so...
2x + 13
The answer is D
Since 4 pounds of flour costs $2.60, we have that:

Where x is the amount of flour you get for 1 dollar.
We can rewrite the expression above as follows:

Then, we get 1.54 pounds of flour per dollar
Answer:
5.9km
Step-by-step explanation:
this would b solved using Pythagoras theorem
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
1.2² + 5.8² = c²
1.44 + 33.64 = c²
35.08 = c²
c = 5.9 km
