So 5*4 is 20, and 20 minus 2 is 18, because you add 5 four times, which makes 20
Answer:
-49/3 and -25/3
Step-by-step explanation:
Let the numbers be represented by f and s (first and second). Then f = s - 8. Also, 2f = 3s + 9. Solve this system for f and s:
Substituting s - 8 for f in the 2nd equation, above, yields
2(s - 8) = 3s + 9, or 2s - 16 = 3s + 9. Then 3s = -25, and s = -25/3. The first number is then f = s - 8, or f = -25/3 - 8, or f = -49/3.
Answer:
1190
Step-by-step explanation:
Here, you need to add the squares of the measurements.
20² + 10² + 13² + 11² + 20² =
= 400 + 100 + 169 + 121 + 400
= 1190
