To solve, you make a systems of equation:
x+(x+3)=25, the x representing the number of pigs. Since there is no multiplication and following the order of operations, you add the x’s to get 2x+3=25. Then, you subtract 3 from both sides to get 2x=22, then divide by 2 on both sides to isolate the variable. Therefore, x=11 and Mary is taking care of 11 pigs.
Answer:
Cos 2x+sin x = cos x cos x - sin x sin x + sin x
Step-by-step explanation:
Cos 2x+sin x
use Trigonometric identities.
cos (2x) = cos (x + x) = cos x cos x - sin x sin x
Cos 2x+sin x = cos x cos x - sin x sin x + sin x
Answer:
second one Step-by-step explanation:
The common factors of 24 and 48 are 1, 2, 3, 4, 6, 8, 12, and 24.
Factors are the numbers that can be multiplied with another number, to equal the product stated. Common factors are the factors that both stated products have.
Factors of 24: 1, 2, 3, 4, 6, 8, 12, and 24.
Factors of 48: 1, 2, 3, 4, 6, 8, 12, 16, 24, and 48.
Finding all the shared factors, will give you a final answer of 1, 2, 3, 4, 6, 8, 12, and 24.
I hope this helps!
