The distributive property: a(b - c) = ab - ac
27 - 18r = 9·3 - 9·2r = 9(3 - 2r)
Answer:
First quadrant
Step-by-step explanation:
cosθ > 0 in first/ fourth quadrants
sinθ > 0 in the first/ second quadrants
sinθ and cosθ are both > 0 in the first quadrant
Then θ lies in the first quadrant
Answer:
81
Step-by-step explanation:
angles of a triangle always equal 180, so 41 +58=99, so subtract that from 180 and the remaining angle is 81
Answer:
First of all this question makes no complate sense if this was in real life. But the answer is: Allen is 23 years old and Jim woukd be 12 1/2 years old.
Step-by-step explanation:
Because 20+3=23. That's because it said in 3 years. Tthen we divide by 2 to find Jim's age. That's because it said that in three years, Allen would be twice as old as Jim.
D = 900t
because if you want to simplify t (2 hours) into one then you divide 1800 by 2 and that gives you the constant of proportionality (slope) of 900. Using this information you can write the expression d = 900t.
