she went 1
m у cm high.

50 cm​

Answer 1

Answer:

160 cm

Step-by-step explanation:

initial height -total final height= distance from ground

4m20cm - (1m10 cm +1mycm)= 50 cm

420cm -50cm= 110cm+1mycm

370cm-110cm-100cm= y cm

160= y cm

Answer 2

:

Step-by-step explanation:

1=100cm

4m=400cm, 1m=100cm,

first she went 400+20cm up

she came 100+10cm down

she went 100 +y cm up

now,

400-100+100=400, 20-10+y=10y

400+10y=50

10y=50-400

10y=-350

y= -350/10

y=- 35

IF U HAVE A DOUGHT U CHECK

400+10y=50

400+10×-35=50

400+(-350) =50 (+ × - is - )

400-350=50

hence proved
