The cost to mail a letter is a base charge of $0.42 plus $0.17 for each once. Write a equation that could be used to find how ounces a letter that costs $0.93 weighs. (Let x represent the number of ounces)

A) 0.59x = 0.93

B) 0.42x + 0.17 = 0.93

C) 0.59 = 0.93x

D) 0.42 + 0.17x = 0.93

PLEASE HELP

D

Step-by-step explanation:

0.93 - 0.42 = 0.51

0.51 / 0.17 = 3

3 ounces and the answer is D

-24,

Step-by-step explanation:

An opposite number or additive inverse of any number (n) is a number which, if added to n, results in 0. The opposite number for n is written as −n.

For 24, this is -24.

A multiplicative inverse or reciprocal for a number n, is a number which when multiplied by n, their product is 1. To find the multiplicative inverse of a real number, just divide 1 by that number.  The reciprocal for n is written as or .

For 24, this is .
