Write the population of florida in expanded form using exponents

floride population = 18,801,310

Expanded form ;

1x10^{7} + 8x10^{6} + 8x10^{5} + 0x10^{4} + 1x10^{3} + 3x10^{2} + 1x10^{1} + 0x10^{0}      

i will pick c put check it over to be sure

step-by-step explanation:

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
