The numerator of a given number is 4 less than the denominator. if 5 is added to both numerator and denominator, the resulting fraction is equivalent to 5/7. What is the original fraction? Pl help fast

5/9

Step-by-step explanation:

x/y  = original fraction

x = y-4

y-4+5 / y+5 = 5/7 which is the same as =

cross-multiply to get:

7(y+1) = 5(y+5)

7y+7 = 5y+25

2y + 7 = 25

2y = 18

y = 9

x = 9-4 or 5

x/y = 5/9

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75
