Answer:
Sum he wasn't suupposed to be doing....... ;-;
Step-by-step explanation:
Answer:
With the rule: d(n) = d(n-1) x (-5), we have:
d(1) = 8
d(2) = d(1)x(-5) = 8x(-5) =-40
d(3) =d(2)x(-5) = -40x-5 =200
Other way:
d(n) = d(n-1) x (-5) => d(n) = d(1)x(-5)^(n-1)
d(3) = d(1)x5^(3-1) =8x5^2=8x25 =200
Answer: b+15 = g
Step-by-step explanation:
g = girls
b= boys
t= total students
If you wanted to solve it a different way you would do this:
(b + 15) + b = t
So u have to rearrange to find x.
First u multiply by - 2 to get rid of the fraction bit
This leaves u with - 46>/x-49
Now u have to get x on its own which means you have to get rid of - 49 and to do this the opposite of - 49 is +49, so you would ADD 49
This gives you 3>/x
And the number line which represents this is B.
