Answer:
Step-by-step explanation:
Sin A Cos B + Cos A Sin B = Sin (A +B)
Sin 10 cos 50 + Cos 10 Sin 50 = Sin (10 + 50) = Sin 60 = √3/2
Answer:
-4.33
Step-by-step explanation:
-26=6ₓ
6x = -26
x = -26/6
x = -4.33 or -13/3
Is it more to this question like numbers or something I don’t really understand
Answer:
Seth saved $90.
Step-by-step explanation:
1.Find out how much would be spent without buying the movie pass.
Multiply the amount of money that one would spend for each movie, by the number of movies one saw.
8 * 30 = 240
2.Find out the amount that was actually spent
Multiply the amount that was actually spent on each movie, by the number of movies that were seen. Then add the additional cost of the pass.
(4 * 30) + 30
= 120 + 30
= 150
3. Find the difference between the two values.
Subtract the amount that one was supposed to spend by the amount one did spend.
240 - 150
= 90
<span>(3a^2 - 2a + 4) - (a^2 - 3a + 7) = (distribute the negative sign)
3a^2 - 2a +4 - a^2 + 3a - 7 = (add like terms)
2a^2 + a - 3
So, the answer is A!
