Remember that exponentioal rule
x^m times x^n=x^(m+n)
therefor
7^4 times 7^-6=7^(4-6)=7^(-2)
remember the other rule
x^-m=1/(x^m) so
7^-2=1/(7^2)=1/49

It is said the blue card is a rectangle, so you don’t have to minus the inside rectangle. :)
Answer: 
Step-by-step explanation:
Given : An equation relating packets to bytes of information : 
where<em> p</em> represents the number of packets and <em>b</em> represents the number of bytes of information.
1 byte = 8 bits
Let x= Number of bits such that 1 b = 8x
Put b = 8x in given equation , we get
Divide both sides by 8 , we get
Hence, the equation represent the relationship between the number of packets and the number of bits :
Answer:
1,115 mL
Step-by-step explanation:
The original amount of OJ is what we're trying to find, so that will be our variable, x. Now, keep in mind the order of events to write the correct equation. We started with the x amount of OJ, then 240 mL was taken away, to leave us with 875 mL. So, x - 240 = 875. Then we solve this by adding 240 to both sides to get the x alone. This gives us x=1,115 mL!
