Answer: 7x + 70
Step-by-step explanation:
<em><u>Answer:</u></em>
3n = 6n + 28
<em><u>Explanation:</u></em>
The number we are dealing with is "n"
<u>We will proceed by converting the English into Math:</u>
1- Three times the number = 3 * n = 3n
2- Six times the number = 6 * n = 6n
3- 28 more than 6 times the number means that we will add 28 to the value 6n. This will give 6n + 28
<u>Finally, we are given that:</u>
3n is the same as (6n + 28). This means that they are both equal.
<u>Therefore, our equation would be:</u>
3n = 6n + 28

Answer: it will trave 56.89 meters before coming to rest.
Step-by-step explanation:
This is a geometric progression since the distance travelled (height) by the ball is reducing by a constant ratio, r. Since the number of times that the ball will bounce is infinite, then we would apply the formula for determining the sum of the terms in a geometric progression to infinity which is expressed as
S = a/(1 - r)
where
S = sum of the distance travelled by the ball
a = initial distance or height of the ball
r = common ratio
From the information given,
a = 128/9
r = (32/3)/(128/9) = 0.75
Therefore,
S = (128/9)/(1 - 0.75) = 56.89 meters
