Step-by-step explanation:
Answer:
They are proportional
Step-by-step explanation:
Y/X represents coordinates Y being rise X being run. So Y/X is equal to rise/run. If there was a coordinate grid, if the two points created a straight line that slant to the right I would be proportional. Since all I see is rise/run= 5 they are proportional. 5 represents the slope.
Answer:
1/4
Step-by-step explanation:
15/60 = 1/4
Let x be a number and four-fifths of a number means 4/5x and then minus 2 =
4/5x - 2
three tenths of twice that number = 3/10 x 2x
the expression will be:
4/5x-2>3/10 x 2x
4/5x-2>3/5x
4/5x - 3/5x > 2
1/5x > 2
x > 10
