Alocal college states it has a 14: 1 student to teacher ratio. how many teachers would you expect to find if there are 42,000 students enrolled in the college? a. 3,000 b. 200 c. 2,700 d. 5,000

What is the missing step in this proof ?

It says factor each expression 49x-28?

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.
