Let’s solve the “Check-Up Algebra” table step by step.
We are told:
> Julie and John have the same birthday, June 4th, but Julie is 5 years older than John.
That means:
→
Julie’s age = John’s age + 5
or
→
John’s age = Julie’s age - 5
Also, the difference between their ages is always
5, because Julie is always 5 years older — no matter how old they get, that gap doesn’t change.
---
Now let’s fill in the table row by row.
The table has three columns:
- Julie’s Age
- John’s Age
- The Difference Between Their Ages
We’ll use the rule:
John’s Age = Julie’s Age - 5
and
Difference = 5 (always)
---
Row 1: Julie’s Age = 7
→ John’s Age = 7 - 5 =
2
→ Difference =
5
Row 2: John’s Age = 4
→ Julie’s Age = 4 + 5 =
9
→ Difference =
5
Row 3: Julie’s Age = 17
→ John’s Age = 17 - 5 =
12
→ Difference =
5
Row 4: John’s Age = 25
→ Julie’s Age = 25 + 5 =
30
→ Difference =
5
Row 5: Julie’s Age = 30
→ John’s Age = 30 - 5 =
25 ← Wait! This matches Row 4? Let’s check.
Actually, looking at the table again:
In Row 5, Julie’s Age is given as
30, so John’s Age should be
25 — which is already filled in Row 4 for John’s Age when Julie was 30? That seems like a repeat or maybe a typo in the problem setup? But let’s follow the pattern.
Wait — actually, looking at the original table structure from the image description:
It shows:
| Julie's Age | John's Age | The Difference Between Their Ages |
|-------------|------------|----------------------------------|
| 7 | | |
| | 4 | |
| 17 | | |
| | 25 | |
| 30 | | |
| | 56 | |
| 93 | | |
So we need to fill in the blanks based on what’s given.
Let me reorganize with positions:
Row 1: Julie = 7 → John = ? → Diff = ?
Row 2: Julie = ? → John = 4 → Diff = ?
Row 3: Julie = 17 → John = ? → Diff = ?
Row 4: Julie = ? → John = 25 → Diff = ?
Row 5: Julie = 30 → John = ? → Diff = ?
Row 6: Julie = ? → John = 56 → Diff = ?
Row 7: Julie = 93 → John = ? → Diff = ?
But wait — in the user’s text version, it says:
> Julie’s Age | John’s Age | The Difference Between Their Ages
> 7 | |
> | 4 |
> 17 | |
> | 25 |
> 30 | |
> | 56 |
> 93 | |
And then below:
“What is the rule?”
“Julie’s age - 5 = John’s Age” or “y - 5 = John’s age”
“John’s age + 5 = Julie’s Age” or “y + 5 = Julie’s age”
So yes — consistent rule: Julie is always 5 years older.
So let’s compute each missing value:
---
Row 1: Julie = 7
→ John = 7 - 5 =
2
→ Difference =
5
Row 2: John = 4
→ Julie = 4 + 5 =
9
→ Difference =
5
Row 3: Julie = 17
→ John = 17 - 5 =
12
→ Difference =
5
Row 4: John = 25
→ Julie = 25 + 5 =
30
→ Difference =
5
Row 5: Julie = 30
→ John = 30 - 5 =
25 ← same as Row 4? That’s okay — maybe just showing both directions.
Wait — if Row 4 has John = 25 → Julie = 30, then Row 5 has Julie = 30 → John = 25 — that’s the same pair. Maybe it’s intentional to show symmetry? Or perhaps a formatting error? But mathematically, it’s correct.
Row 6: John = 56
→ Julie = 56 + 5 =
61
→ Difference =
5
Row 7: Julie = 93
→ John = 93 - 5 =
88
→ Difference =
5
---
So now, filling the entire table:
| Julie's Age | John's Age | The Difference Between Their Ages |
|-------------|------------|----------------------------------|
| 7 | 2 | 5 |
| 9 | 4 | 5 |
| 17 | 12 | 5 |
| 30 | 25 | 5 |
| 30 | 25 | 5 | ← duplicate? But mathematically correct
| 61 | 56 | 5 |
| 93 | 88 | 5 |
Wait — in Row 5, Julie is 30, John is 25 — which is the same as Row 4 where John is 25
