15. n - 6 = 21......add 6 to both sides
    n = 21 + 6
    n = 27

16. p + 1 3/4 = 4 5/8...turn mixed numbers to improper fractions
     p + 7/4 = 37/8....there is 2 ways to continue from here...I will show u            both

(1) p + 7/4 = 37/8....multiply everything by common denominator of 8, this gets rid of the fractions.
8p + 14 = 37 (result of multiplying by 8)
8p = 37 - 14
8p = 23
p = 23/8

(2) p + 7/4 = 37/8...subtract 7/4 from both sides
      p = 37/8 - 7/4...common denominator is 8
      p = 37/8 - 14/8
      p = 23/8

either way u use, u will arrive at the same answer

Thank you to whoever helps!
shepuryov [24]

Answer:

  • M
  • 90°

Step-by-step explanation:

The segment joining an original point with its rotated image forms a chord of the circle of rotation containing those two points. The center of the circle is the center of rotation.

This means you can find the center of rotation by considering the perpendicular bisectors of the segments joining points with their images. Here, the only proposed center that is anywhere near the perpendicular bisector of DE is point M.

__

Segment AD is perpendicular to corresponding segment FE, so the angle of rotation is 90°. (We don't know which way (CW or CCW) unless we make an assumption about which is the original figure.)

28 in 21 in., 20 in.<br> Is this a right triangle?
ankoles [38]

Answer:

No, it is not a right triangle.

Step-by-step explanation:

The simplest way to determine is testing out the numbers with Pythagorian theorem.

If it complies with the theorem, it is a right triangle.

let's assume c = 28, b = 21, and a = 20

the longest side is the hypotenuse so side c (28 in) will be the hypotenuse.

According to the Pythagorian theorem, the square of the length of hypotenuse must equal to the sum of squares of other two sides.

check:

c^2 = 28^2 = 784

a^2 + b^2 = 21^2 + 20^2 = 841

because c^2 is not equal to a^2 + b^2, the triangle is not a right triangle.

Find the coordinates of the midpoint of the segment given its endpoints P(-3,-7) and Q(3,-5)
stellarik [79]

Answer:

Midpoint....; (0,-6)

Step-by-step explanation:

Midpoint of the segment

= [(sum of x-coordinates) ÷ 2] , [(sum of y-coordinates) ÷ 2]

Midpoint = [( 3 + (-3))÷ 2 , (-5 + (-7))÷ 2]

Midpoint = ( 0/2 , -12/2 )

Midpoint = (0,-6)

When adding √9 and -7, which type of number is the sum?
dezoksy [38]

We are given numbers √9 and -7.

Square root 9 is a perfect square.

Square root 9 = 3.

So, if we add square root 9 and -7, we would get

√9 + -7 = 3 -7 = -4.

So, we got a negative whole number.

<em>A negative or positive whole number is called an integer</em>.

So, it's an integer.

<h3>Therefore, correct option is D. Integer.</h3>
