Answer:
10 pounds of potatoes would cost $15.
Step-by-step explanation:
Set up proportion.
4/6=10/x
simplify 4/6 into 2/3,
2/3=10/x

a = 1
Answer:
the second one
Step-by-step explanation:
Hello There!
The area of a triangle can be found using this formula

where a and b = bases and h = height
The trapezoid shown has the following dimensions
top base = 9cm
bottom base = 14 cm
height = 12 cm
slant height = 13 cm
using this information, we plug in the values into the formula
So 
the equation we created matches the 2nd equation therefore the second one is your answer
