HELP WITH ACT MATH REVIEW QUESTION IMPORTANT: the depth of a pond is 180 cm and is being reduced by 1 cm per week. the depth of a second pond is 160 cm and is being reduced by 1/2 cm per week. If the depths of both ponds continue to be reduced at these constant rates, in about how many weeks will the ponds have the same depth?

Best ResponseYou've already chosen the best response.1write equations for both ponds depths pond 1: d = 180x pond 2: d= 160(0.5x) where x = number of weeks and d = depth set them equal to each other and solve for x 180x = 160(0.5x)

Best ResponseYou've already chosen the best response.0I'm just wondering i thought i would add 180 plus 160

Best ResponseYou've already chosen the best response.1nope, they're not on the same side of the equal sign so we subtract 180  0.5x = 160 subtract 180 from both sides, what do you get?

Best ResponseYou've already chosen the best response.1right, now we divide both sides by (0.5)
