Answer:
for question one - x = 12
Step-by-step explanation:
a triangle is always 180, in other words you will add all the corners equal to 180
ex (for first question) - 7x -2 + 4x + 5x - 10 = 180
you add like terms, the x with x and single numbers with numbers, which results in 16x - 12 = 180. then you do the original operation "what you do to one sign of the equal side you do to the other"
A square field that is 1/4 mile long and 1/4 mile wide has area

So, to know how many of these fields fit in the biggest field, you have to divide their areas:

So, if the farmer divides his land into square fields that are 1/4 mile long and 1/4 mile wide, he will have 16 of these smaller fields.
Answer:
...
Step-by-step explanation:
You can either make a table using any numbers you would like (I would suggest -5 to 5) and then graphing the rule
ex. (7/2)(-5)-2 = -19.5 (I multiplied (7/2) by -5 and then subtracted 2)
Or you can put the rule in a graphing calculator and check the points from there
