. {5.NBT. A.3.A} Write the number 78.516 in expanded form. * 7 x 100 + 8 x 10 + 5 x (1/10) + 1 x (1/100) + 6 x (1/1,000)
7 x 10 + 8 x 1 + 1 x (1/100) + 6 x (1/1,000)
7 x 10 + 8 x 1 + 5 x (1/10) + 1 x (1/100) + 6 x (1/1,000)

Byou start by adding them all and setting them equal to 180 since that is half of the total degrees in a circle.(2x+8) + (3x-14) + (3x-14) = 1808x-20 = 1808x = 200x = 25

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
