The equation $y+4x=100$ represents your distance y (in meters) from the finish line x seconds after you begin your leg of a relay race. The equation $y+3.6x=94$ represents your opponent’s distance from the finish line. How far do you need to run until you catch up to your opponent?

Look at this pattern ; 1,4,9, number 10000 belongs in this pattern . what’s the place of this number?

If m∠abc = 70°, what is m∠abd? justify your reasoning.  using the addition property of equality, 40 + 70 = 110, so m∠abd = 110°.  using the subtraction property of equality, 70 − 30 = 40, so m∠abd = 30°.  using the angle addition postulate, 40 + m∠abd = 70. so, m∠abd = 30° using the subtraction property of equality.  using the angle addition postulate, 40 + 70 = m∠abd. so, m∠abd = 110° using the addition property of equality.
