Which of the following is equivalent to –(–5.25) ? 5 5.25 –5 –5.25<br>please answer fast​
Marina86 [1]

Answer:

The equivalent to -(-5.25) = 5.25

Step-by-step explanation:

Given

-(-5.25)

We need to determine the equivalent to -(-5.25)

some of the sign rules are:

+(+) = +      

−(−) = +

+(−) = -

−(+) = -

Thus,

-(-5.25)

Applying the rule: -a(-a) = a

=5.25

Therefore, the equivalent to -(-5.25) = 5.25

Find the domain and range of the relation: (-8,8),(-8,7),(-8,6),(-8,5). Then determine whether the relation is a function.
Andrej [43]
The domain is {-8}
The range is {5,6,7,8}
The relation is not a function as the domain value -8 maps to multiple values. All domain values in a relation needs to map to exactly one range value for it be a function.

The sum of the measures of the angles of a triangle is 180. The sum of the measures of the second and third angles is five times
mafiozo [28]
  • Answer:

<em>a = 30°</em>

<em>b = 70°</em>

<em>c = 80°</em>

  • Step-by-step explanation:

<em>Hi there ! </em>

<em />

<em>a ; b ; c = angles</em>

<em>a + b + c = 180°</em>

<em>b + c = 5a</em>

<em><u>replace (b + c)</u></em>

<em>a + (b + c) = 180</em>

<em>a + 5a = 180</em>

<em>6a = 180</em>

<em>a = 30°</em>

<em />

<em>b + c = 180 - a</em>

<em>b + c = 150</em>

<em>c = b + 10</em>

<em><u>replace c</u></em>

<em>b + (b + 10) = 150</em>

<em>2b = 150 - 10</em>

<em>2b = 140</em>

<em>b = 70°</em>

<em>c = b + 10</em>

<em>c = 80°</em>

<em>Good luck !</em>
