Answer:
1/12
Step-by-step explanation:
When you add or subtract fractions, you need a common denominator.
Let's use the least common denominator of 12, 6, and 3.
Since 12 is a multiple of 6 and 3, the LCD is 12.
7/12 - 1/6 - 1/3 = 7/12 - 2/12 - 4/12 = 5/12 - 4/12 = 1/12
He is at -18 feet because you do -28 - 5 which equals -33 after that you do -33 + 15
3 AND 18, the only factors
Answer: A
Step-by-step explanation: 107 is larger than 30
Answer:
m∠A = 20°
Step-by-step explanation:
Given that the sum of the angles of any triangle is 180°, adding the expressions of each angle and setting them equal to 180° will give the value of 'x' and allow you to evaluate the angles.
2x + 5x + 11x = 180
18x = 180
18x/18 = 180/18 or x = 10
m∠A = 2x or 2(10) = 20°
m∠B = 5x or 5(10) = 50°
m∠C = 11x or 11(10) = 110°
Out of the choices given, the only one that is true is that m∠A = 20°.
