Answer:
x = -14
Step-by-step explanation:
-1/2x - 3 = 4
-1/2 * x = 4+3
-1/2 * x = 7
x = 7/(-1/2)
x = -14
Good luck with your schoolwork/homework!

Apologies in advance for wrong answers or bad explanation.
6j+

n=134

you multiply this by 18
6j+18n=558
6j+1/3*n=134
___________(-)
53n/3=424 => 53n=1272 => n=24
You put n in the first equation:
6j+8=134
6j=126 => j=21
Final answer: Nathan has 24 books and Jason 21.
Answer:
(-3.5,1)
Step-by-step explanation:
There are 7 boxes between A and B. So I figure if you take 3/4 of 7 is about 5.
The answer i think is the rate
Remember that the general decay equation is:

where

is the amount after a time


is the initial amount

is the the decay percent in decimal form
The first ting we are going to do is find

by dividing our <span>decay rate of 25% by 100%: </span>

.
We also know from our problem that

. Lets replace

and

in our formula:


We know now that our decay rate is 0.75, and since 0.75<1, we can conclude that
this situation represents exponential decay.
Now, to find the initial amount, we are going to solve our equation for

:


Notice that

will depend on the number of ours
