Question

Points D and E are aligned with a ruler. Point D is at the mark for 4.5 cm, and the distance between points D and Eis 3.4 cm. At which two marks on the ruler could point E be located? 0 cm or 3.4 cm 0 -3.4 cm or 0 cm 1.1 cm or 7.9 cm 0 -7.9 cm or 1.1 cm​

Answer 1

1.1 cm or 7.9 cm

Explanation:

Given:

Point D mark for 4.5 cm

Distance between points D and E =3.4 cm

Find:

Location of point E

Computation:

Assume;

Point o = 0 cm mark

Point E = Point D mark - Distance between points D and E

Point E = 4.5 cm - 3.4 cm

Point E = 1.1 cm

or

Point E = Point D mark + Distance between points D and E

Point E = 4.5 cm + 3.4 cm

Point E = 7.9 cm
