Answer:
2.69≤x≤17.31
Step-by-step explanation:
Lety the amount in the other Piggy bank be x.
The difference in the amount of money between the two banks is no more than $10 is expressed as;
|x-7.31| ≤ 10
The value in the modulus sign can be positive or negative
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
Answer:
-9
Step-by-step explanation:
Answer:
W = 5 ft; L = 10 ft
Step-by-step explanation:
Start by representing the length and width:
W = W
L = 2W
Area of rectangle = L * W = 2W * W = 50 ft^2. Then 2W^2 = 50 ft^2.
Solving for the width W results in W^2 = 25 ft, or W = 5 ft.
The length, L, is therefore L = 2W = 10 ft.
Check: Does L * W = 50 ft^2? Does (5 ft)(10 ft) = 50 ft^2? YES
