Step-by-step explanation:

Start

Percentage with tusks = 122/125 = 97.6%

Percentage without tusks = 3/125 = 2.4%

End

Percentage with tusks = 327/375 = 87.2%

Percentage without tusks = 48/375 = 12.8%

How do you solve an absolute value equation?

Mkey [24]

The distance between two real numbers $x,y$ is the absolute value of their difference, $|x-y|$ . So the statement "all $x$ that are 1/4 away from -6" is captured in the equation

$|x-(-6)|=\dfrac14$

$|x+6|=\dfrac14$

To solve, you can use the definition of absolute value: if $x$ is not negative, then $|x|=x$ ; otherwise, $|x|=-x$ .

So there are two cases to consider:

1. Suppose $x+6\ge0$ . Then $|x+6|=x+6$ , and the equation reduces to

$x+6=\dfrac14\implies x=-\dfrac{23}4$

2. Suppose $x+6$ . Then $|x+6|=-(x+6)=-x-6$ and

$-x-6=\dfrac14\implies x=-\dfrac{25}4$

$-6=-\dfrac{24}4$ , so the two solutions we found are correct because both $-\dfrac{23}4$ and $-\dfrac{25}4$ are indeed 1/4 away from -6.

- - -

For the question regarding inequality, you know that the absolute value must return a non-negative number. In other words, there is no $x$ such that $|x|$ .

Simplify the expression by combining like terms. Then,

Inessa [10]

Answer:

-14

Step-by-step explanation:

The like terms in this equation is y^2 and -7y^2 so combining the two the equation becomes:

xy-6y^2

Then we substitute the values in:

5×2-6×2^2 = -14

The perimeter of a triangle is 42 centimeters. The longest side is 2 centimeters less than 3 times the shortest side and the pot

Mariulka [41]

Answer:

7 cm, 16 cm, 19 cm

Step-by-step explanation:

Let s represent the length of the shortest side in cm. The longest side is 3s-2, and the other side is 2s+2. The perimeter is the sum of the side lengths.

P = s + (3s -2) +(2s +2)

42 = 6s . . . . . simplify, use the given value of perimeter

7 = s . . . . . . . divide by 6

2s+2 = 16

3s -2 = 19

The side lengths are 7 cm, 16 cm, and 19 cm.
