Answer:
AC = 7.5 cm
CB=10.5 Cm
Step-by-step explanation:
Given that point C in between point A and B
AB= 18 cm
lets distance between CA = x
then distance between CB will be =x +3
Also give that AB =18 cm
So by adding CA and AB
x + x +3 =18
2 x =15
So x=7.5 cm
So
AC = 7.5 cm
CB=10.5 Cm
The measure of AC and CB are 7.5 and 10.5 respectively
The distance between two points on a graph is known as a line.
If C is on a point AB, then;
AC +CB = AB ................. 1
If the distance from C to A is 3 cm shorter than the distance to B, then:
AC = CB - 3 .................. 2
Substitute equation 2 into 1 to have;
AC +CB = AB
CB - 3 +CB = AB
2CB - 3 = 18
2CB = 18 + 3
2CB = 21
CB = 21/2
CB = 10.5
Recall that AC = CB - 3
AC = 10.5 - 3
AC = 7.5
Hence the measure of AC and CB are 7.5 and 10.5 respectively
