There are 13 students in Sara's class. I did this by using 8 = 3/5x, x being the total number of students. The answer is 13.33334 but you cant have half a student so it rounds down to 13.
also number 4 can be any positive number. This is because if you take one fourth of a negative number it will be more than if you doubled it. for example 1/4 of -4 is -1 which is more than -4 doubled which is -8

Q(-2, 3) and P (2, 1)<br> Find the length of the segment. Simplify each radical,if possible
Montano1993 [528]

9514 1404 393

Answer:

  2√5

Step-by-step explanation:

The distance formula is useful for this.

  d = √((x2 -x1)² +(y2 -y1)²)

  d = √((2 -(-2))² +(1 -3)²) = √(4² +(-2)²) = √20

  d = 2√5

The length of segment PQ is 2√5.

What is the measure of x
mixer [17]

Answer:

x=76 degrees

Step-by-step explanation:

< dij + < jih = 180   straight line

< dij + 107 = 180

subtract 107 from each side

< dij = 73


<jdi + < dij + <idj = 180  triangle

31 + 73 + < idj = 180

combine like terms

104+ < idj = 180

subtract 104 from each side

< idj = 76

<idj = < ajf   vertical angles

76 < ajf

<ajf = x

x=76 degrees
