Solve for m: 5m + 12 = -18." MCQ: A) m = -6 B) m = -6.4 C) m = 6 D) m = 6.4 . How would you write, 'Seven more than twice the value of a number, x, is equivalent to six,' in math terms?" MCQ: A) 7x = 6 B) 2x + 7 = 6 C) 2x - 7 = 6 D) 2x = 7 + 6

Answer :

Final answer:

In the equation 5m + 12 = -18, m equals -6. The English statement 'Seven more than twice the value of a number, x, is equivalent to six' translates into the math equation 2x + 7 =6.

Explanation:

To solve for m in the equation 5m + 12 = -18, you first need to subtract 12 from both sides in order to isolate the term with the variable. This gives you 5m = -30. Then, to completely isolate the variable m, you would divide both sides by 5, giving you m = -6. So, the answer is option A) m = -6.

The statement 'Seven more than twice the value of a number, x, is equivalent to six' in math terms is best translated to the equation 2x + 7 = 6. This equation represents twice a number (2x) plus seven equals six. The best match in your MCQ options is B) 2x + 7 = 6.
