Which set of ratios could be used to determine if one triangle is a dilation of the other? O 3.6/3= 5.4/4.5= 6/5
O 3.6/3= 4.5/5.4= 6/5
O 3/3.6= 4.5/6= 5/5.4
O 3/4.5= 3.6/5.4= 5/6

50 will mark show all use the linear combination method to solve the system of equations. explain each step of your solution. if steps are not explained, you will not receive credit for that step. 2x+9y= -26 -3x-7y=13

The table below shows the approximate masses of a dust particle and a grain of pollen. dust particle 0.000000778 g grain of pollen 0.00000000155 g the mass of a dust particle can be estimated and written in the form a × 10^b, where a = 8 and b = the mass of a grain of pollen can be estimated and written in the form a × 10^b, where a = 2 and b = based on the estimates, the mass of a dust particle is approximately blank times larger than the mass of a grain of pollen.
