Answer:

The sum of the exterior angles of a polygon is always 360°.

Therefore,

x+2x+3x+5x+9x=360

20x=360

Divide both sides by 20:

\frac{20x}{20}=\frac{360}{20}

x=18

How many gallons of a 12% salt solution should a biologist add to 5 gallons of a 15% salt solution to get a 14% solution?
Zarrin [17]

The volume of the 12% salt solution to be added is; 2.5 gallons.

<h3>Ratio and Proportion of Volume</h3>

Let the volume of 12% required be x and the new volume of the mixture be (x+5).

On this note, it follows that;

  • 12x + 15(5) = 14(5+x)

  • 12x + 75 = 70 + 14x.

Hence, -2x = -5

Divide both side by -2;

  • x = -5/-2

x = 2.5 gallons.

28/29 and 30 plz short explanation thanks
zzz [600]

Integers are numbers like ...-3, -2, -1, 0, 1, 2, 3... and so on. So, according to this definition, let's solve this problem:


28. We know that the product of three integers is -3. So, the statement states that we have three factor, so:


a.b.c = -3


The possible values of the factors are:

  • Factors are: 3, 1 and -1 in which case:

(3)(1)(-1) = -3

  • Factors are: -3, 1 and 1 in which case:

(-3)(1)(1) = -3


29. In this problem we know two nonzero integers, that is, they cannot be equal to zero. Thus, they must have different sign, that is, one of them must be positive and the other negative. For instance:


  • -9 and 2

(-9)(2) = -18, So -18 is less than -9 and 2


Another example:


  • 1 and -8

(1)(-8) = -8, So -8 is equal to -8 and -8 is less than 1.


30. The sign of the product of two integers with the same sign is positive, that is:


(+)(+) = (+) and

(-)(-) = (+)


So, the sign of the product of three integers with the same sign are two options:

  • <u>Option 1.</u> The three integers are positive in which case:

(+)(+)(+) = (+), So the sign of the product is positive


  • <u>Option 2.</u> The three integers are negative in which case:

(-)(-)(-) = (-), So the sign of the product is negative.


This option two gives us that result because:


(-)(-) = (+) and (+)(-) = (-)
