Each pizza cost $ 12.65
<h3>What is an Equation ?</h3>
An Equation is used in determination of unknown variables in an expression .
It is given that
Brian ordered 3 large cheese pizzas and a salad.
The salad cost $4.95
Total amount spend = $47.60
Tip = $5
The amount spend in food is $ 47.60-5
= $42.60
Let the price of Pizza is x then the equation that can be formed to determine the price of pizza is
3x + salad = 42.60
3x + 4.95 = 42.60
3x = 37.65
x = $12.65
Therefore each pizza cost $ 12.65

Let f(x) = y = 5x - 7. Then f(3) = 5(3) - 7 = 8, and f(8) = 5(8) - 7 = 33
Then the ave. r. of c. of f(x) = 5x - 7 from x = 3 to x = 8 is
33 - 8 25

Answer:
x < -5
Step-by-step explanation:
3 ( -2x - 4 ) > 18
→ Expand the brackets

-6x > 30
→ Divide both sides by -6
x < -5
