Kelvin has 14 more foreign stamps than local stamp.
Step-by-step explanation:
Given,
Total number of stamps = 112
Ratio of local stamps to foreign stamps = 7:9
Let,
The number of local stamps = 7x
The number of foreign stamps = 9x
Therefore,
Number of local stamps = 7x = 7(7) = 49
Number of foreign stamps = 9x = 9(7) = 63
Difference = 63 - 49 = 14
Kelvin has 14 more foreign stamps than local stamp.

In plain and short, we'll simply divide 180 by (4+5+9), and give 4 pieces of those to the ratio of 4, 5 to the ratio of 5 and 9 to the ratio of 9, thus
If the area was 16cm^2 before, then each side was 4 cm long since each side of a square is equal, and the area for a square is the length of the sides squared. The square root of 16 is 4, so that is why the sides were 4 cm. When you make each side 1 cm shorter, they're now all 3 cm. 3^2 is 9, so the new area is 9 square centimeters.

Answer:
x = 850
Step-by-step explanation:
312·85 + 689·85 - 100x = 85
Divide the whole equation by 85:
312 + 689 - ¹⁰⁰/₈₅.x = 1
1001 - 1 = ²⁰/₁₇.x
x = ¹⁷/₂₀·1000
x = 50 × 17
x = 850
