Answer:
Is this the whole question?
Step-by-step explanation:
Each sandbox will need 4,200 lbs of sand. 42,000/10=4,200
Answer:
11 and 12
Step-by-step explanation:
because 11 and 12 are two positive consecutive integers. and when you multiply 11 and 12 you get 132.

It is y = 3x + 2, which means the y-intercept is 2. :)
Answer:
x + y = 6
Step-by-step explanation:
Standard Form:
y - y1 = m(x - x1)
In this question, the coordinate is (1, 5) with a slope of -1 (the slope is the same as street 1 since street 2 is going to be parallel.
Insert the coordinate and slope into standard form and you'll get this:
y - 5 = -1 ( x - 1 )
y - 5 = -x + 1
y = -x + 6
y + x = 6
hope this helps.
