The question mentions to put AC and CB into a ratio.
AC:CB
1:3
The sum of the ratio is 1+3 = 4.
Line segment = 28cm
28 / 4 = 7
Now multiply the both sides of the ratio AC:CB by 7.
AC = 1 x 7
AC = 7
CB = 3 x 7
CB = 21
So the answer must be the second one.
Answer:
AC=7cm and CB=21
Step-by-step explanation:
1 to 3 ratio means you can just divide the total by four and mutiply by the ratio
28/4=7
7 x 1 = 7 cm
7 x 3 = 21 cm
and check your answer by addi gthe answer together, they should equal the total length of the line
21 + 7 = 28
Answer:75
90-15=75
