The following box plot shows the number of years during which 40 schools have participated in an interschool swimming meet: At least how many schools have participated for more than 1 year and less than 6 years?

a
4 schools

b
8 schools

c
10 schools

d
20 schools

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

yes.. it's proven to be 36.

the answer to this is a. a^2 + b^2 = c^2
