A super deadly train of bacteria is causing the zombie population to double every 2 days. currently, there are 25 zombies. after how many days will there be 25,600 zombies

25+25(2)+50(2)+100(2)+200(2)+400(2)+800(2)+1,600(2)+3,200(2)+6,400(2)=25,575 so after 18 days there will be 25,575 zombies :)

A(3x-8)=b-18x
what is a value?
what is b value?

We have that
a*(3x-8)=b-18x
3ax-8a=18x+b
The only way for this to happen (non-trivially) is if the coefficients of x are equal, and the constant terms are equal
so
3ax=18x-----> 3a=18--------> a=6
-8a=b---------> b=-8*6-------> b=-48

a=6
b=-48

The answer is 7xy , all you had to do was divide the number and then add the like  terms

Evaluate.

17 + 330 • 20 ÷ ÷ 2 – 14

36

Step-by-step explanation:

Simplify the following:

17 + 330×20/10^2×1/2 - 14

20/10^2×1/2 = 20/(10^2×2):

17 + 330×20/(10^2×2) - 14

330×20/(10^2×2) = (330×20)/(10^2×2):

17 + (330×20)/(10^2×2) - 14

20/100 = 20/(20×5) = 1/5:

17 + 165/5 - 14

The gcd of 165 and 5 is 5, so 165/5 = (5×33)/(5×1) = 5/5×33 = 33:

X+3y=3
2x-4y=6

solve the equations

Subtract the second equation from double the first equation:

2x+6y-2x-(-4y)=0

10y=0

Therefore, y=0.  Substituting this into the first equation, we see that:

x+3(0)=3

x=3

Therefore, x=3.  The solution to this system is x=3, y=0, or (3, 0).
So divide the second equation by 2
x-2y=3
the first equation is
x+3y=3
subsitute
3=3 so therefor
x-2y=x+3y
subtract x from both sides
-2y=3y

0=5y
ofviously y=0 so subsitute
x-2y=3
x-(2)0=3
x-0=3
x=3

x=3
y=0
