Answer:

276°

Step-by-step explanation:

In the figure attached, circle D is shown.

arc BA + arc AC + arc CB = 360°

(7n + 12) + (13n - 16) + 6n = 360

26n - 4 = 360

n = (360 + 4)/26 = 14°

arc BAC = arc BA + arc AC

arc BAC = (7n + 12) + (13n - 16)

arc BAC = 20n - 4

arc BAC = 20(14) - 4 = 276°

Answer:

The answer is 276 degrees. I checked on Khan Academy. The reason 84 degrees is NOT the answer is because that would be the minor arc, not the major arc.

they said this is math but it looks like ELA

Answers

Final answer:

The clearest translation of the equation 4 + 6z = 12 is 'Four plus six times a number is twelve.' Solving the equation gives the value of 'z' as 4/3 or approximately 1.333.

Explanation:

The clearest translation of the equation 4 + 6z = 12 is: Four plus six times a number is twelve.

The equation can be solved to find the value of 'z', which represents the unknown number. First, subtract 4 from both sides of the equation: 6z = 8. Then, divide both sides by 6: z = 8/6 or 4/3. So, the unknown number is 4/3 or approximately 1.333.

Final answer:

The phrase 'Four, plus six times a number, is twelve' best translates the mathematical expression 4 + 6z = 12. This phrase accurately demonstrates the order of operations and includes each element of the mathematical equation.

Explanation:

The statement 'Four, plus six times a number, is twelve' is the clearest translation of the algebraic equation 4 + 6z = 12. The term 'six times a number' signifies multiplication with an unknown (z in this case). The first part of the sentence 'Four, plus' stands for addition of 4 to the result of that multiplication. Altogether, 'Four, plus six times a number, is twelve' conveys that 4, added to the result of 6 multiplied by some number (z), equals 12.
