Hi there! :)
<u>Answer:</u>
Donovan babysat for 7 hours on Saturday in order to earn $31.50.
Step-by-step explanation:
In order for you to answer your question, you'll need to use the cross product method:
$9 → 2 hours
$31.50 → X hours
<u>(2 × 31.50)</u> ÷ 9 = X hours
<u>63 ÷ 9</u> = X hours
<u>7 = X hours</u>
There you go! I really hope this helped, if there's anything just let me know! :)
x is strictly less than 2 or x ∈ (-∞, 2)
Given: inequality 5x - 7 < 2x - 1
What are inequalities?
Inequalities are statements that are represented as comparison between two or more numbers or algebraic expressions.(strictly less, strictly great, greater, lesser)
Solving the given equation:
5x - 7 < 2x - 1
=> 5x - 7 - 2x < 2x - 1 - 2x
=> 3x - 7 < -1
=> 3x - 7 + 7 < -1 + 7
=> 3x < 6
=> x < 2
Therefore, x is strictly less than 2.
Hence x ∈ (-∞, 2)
