There are 100 elections in each pack there are 12 in each box how many electrons are in each box

Which shows the correct solution of the equation 1/2a+2/3b=50, when b=30?

Use the formulas a = x 2 – y 2, b = 2xy, c = x 2 + y 2 to answer this question. one leg of a right triangle has length 11 and all sides are whole numbers. find the lengths of the other two sides. the other leg = a0 and the hypotenuse = a1

What is the image of c for a 90° counterclockwise rotation about a? (3, 7) (-1, 3) (7, 3)
