Answer:
x = 17
Step-by-step explanation:
3(x-12)=15
->
x-12+12=5+12
Let the length of the first piece be x inches. Then:-
x + 2x + 4x + 3 = 38
7x = 38 - 3
x = 35/7 = 5 inches
Answer: the 3 pieces have lengths 5, 10 and 23 inches.

this is your answer. thanks!!
Answer:
Please check the explanation.
Step-by-step explanation:
Given
- The location of Point A on the number line = -13.4
- The location of Point B on the number line = 14
- The location of Point C on the number line = 19.9
The location of Point C on the number line = 19.9
Thus, the distance or length between B and C can be calculated by subtracting the point B units from point C units.
BC = 19.9 - 14
= 5.9 units
Therefore,
BC = 5.9 units
Also, the distance or length between C and A can be calculated by subtracting the point C units from point A units.
CA = -13.4-19.9
= -33.3 units
Therefore,
CA = -33.3 units
As the length or distance can not be negative, hence
CA = 33.3 units
