Answer:
D supplementary angles
Step-by-step explanation:
<span>2x^3+3x^2-30x+7/x-3 divide</span>
500×((1+0.06÷12)^(12×25)−1)÷(0.06÷12)
=346,496.98
2x + 3y = 630
x + y = 245 then you want to get rid of x so in the second equation × by -2 and get -2x -2y =-490 subtract this equation from the first to get y=$140 substitute 140 in for y and get x= $105 and 2x=210 and 3y=420 210 +420=630
