Answer:
36/6, 72/12, and 6/1
Step-by-step explanation:
18/3=6, so we just need to find the fractions that simplify into 6 (we reduce fractions by dividing the numerator and denominator by the greatest common factor, in this case the number must be whole, so we are just going to divide the numerator by the denominator). 90/16=5.625, it does not equal 6, so it is not proportional to 18/3, this is also true for 36/12=3. 36/6=6 so it is proportional, so is 72/12=6 and, obviously 6/1=6 so it, too, is proportional to 18/3.
8 divided by (1/4) = 8*4 = 32 home sites
Answer:
3 galllon one is $8 because it is the only thing that you can multiply by 3 to get 24
The 4 gallon one is $9 because it is the only number that you can multiply by 4 to get 36
Step-by-step explanation:
Answer
the equation of a line that is perpendicular to −x+3y=9 is y=-3x-7
Step-by-step explanation:
Equation of given line is −x+3y=9
we write the equation in y =mx+b to find slope of given line (m)
−x+3y=9
Add x on both sides
3y = x+ 9
Divide by 3 on both sides
Slope of given line = 1/3
Slope of perpendicular line is the negative reciprocal of slope of given line
Slope of perpendicular line = -3
Perpendicular line passes through point (-3,2) that is (x1,y1)
Now we use point slope equation
y - y1 = m (x-x1)
y - 2 = -3(x-(-3))
y - 2= -3(x+3)
y -2 = -3x -9
Add 2 on both sides
y = -3x - 7
