Im not 100% that thats correct but im pretty sure it is.
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:
4n + 8 = -48
n = -14
Step-by-step explanation:
Using key words from the problem, you can set up an equation with the proper operations to solve for the variable. Product = multiplication, so the 'product of 4 and a number' = 4n. Increased = addition, so increased by 8 = 4n + 8. The word 'is' means equal to, so:
4n + 8 = -48
In order to solve for 'n', you use inverse (opposite) operations and whatever you do to one side of the equation, you do to the other:
Subtract 8: 4n + 8 - 8 = -48 - 8 or 4n = -56
Divide 4: 4n/4 = -56/4
Solve for 'n': n = -14
Answer (x-1) (x+2)
So yeah that’s my answer
