Let’s solve each equation one by one. We’ll find the value of “n” in each case.
---
First card: n + 6 = 30
To find n, we subtract 6 from both sides:
n = 30 - 6
n = 24
✔ Check: 24 + 6 = 30 → Correct!
---
Second card: A number and six is thirty.
This means the same as the first card: n + 6 = 30
So again, n = 24
✔ Same answer — makes sense!
---
Third card: 6 × n = 30
To find n, divide both sides by 6:
n = 30 ÷ 6
n = 5
✔ Check: 6 × 5 = 30 → Correct!
---
Fourth card: Six times a number is thirty.
Same as above: 6 × n = 30 → n = 5
✔ Again, matches!
---
Fifth card: 30 ÷ n = 6
We need to find what number you divide 30 by to get 6.
That means: n = 30 ÷ 6
n = 5
✔ Check: 30 ÷ 5 = 6 → Correct!
---
Sixth card: Thirty divided by a number is six.
Same as above: 30 ÷ n = 6 → n = 5
✔ Matches!
---
Seventh card: n - 30 = 6
Add 30 to both sides:
n = 6 + 30
n = 36
✔ Check: 36 - 30 = 6 → Correct!
---
Eighth card: A number minus thirty is six.
Same as above: n - 30 = 6 → n = 36
✔ Perfect match!
---
Now let’s list all answers clearly:
- Cards 1 & 2 → n = 24
- Cards 3, 4, 5, 6 → n = 5
- Cards 7 & 8 → n = 36
Final Answer:
The values of n are: 24, 24, 5, 5, 5, 5, 36, 36 (in order from top left to bottom right).
