Answer:
this is an x y coordinate plane, start with x and then move to y.
Answer:
1.) The answer is b = 6
2.) The answer is t = 10
Step-by-step explanation:
For the first equation in order to fin out the answer we do.....
b + 8 = 14
b + 8 - 8 = 14 - 8
b = 6
For the second question we do....
25 - t = 15
25 - t + t = 15 + t
25 = 15 + t
25 - 15 = 15 + t -15
10 = t
The number that presents 8/9 to the nearest percent is .89.
Here's a way to do it.
Let 4e +2 = 5n +1 . . . . . . for some integer n
Then e = (5n -1)/4 = n + (n -1)/4
We want (n-1)/4 to be an integer, so let it be integer m.
... m = (n -1)/4
... 4m = n -1
... 4m +1 = n
Substituting this into our expression for e gives
... e = (5(4m+1) -1)/4 = (20m +4)/4 = 5m +1
e = 5m+1 for any integer m
