answer is D. last choice
2)
= 7x - 35 + 3x - 9
------------------------
(x - 3)(x-5)
= 10x - 44
--------------------
(x - 3)(x-5)
answer is B.
Answer:
x = 13°
Step-by-step explanation:
Check the diagram attached below to see how the angles labelled A and B, which are interior angles of the triangle where x is found.
Let's find the measure of angle A and angle B.
m<A = 85° (vertical angles are congruent)
m<B = 180° - 98° = 82° (corresponding angles/supplementary angles)
Thus:
x + A + B = 180° (sum of interior angles of a ∆)
x + 85° + 82° = 180° (substitution)
x + 167 = 180
x = 180 - 167 (Subtraction property of equality)
x = 13°
Answer:
3 male teachers didn't have sugar
Step-by-step explanation:
total number of male teachers = 3/5 x 20 = 12
3/4 of teachers have sugar, which is 15
3/5 of 15 = 9 (number of males who had sugar)
total number of males (12) minus number who had sugar (9) equals number of males who didn't have sugar (3)
