What expression is equivalent to -1/4 -5/3
-1/4 + (-5/3) or -1/4+5/3

First option:

Step-by-step explanation:

 By definition, Equivalent expressions have the same value, even though they are written in different forms.

For this exercise it is important to remember the multiplication of signs:

Given the following expression:

Since:

You know that:

Therefore, knowing this, you can determine that the given expression can be written in the following form:

The equivalent expression is the one shown in the first option.

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
