During the summer, mark works on his uncle's horse farm. one of mark's many chores is to load bales of hay onto a wagon and haul them from the field into the barn. the proportional relationship between the number of wagon loads, x, and the number of bales of hay mark can haul, y, can be modeled by the equation y = 12x.

if mark hauled 60 bales of hay to the barn, how many wagon loads did it take?

a) 4
b) 4 1/2
c) 5
d) 5 1/2

C) 5

Step-by-step explanation:

Hi, to answer this question we have to substitute y=60 in the equation given and solve for x.

y = 12x.

Where:

x= wagon loads

y= number of bales

Replacing with the value of y given

60= 12 x

Solving for x:

60/12=x

5=x

So, the correct answer is C) 5.

Feel free to ask for more if needed or if you did not understand something.

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8  

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
