Answer:
x = 1.25 represented the price of the snacks which Hannah buys each day .
Step-by-step explanation:
As given
Hannah spends $4.50 each day to buy lunch at her school.
After school each day, she buys the same snack.
Hannah spends $28.75 for lunch and snacks each week.
The equation and solution model the situation. 5(4.50 + x) = 28.75 : x = 1.25
Here x = 1.25 represented the price of same snack which Hannah buys each day .
Therefore x = 1.25 represented the price of the snacks .
Answer x = 24 + 3x
Step-by-step explanation:
Answer:
150 miles
Step-by-step explanation:
420/14 = 30 miles per hour
30 x 5 = 150 miles
<span>The infinite series whose terms are the natural numbers 1 + 2 + 3 + 4 + â‹Ż is a divergent series. The nth partial sum of the series is the triangular number
{\displaystyle \sum _{k=1}^{n}k={\frac {n(n+1)}{2}},} \sum_{k=1}^n k = \frac{n(n+1)}{2},
which increases without bound as n goes to infinity. Because the sequence of partial sums fails to converge to a finite limit, the series does not have a sum.
Although the series seems at first sight not to have any meaningful value at all, it can be manipulated to yield a number of mathematically interesting</span>
