4/2 forms a proportion because it can be simplified further into 2.
20/6 forms a proportion because it can be simplified to 10/3
10 rows= 12 mins
there's 25 rows in all so break it down into 10, 10, and 5 to make it more simple
12+12= 24 minutes for 20 rows
since you only have 5 rows left (which is half of ten), you divide the 12 by two as well.
12mins/2= 6 minutes for 5 rows
24mins+6mins= 30 minutes
answer: It will take 30 minutes to knit 25 rows
hiii how are you feeling today

-7x=-28
-7 -7
x=4
Divide both sides by -7. A negative divided by a negative will give you a positive. So the answer would be x=4.
to determine if a triangle is a right triangle, use the pythagorean theorem
a^2 +b^2 = c^2
if this is true is it a right triangle
