Answer 1

Here are the mathematical expressions for converting stories into mathematical expressions.

Step-by-step explanation:

A. Multiply a number by 7: To convert this into a mathematical expression, you would use the equation 7x, where x represents the number.

B. Add 14 to a number: The mathematical expression for this would be x + 14 where x represents the number.

C. Subtract a number from 12: The mathematical expression would be 12 - x where x represents the number.

D. Subtract 6 from a number: The expression is x - 6 where x represents the number.

E. Divide a number by -3: The expression is x / -3 where x represents the number.

F. Divide -8 by a number: The expression is -8 / x where x represents the number.

G. Multiply a number by 4 then add 3: The expression is 4x + 3 where x represents the number.

H. Multiply a number by 8 then add 11: The expression is 8x + 11 where x represents the number.

I. Subtract 4 from a number then multiply by 6: The expression is (x - 4) * 6 where x represents the number.

J. Add -1 to a number, then divide by 3: The expression is (x - 1) / 3 where x represents the number.

K. Divide a number by 2 then subtract 13: The expression is (x / 2) - 13 where x represents the number.
