Sagot :
1) Sally is 1.63 m tall and Anna is 1.53 m tall
2) 1/5 of $50 is $10 (just divide 50 by 5)
10% of $40 is $4 (multiply 40 by 0.1)
2) 1/5 of $50 is $10 (just divide 50 by 5)
10% of $40 is $4 (multiply 40 by 0.1)
1) you should let x be Anna's height and (x+0.1) will be sally's height
.
x + x + 0.1 =3.16
2x=3.16-0.1
2x=3.06
x=3.06/2
X=1.53
So anna's height is 1.53m and sally's is 1.53+0.1=1.63m.
This is how u do it hope it helped:)
