25 = 5*5
405 = 81*5
therefore, 25/405 = (5*5)/(81*5)=5/81

Substitute x = 3 in any given equations. I will do in y = - x + 1

Therefore the answer is (3,-2)
(12 times/16 seconds) = (x times/60 seconds)
x times = (12 times/16 seconds)*(60 seconds)
<span>x = 45 times</span>

Answer:
Step-by-step explanation:
64
because the small triangle at the top is isoscel and has the base angles BDE and BED = (180 -48)/2 =66
angle BDE is congruent to DAC = 66, because 2 || BE and AC are cut by transversal BA
angle ADC = 180 -50 -66 = 64
