  • Question 1 (request help)

    A taxi cab costs $1.50 for the first mile and $0.75 for each additional mile. Which equation could be solved to find how many miles you can travel in a taxi for $10, given that x is the number of additional miles?
    • \(1.5\text{x} + 0.75 = 10\)
    • \(0.75\text{x} + 1.5 = 10\)
    • \(1.5\text{x} - 0.75 = 10\)
    • \(0.75\text{x} - 1.5 = 10\)
  • Question 2 (request help)

    Which is the solution of \(\frac{t}{2.5} = -5.2\)?
    • -13
    • -2.08
    • 2.08
    • 13
  • Question 3 (request help)

    Which expression is equivalent to \(5\text{x} - 30\)?
    • \(5(\text{x} - 30)\)
    • \(5(\text{x} - 6)\)
    • \(5\text{x}(\text{x} - 6)\)
    • \(\text{x}(5 - 30)\)
