Anyone know how to solve this? would really help a lot, i'm also in a bit of a rush as well

function for height (males): y=1.875x+81.25

function for height (females): y=1.95x+73.3

There is no inverse for these functions, so you need to use unit rates. Plugging in x=50, the height is 175.5 cm

Hope this helps

so, converting firstly the mixed fractions to improper fractions and then "adding".
