4 can be written as 4.00 in decimal form. 1/4 can be written as 0.25 in decimal form. When changing a decimal into a percent, you move the decimal to the right two times. If we move the decimal point in 4.00 twice we get 400. If we move the decimal point in 0.25 twice we get 25. If we add 400 and 25 together, we get 425. Therefore, the answer is 425%. Hope this helped! :)
x + y = 120° (given) x = y - 12 Then, y + y - 12 = 120° (y + y) - 12 = 120° 2y - 12 = 120° 2y = 120 + 12 = 132° y = 132/2 = 66° x = y - 12 = 66 - 12 = 54° There you go :)
