x=-6 because multiply x/3 by its reciprocal which is 3/x and do the same to the other part of the equation which is -2, and -2*3=-6. If you check your work, and use -6 as x, then -6/3=-2 and that is correct

Answer:
Juan has to work at least 21 weeks.
Step-by-step explanation:
Juan earns $3 a day, then he earns $21 per week.
Let x be the number of weeks Juan works. He will earn $21x in x weeks.
Juan has saved $213,
He earns $21x,
Juan's total earnings are $213+$21x.
He needs to save at least $654, so
Juan has to work at least 21 weeks.
Increase from 491,675 in the year 2000 to 782,341 in 2010.
A. The solution for the exponential growth rate, B. Write the exponential growth function and C What should the population be in 2016.
A. 782341/491675 = 1.5911750648294096710225250419484, or a growth rate of 59% over 10 years. So:(1+k)^10 = 1.5911750648294096710225250419484ln (1+k)^10 = ln 1.591175064829409671022525041948410 ln(1+k) = ln 1.5911750648294096710225250419484ln(1+k) = ln 1.5911750648294096710225250419484/10 = 0.04644727777645335179835425806392e^0.04644727777645335179835425806392 = 1+kk = 1.0475428488243655419718940009655, or 4.75428488243655419718940009655% growth rate per year.
B. Population year t = 491675 x (1.0475)^(t-2000)
C. Population in 2016 = 491675 x (1.0475)^16 = 1033100.64 people
Answer:
Step-by-step explanation:
x+5y=-27
-2x-5y=24
If the signs are the same u minus if they are different u add
So they are different were gonna add
x+5y=-27
-2x-5y=24
-1=-3
You cant divide it further x=-3
Next were gonna subsitute in any equation
x(-3)+5y=-27
-3+5y=-27
+3 to -27
-7+3=-24
5y=24
24/5=4.8 y=4.8
I hope this helps.
