Answer:
The required expression would be
Step-by-step explanation:
Since, the amount formula is,
Where,
P = invested amount,
t = number of periods,
r = rate per period,
Given,
The invested amount at month 1, P = 4,
Number of periods from month 1 to month 4, t = 3
Amount at the end of fourth month, A = 256.
By substituting the values,
Hence, the amount of money at the end of t months.
m + 4 = 5m - 12
Subtract m from both sides.
4 = 4m - 12
Add 12 to both sides
16 = 4m
Divide both sides by 4
m = 4
Ok, if you roll the dice once - you'll get:
1, 2, 3, 4, 5 or 6.
If you roll it twice, you can get one of these combinations:
1,1 - 1,2 - 1,3 - 1,4 - 1,5 - 1,6
2,1 - 2,2 - 2,3 - 2,4 - 2,5 - 2,6
3,1 - 3,2 - 3,3 - 3,4 - 3,5 - 3,6
4,1 - 4,2 - 4,3 - 4,4 - 4,5 - 4,6
5,1 - 5,2 - 5,3 - 5,4 - 5,5 - 5,6
6,1 - 6,2 - 6,3 - 6,4 - 6,5 - 6,6
Here there are 36 combinations in total. Your chance of getting a 5 and a 2 is 1/36.
5,2 only appears once in this list of possible combinations. 2,5 doesn't count (as 2 would come up first).
Answer:
After 4 hours of renting the bus both companies would charge 300 dollars.
An equation that relates the number of bags, x, to the cost, y is <u>y = 5x.</u>
<h3>What is an equation?</h3>
An equation is a mathematical statement that claims that the two sides are equal.
An equation involves two or more variables that require some mathematical operations to obtain their equivalent value.
Therefore, an equation contains numbers, variables, and operators, which show a value after the mathematical operations.
<h3>Data and Calculations:</h3>
Let the number of bags for the class = x (number of students)
Let the unit cost of a bag = $5
Let y = the total cost
Equation, <u>y = 5x</u>
Thus, an equation that relates the number of bags, x, to the cost, y is <u>y = 5x.</u>
