner diagonally across

To find: length of diagonal

The figure is attached below

Let ABCD be a rectangle with BD as diagonal

From given,

length = DC = 120 meters

width = BC = 90 meters

The diagonal and two sides of rectangle forms a right angled triangle with diagonal as hypotenuse

Pythagorean theorem, states that the square of the length of the hypotenuse is equal to the sum of squares of the lengths of other two sides of the right-angled triangle.

By above definition, for right angled triangle DCB

BD^2 = BC^2 + DC^2

BD^2 = 90^2 + 120^2\\\\BD^2 = 8100 + 14400\\\\BD^2 = 22500

Taking square root on both sides,

BD = \sqrt{22500}\\\\BD = 150

Thus length of diagonal is 150 meters

What is the equation for shifting the standard sine curve 2 units horizontally?
ratelena [41]
     Just add the displacement value to variable. If this value is positive, the graph will move to the right, otherwise it will shift to left.

f(\O)=sen(\O+x)
 
     Where: x=displacement value

If you notice any mistake in my English, please let me know, because I am not native.

You want to make a rectangular banner that is 18ft. Long with a trim around the entire border of the banner . You have no more t
lys-0071 [83]

Answer:

6 ft

Step-by-step explanation:

Given that:

Length of rectangular banner = 18 ft

Total trim of banner available = 48 ft

To find:

Possible widths of the banner = ?

Solution:

Maximum trim available of the banner around the entire border of the banner = 48 ft

i.e. we are given the total perimeter of the rectangular banner.

Formula for perimeter of a rectangle is given as:

Perimeter = 2 \times (Length + Width)

Putting the values of perimeter and length to find the value of width.

48 = 2 \times (18 + Width)\\\Rightarrow 48 =36+2 \times Width\\\Rightarrow 2 \times Width = 48-36\\\Rightarrow 2 \times Width = 12\\\Rightarrow \bold{Width = 6\ ft}

So, width possible is <em>6ft.</em>
