Answer:

(-\frac{7}{6} )

Step-by-step explanation:

From the question the emerald was located at a depth which is between -1/2 and -1 2/3 meters

This statement can be written as

(-1\frac{2}{3}) -(-\frac{1}{2} )

To get the depth, you find the depth of the emerald location, you find difference between the two mentioned depths

-(1\frac{2}{3} )-(-\frac{1}{2} )\\\\

Change first term to improper fraction

=-(\frac{5}{3} )-(-\frac{1}{2} )\\\\

Find the LCM to solve the operation the involves the fractions.The Least common multiple here is 6 i.e 3*2

=(-\frac{5}{3} )-(-\frac{1}{2})\\

=\frac{-5}{3} +\frac{1}{2} =\frac{-10+3}{6} =\frac{-7}{6}

The number that could represent the depth at which the emerald was located is

=\frac{-7}{6}

Can someone please help me with this
omeli [17]

Answers:

  • x = 3
  • CD = 21
  • DE = 16
  • CE = 21

=============================================================

Explanation:

The congruent base angles are D and E. Opposite those angles are the sides CE and CD. These opposite sides are the same length.

CE = CD

16x-27 = 4x+9

16x-4x = 9+27

12x = 36

x = 36/12

x = 3

This x value then leads to the following:

  • CD = 4x+9 = 4*3+9 = 12+9 = 21
  • DE = 7x-5 = 7*3-5 = 21-5 = 16
  • CE = 16x-27 = 16*3-27 = 48-27 = 21

We see that CD and CE are both 21 units long, which helps confirm we have the correct x value.
