Final Answer:
1. The expression -20 / g evaluates to -4 when g = 5.
2. When h = -45, the expression 90 / h becomes -2.
3. h / f equals 3 with h = -45 and f = -15.
4. The result of fg / 25 is -3 for f = -15 and g = 5.
5. (f - h) / 10 is 3 when f = -15 and h = -45.
6. The expression (g - 5) / (-1) simplifies to 0 with g = 5.
7. With f = -15, h = -45, and g = 5, (f + h) / (-g) equals 12.
8. -f / g results in 3 when f = -15 and g = 5.
9. When h = -45, g = 5, and f = -15, (h - 3g) / f evaluates to 0.
Step-by-step explanation:
Let's substitute the given values of f , g, and h into the expressions:
1. -20 / g
Substitute g = 5 :
-20 / 5 = -4
2. 90 / h
Substitute h = -45:
90 / (-45) = -2
3. h / f
Substitute h = -45 and f = -15 :
(-45) / (-15) = 3
4. fg / 25
Substitute f = -15 , g = 5 :
(-15 × 5) / 25 = -3
5. (f - h) / 10
Substitute f = -15, h = -45:
(-15 - (-45) / 10 = 3
6. (g - 5) / (-1)
Substitute g = 5 :
(5 - 5) / (-1) = 0
7. (f + h) / (-g)
Substitute f = -15, h = -45, g = 5:
(-15 + (-45) / (-5) = 12
8. -f / g
Substitute f = -15 , g = 5:
-(-15) / 5 = 3
9. (h - 3g) / f
Substitute h = -45, g = 5, f = -15 :
(-45 - 3 × 5) / (-15) = 0
So, the evaluated expressions are:
1. -4
2. -2
3. 3
4. -3
5. 3
6. 0
7. 12
8. 3
9. 0
