Answer:
x = 8.33 meters
Step-by-step explanation:
what is x in meters?
The line segment addition postulates states that given two endpoints A and C with a point B placed between point A and point C, then the points A, B and C meets the equation:
AB + BC = AC
Since point P is between point A and point C. Hence the following equation holds:
AC = AP + PC
Substituting values:
25 = 3x - 8 + 8
3x = 25
x = 25/3
x = 8.33 meters
AP = 3x - 8 = 3(8.33) - 8 = 17 meters
That means its another way scientist use this method to easly use large numbers or very small numbers for example 0.0000000056, they make it like this 5.6*10 to the -9 power
Answer:
15
Step-by-step explanation:
123=x+x+12+(x+12)*3
123=5x+48
75=5x
15=x
Answer:
803.4
Step-by-step explanation:
4/5 - 5/10 =
4/5 = 8/10
5/10 = 5/10
8/10 - 5/10 = 3/10 ( lowest form)
how I got the denominator is 10 and 5 can go into each other. so 5 x 2 = 10 so, 2 x 4 = 8. 5/10 stays the same. then subtract.
