Solve: 12 - 2x = -2(y - x)
Steps:
1. Expand -2(y - x): -2y + 2x
12 - 2x = -2y + 2x
2. Then subtract 12 from both sides
12 - 12 - 2x = -2y + 2x - 12
3. Simplify,
-2x = -2y + 2x - 12
4. Then, subtract 2x from both sides
-2x - 2x = -2y + 2x - 2x - 12
5. Simplify,
-4x = -2y - 12
6. Then, divide both sides by -4
-4x/-4 = -2y/-4 - 12/-4
7. Simplify,
x = 1/2y + 3 <======= <em>Answer</em>

Answer: 34.2 pounds
Step-by-step explanation:
First, convert 15 4/5 into an improper fraction. You should get 79/5. Then, convert 50 into a fraction that has a denominator of 5. Right now, 50= 50/1 so just multiply the top and bottom by 5 to make it 250/5. Then, subtract 79/5 from 250/5. You should get 171/5. Lastly, simplify. You should get 34.2 pounds as your final answer. Hope this helps!
Answer:
I think the answer is 8 rounding tho would be 10
Step-by-step explanation:
Answer/Step-by-step explanation:
Given:
C = right angle = 90°
BC = a = ?
AB = c = 12
AC = b = 9
Required:
a, <A, and <B
Solution:
✔️Find a using Pythagorean Theorem:
a = √(c² - b²)
a = √12² - 9²) = √63
a = 7.93725393 = 8 (nearest whole number)
✔️Find A by applying trigonometric ratio:
Thus,
Reference angle = A
Hypotenuse = 12
Adjacent = 9
Therefore,
m<A = 41° (nearest whole number)
✔️Find B:
m<B = 180 - (90 + 41) (sum of interior angles of triangle)
m<B = 49°
