Respuesta :
let's call the weight of an ostrich o=180.
we know that o=20+4*k, or, if we substitute o for 180: 180=20+4*k
where k is the weight of a kiwi.
if we want to know k, we have to subtract 20 from both sides of the equation first:
160=4*k
and divide them by 4:
40=k
So a kiwi is 40 inches high.
we know that o=20+4*k, or, if we substitute o for 180: 180=20+4*k
where k is the weight of a kiwi.
if we want to know k, we have to subtract 20 from both sides of the equation first:
160=4*k
and divide them by 4:
40=k
So a kiwi is 40 inches high.
