Answer:
0.58
Step-by-step explanation:
The first approach to solving the question above is to find the product of 0.3 and 0.4 thus:
Next step is to find the sum of 0.3 and 0.4 thus:
The final step is to find the difference between the two results. Thus:
Therefore, the product of 0.3 and 0.4 subtracted from the sum of 0.3 and 0.4 is 0.58
Answer:
x = 2.5 or 7.5
Step-by-step explanation:
Subtract 3/4.
|5 -x| = 10/4 = 2.5
This resolves to two equations:
- 5 -x = 2.5 ⇒ x = 5 -2.5 = 2.5
- 5 -x = -2.5 ⇒ x = 5 +2.5 = 7.5
The solutions are x = 2.5 or 7.5.
