Let d be the number of days the athlete spends training and t be the total number of minutes the athlete trains.
Since the athlete trains for 95 min each day, the total number of minutes can be expressed as:
t = 95d
We are given that the athlete trains for 855 min, so the equation becomes:
855 = 95d
An athlete trains for 95 min each day for as many days as possible. Write an equation that relates the number of days d that the athlete spends training when the athlete trains for 855 min.

Use mental math to find the solution of the equation.
15+d=19
d=?
15+d=19
d=?
To find the value of d, we can subtract 15 from both sides of the equation:
d = 19 - 15
Simplifying, we get:
d = 4
Therefore, the value of d is 4.
d = 19 - 15
Simplifying, we get:
d = 4
Therefore, the value of d is 4.
Use a table to find the solution of the equation.
7a-9=19
a=?
7a-9=19
a=?
Let's create a table to find the solution of the equation:
| a | 7a - 9 |
|---|--------|
| 0 | -9 |
| 1 | -2 |
| 2 | 5 |
| 3 | 12 |
| 4 | 19 |
| 5 | 26 |
From the table, we can see that when a is equal to 4, the expression 7a - 9 becomes equal to 19. Therefore, the solution to the equation 7a - 9 = 19 is a = 4.
| a | 7a - 9 |
|---|--------|
| 0 | -9 |
| 1 | -2 |
| 2 | 5 |
| 3 | 12 |
| 4 | 19 |
| 5 | 26 |
From the table, we can see that when a is equal to 4, the expression 7a - 9 becomes equal to 19. Therefore, the solution to the equation 7a - 9 = 19 is a = 4.
Use a table to find the solution of the equation. If the solution lies between two consecutive integers, identify those integers.
13.3=4n-3
If the solution is an integer, type this integer. Otherwise, type the two consecutive integers between which the solution lies.
13.3=4n-3
If the solution is an integer, type this integer. Otherwise, type the two consecutive integers between which the solution lies.
Let's create a table to find the solution of the equation:
| n | 4n - 3 |
|---|--------|
| 0 | -3 |
| 1 | 1 |
| 2 | 5 |
| 3 | 9 |
| 4 | 13 |
| 5 | 17 |
From the table, we can see that when n is equal to 4, the expression 4n - 3 becomes equal to 13. Therefore, the solution to the equation 13.3 = 4n - 3 is n = 4. The solution is an integer.
| n | 4n - 3 |
|---|--------|
| 0 | -3 |
| 1 | 1 |
| 2 | 5 |
| 3 | 9 |
| 4 | 13 |
| 5 | 17 |
From the table, we can see that when n is equal to 4, the expression 4n - 3 becomes equal to 13. Therefore, the solution to the equation 13.3 = 4n - 3 is n = 4. The solution is an integer.

| 0 | -3 |
| 1 | 1 |
| 2 | 5 |
| 3 | 9 |
