Answer:
1/38^8
Step-by-step explanation:
3.8 times 10 is 38
so it would be 38 to the power of -8 ( 38^-8 )
then you simplify
you have to rewrite the negative power
( you can't have negative power as numerator )

so you put it a part of the denominator
which switches the sign

hope this helps
Answer:
30 seats
Step-by-step explanation:
To answer this question, we will be assigning values for both rows and seats.
R = Rows
S = Seats
Remember that rs = 600
r = s - 10, plug this equation into rs = 600, and factor it:
s(s-10) = 600
s^2-10s-600 = 0
(x-30)(x+20) = 0
There are 30 seats in the row. To determine which one is your answer, your answer MUST be positive because it is impossible to have negative seats. (x-30) is 30, which is the positive value found when factoring.
Answer:
16y-4x
Step-by-step explanation:
first distribute the negative to the numbers in parentheses
13y-5x+3y+x
then combine like terms
13y+3y=16y
-5x+x=-4x
16y-4x
A. you plug in to a calculator, which will give 1840.986 so you need to round up to 1840.99. if you truncate it to .98 then he won't reach 2000 in 3 years
b. for this one if you look at the equation given to find the principle it is principle = result (1+rate) ^ -time
if you re arrange this you get result=principle (1+rate)^time
so result = 1840.99(1.028)^5
= 2113.57
