You need to use all of them until you find the answer so lets fo this! a. (-10,-12) x=-10 y=-12 3x+2y=6 3*(-10)+2*(-12)=6 -30-24=6 -54=6 This is incorrect,now we try the othe options b.(10,12) x=10 y=12 3x+2y=6 3*10+2*12=6 30+24=6 54=6 This is incorrect then we try the other option c. (-10,12) x=-10 y=12 3x+2y=6 3*(-10)+2*12=6 -30+24=6 6=6 And this is the correct answer. So the answer is c. (-10,12)
Do 360 <span>÷ 24/100. Flip the fraction so that it is now 360 x 100/24. Make that 360 x 100/24. That is then 36000/24. Do the division and then you get 1500. </span>
