Answer:
-42-20x
Step-by-step explanation:
Use PEMDAS, which is:
P: Parenthesis
E: Exponents
M: Multiplication
D: Division
A: Addition
S: Subtraction
So first you would open parenthesis:
4x-42-24x
Then combine like terms:
4x-24x=-20x
Your answer would be -42-20x.

Answer:
When we divide by a negative value, the sign for the inequality changes.
Step-by-step explanation:
2x < -8, to solve we would divide by 2 and receive x < -4. However, in solving -2x < 8, we would divide by negative 2, which would result in x > -4. Clearly, these sequences provide opposite answers and that is a rule to inequalities, that when dividing by a negative number, we must flip the less than/greater than sign.
Substitue 2x for y in the second equation:

Answer:
To find Felicity's hourly rate you first want to find out how many hours she has babysat altogether. In order to do this we need to take 2*10=20
With that 20 we can divide it by 180 to find her hourly rate
