Answer:
4
Step-by-step explanation:
5(x + 1) -x = 17 Distribute the 5
5x + 5 - x = 17 Combine like terms
4x + 5 = 17 Subtract 5 from both sides
4x = 12 Divide both sides by 4
x = 3
Three is the smaller integer and 4 is the greater integer.

This is equal to...

We want "x" so we need to isolate it using laws of exponents...

because 
because ![x^{a/b}=\sqrt[b]{x^{a}}](https://tex.z-dn.net/?f=x%5E%7Ba%2Fb%7D%3D%5Csqrt%5Bb%5D%7Bx%5E%7Ba%7D%7D)
x = 4
answer: B
An aritmetic sequence is like this

where a1=first term and d=common difference
geometric is

where a1=first term and r=common ratio
can it be both aritmetic and geometric
hmm, that means that the starting terms should be the same
therfor we need to solve

what values of d and r make all natural numbers of n true?
are there values that make all natural numbers for n true?
when n=1, then d(1-1)=0 and r^(1-1)=1, so already they are not equal
the answer is no, a sequence cannot be both aritmetic and geometric
Answer:
It takes them 7minutes to finish 50env
Step-by-step explanation:
We know that jerry can stuff 7 in 2min and tom can do 4 per min, so 8 for every 2min.
So 8+7=15env for every 2min 7.5/min
15+15=30+15=45
50=15x/2 50*2=15x 100=15x 100/15=x x=6.67 then rounded it to 7min
