Solve using augmented matrix methods. 16x_1+ 12x_2 = 4 -8x_1-6x_2 =-2 select the correct choice below and, if necessary, fill in the answer box to complete your choice. a. the unique solution is x, ad2(simplity your answer) the system has infinitely many solutions. the solution is x1 = and x2-t. (simplify your answer. type an expression using t as the variable. do not factor) b. c. there is no solution

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

there is no graph so i cant sorry

step-by-step explanation:

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076
