Actually Welcome to the Concept of the Average rate of change.
The average rate of change can be calculated by, finding the change of the two readings and getting a average between them.
here, for x =3 to x =5
1.) in the interval, x =3 to x = 4
the change is ==> 287 - 125 = 162
2.) in the interval, x = 4 to x=5
the change is ==> 549-287 = 262
Now the average ==> 162+262/2 ===> 212
Hence the average rate of change is 212
Answer:
$112.80
Step-by-step explanation:
If he earns $0.235 per pack, and there are 480 packs, then our equation is:
0.235 x 480 = $112.80
By applying the law of sines.

Given:
<span>GJ = 10 , ∠J =45° , ∠H = 31°
∴ </span><span>

∴ GH = 10 * sin 45° / sin 31° ≈ 13.7 m

Answer:
The answer is 7x
Step-by-step explanation:
To solve the problem drop the brackets and add the like terms
∵ (4x - 6) + (3x + 6)
- There is no number multiplied by each bracket so drop the
brackets without any change in the values inside them
∴ (4x - 6) + (3x + 6) = 4x - 6 + 3x + 6
- The terms 4x and 3x are like terms, so add them
∵ 4x + 3x = 7x
- The terms -6 and 6 are like terms, so add them
∵ -6 + 6 = 0
∴ 4x - 6 + 3x + 6 = (4x + 3x) + (-6 + 6)
∵ (4x + 3x) + (-6 + 6) = 7x + 0
∴ 4x - 6 + 3x + 6 = 7x
∴ (4x - 6) + (3x + 6) = 7x
The answer is 7x
