Choices are
1/25
1/50
49/100
7/100

please help I’m confused because I got 8/10 which reduced to 4/5 but it’s not an option

Sorry guys but as you have a small brain

The length of a rectangle is x times the square root of 100. the width is one-half y more than three-halves x. given that the area of the rectangle is 125 cm2, which equation could represent the rectangle in terms of x and y? a) 5xy − 15x = 125 b) 5xy + 15x = 125 c) 15x2 − 5xy = 125 d) 15x2 + 5xy = 125

Find the maximum value of p= 4x + 5y subject to the following constraints :
