We have similar triangles so
12/x = (12+78)/(x+13)
We can skip some algebra by doing the ratio on the pieces. We'll show it works at the end.
12/x = 78/13
x = 12(13)/78 = 2
We check
12/2 = 6
(12+78)/(2+13) = 90/15 = 6, good
Answer: x=2
Let us solve the given equations.
Consider the equation 1,
So, x = 7 and -7
Consider the equation 2,
Consider the equation 3,
Consider the equation 4,
So,
Consider the equation 5,
So, x = 5i and -5i
Consider the equation 6,
Since, both are prime numbers.
So,
Answer:
19
Step-by-step explanation:
Is he stop every 1/4 mile you get 19
There are 4 1/4 miles in every mile. 4x4(Equation of total 1/4th's in 4 miles) is 16. Add 3 more 1/4th's to get 19
Hope this helps!
F-1(n)3*-2 is the recursive formula
