Evaluate -x+4y when x= -4/5 and y= 1/3. write your answer as a fraction or mixed number in simplest form. the value of the expression is- i need asap! !

so we know that x= -4/5 and y= 1/3

knowing that information you can apply it into the equation -x+4y

it should look like this: -(-4/5)+4(1/3)

when you simplify those you get 4/5+ 4/3

Now you need to add them, but since they don't have the same denominator you need to find a common denominator that they both have; which is 15

You multiply 3/3 with 4/5 and you should get 12/15

You then multiply 5/5 with 4/3 and you should get 20/15

Now that they have the same denominator you then add 12/15+20/15= 32/15 (that's the answer)

answer: given that the roller coaster can accommodate 1600 riders per hour, thus the roller coaster can accomodate 1600 / 60 = 26.67 riders per minute.

given that there are 345 people in the line, the number of minutes it will take for the 345 persons to get into the roller coaster is given by 345 / 26.67 = 12.94 minutes.

therefore, it will take you 12.94 minutes to get to the front of the line.
