In a word problem, what does "is" represent? in math

It could mean a ratio of a number. for example, i could say 30 percent of bag or marbles IS red.

Hi! mark me brainliest if i : )y = 0.213x – 352.0    represents this linear model shown in the data table.plug in the values of x into the equation for a double check.let's try 1980.y = 0.213(1980) – 352.0y = 69.74which is closest to the 70.1 whereas other options do not satisfy the condition.
