Percy delivers pizzas for pizza king. He is paid $6 an hour plus $2.50 for each pizza he delivers. Percy earned $280 last week.
Triss [41]
Hey You!

6 × 30 = 90

280 - 90 = 190

190 / 2.50 = 76

We can check using multiplication.

2.50 × 76 = 190

Percy delivered 76 pizzas.

Where does the section of the bridge meet ground level? Solve 0 = -x2 + 10x - 8
djverab [1.8K]
In can be less mental effort if the equation is multiplied by -1 first.
.. x^2 -10x +8 = 0
.. x^2 -10x +25 +8 -25 = 0
.. (x -5)^2 = 17
.. x -5 = ±√17
.. x = 5 ±√17

The values of x that satisfy the given equation are
.. x = 5 -√17 ≈ 0.877
.. x = 5 +√17 ≈ 9.123
