Answer:
x=-19
Step-by-step explanation:
x-5=2x+14
-x=19
x=-19
To find out the result, we have to divide 365 days by 28 days:
365 / 28 = 13,03571428571429
So we can see it's 13 lunar months with something extra. To find that something extra we can multiply 28 by 13 and then substract the result from 365:
365 - (13 * 28) =
= 365 - 364 =
= 1
So there are 13 lunar months and one day.
The equation of this problem is y=mx+b, so this problem is y=1/2x+3

Answer:
2. chord theorem; t = 10.5
3. chord theorem; x = 5
Step-by-step explanation:
For both of these problems, the relevant theorem is the "intersecting chord theorem", also referred to as the "chord theorem." It tells you the product of the lengths of the parts of one chord is equal to the product of the lengths of the parts of the other chord.
2. 20t = 10·21
t = 210/20 . . . . divide by 20
t = 10.5 . . . . . . . simplify

3. 10(x +4) = 15(x +1)
10x +40 = 15x +15 . . . . . eliminate parentheses
25 = 5x . . . . . . . . . . . . . subtract 10x+15
5 = x . . . . . . . divide by 5
Answer:
7
Step-by-step explanation:
5 1/4= 5.25
3/4=.75
5.25/0.75=7
