Answer:
20, increased, Bianca
Step-by-step explanation:
First one:
He is shown to have travelled 20km in 1 hour, so that's 20km/h.
Second:
The gradient is how steep the curve is, the steeper the faster the person is travelling. Due to the fact Bianca's curve becomes steeper, it shows she is travelling faster. Therefore, her running speed increases.
Third:
Bianca's line hits 50km before Alberto, so therefore she finished first.
Let me know if this makes sense, hope it helped! :D

Answer:
x=−12
Step-by-step explanation:
Let's solve your equation step-by-step.
5x+6=2(2x−3)
Step 1: Simplify both sides of the equation.
5x+6=2(2x−3)
5x+6=(2)(2x)+(2)(−3)(Distribute)
5x+6=4x+−6
5x+6=4x−6
Step 2: Subtract 4x from both sides.
5x+6−4x=4x−6−4x
x+6=−6
Step 3: Subtract 6 from both sides.
x+6−6=−6−6
