Answer:
8.2.69 ≤ x ≤ 17.31
11. x-7.31 ≤ 10
12. x≤17.31
Let the amount in the other Piggybank be x.
If positive;
x-7.31 ≤ 10
x ≤ 10+7.31
x ≤ 17.31
If negative
-(x-7.31) ≤ 10
-x+7.31 ≤ 10
-x ≤ 10-7.31
-x ≤ 2.69
Multiply both sides by -1
x ≥ -2.69
The compound inequality representing the amount of money in the other bank is -2.69≤x≤17.31
Step-by-step explanation:
Answer:
(C) 1/2
Step-by-step explanation:
If 4s is 2 more than 4t, then:
- 4s = 2+ 4t
- 4s - 4t = 2
- 4s/4 - 4t/4 = 2/4
- s - t = 1/2
(C) is the answer
5x + 25 < 85
5x < 60
x < 12
