Answer:

X=-50

Step-by-step explanation:

4(x-9)-2x=3x+14

4x-36-2x=3x+14

2x-36=3x+14

-x-36=14

-x=50

-x divided by 50 makes the x postive & the 50 negative

Reduce a 24 cm by 36 cm photo to 3/4 original size.

The most logical way to do this is to keep the width-to-height ratio the same:  It is 24/36, or 2/3.  The original photo has an area of (24 cm)(36 cm) = 864 cm^2.

Let's reduce that to 3/4 size:  Mult. 864 cm^2 by (3/4).  Result:  648 cm^2.

We need to find new L and new W such that W/L = 2/3 and WL = 648 cm^2.

From the first equation we get W = 2L/3.  Thus, WL = 648 cm^2 = (2L/3)(L).

Solve this last equation for L^2, and then for L:

2L^2/3 = 648, or (2/3)L^2 = 648.  Thus, L^2 = (3/2)(648 cm^2) = 972 cm^2.

Taking the sqrt of both sides, L = + 31.18 cm.  Then W must be 2/3 of that, or W = 20.78 cm.

Check:  is LW = (3/4) of the original 864 cm^2?  YES.

Brady jogs laps around a circular park with a fountain at the center. Which table could represent Brady’s distance from the foun
olasank [31]

Answer:

A 2-column table with 5 rows. The first column is labeled time with entries 0, 2, 4, 6, 8. The second column is distance (feet) with entries 50, 50, 50, 50, 50.

Step-by-step explanation:

we know that

The radius of a circle is the distance from the center of the circle to any point on its circumference.

The radius is always constant at any point on the circle.

In this problem

A fountain represent the center of the circular park

Brady’s distance from the fountain represent the radius of the circular park

That means

Brady’s distance from the fountain after jogging around the path for a number of minutes is a constant

therefore

The answer is

A 2-column table with 5 rows. The first column is labeled time with entries 0, 2, 4, 6, 8. The second column is distance (feet) with entries 50, 50, 50, 50, 50.

The radius of the circular park is 50 feet
