Answer:

0 = 0

Step-by-step explanation:

2+5x−7=3x−9+2x

Step 1: Simplify both sides of the equation.

−2+5x−7=3x−9+2x

−2+5x+−7=3x+−9+2x

(5x)+(−2+−7)=(3x+2x)+(−9)(Combine Like Terms)

5x+−9=5x+−9

5x−9=5x−9

Step 2: Subtract 5x from both sides.

5x−9−5x=5x−9−5x

−9=−9

Step 3: Add 9 to both sides.

−9+9=−9+9

0=0

a weather balloon is released and reaches a maximum altitude of 5000 meters.A week later, the balloon is recovered at 3750 metwr
dsp73

The change in altitude between the maximum height and the height at which the balloon was recovered is 1300 meters

<h3>How to determine the change</h3>

It is important to note that the maximum height is the peak altitude the balloon reached

To find the difference, we use the formula

Change = Maximum height - recovery height

Maximum height = 5000 meters

Recovery height = 3700 meters

Substitute the values

Change = 5000 - 3700

Change = 1300 meters

Thus, the change in altitude between the maximum height and the height at which the balloon was recovered is 1300 meters

Six times a number is greater than 20 more than that number what are the possible values of that number
Degger [83]

Let n = the unknown number.

Six times a number =  6 * n = 6n

20 more than number = n + 20

Greater than = >

Put it all together:

6n > n + 20

Subtract n from both sides to get constants on one side and variables on the other:

6n - n > 20

5n > 20

Divide both sides by 5 to isolate variable N

n > 4

or (4, ∞)
