Answer:

X=9

Step-by-step explanation:

<u><em>Rearrange terms</em></u>

(16−)+(4)=+2

(−+16)+(4)=+2

<u><em>Eliminate redundant parentheses</em></u>

(−+16)+4=+2

−+16+4=+2

<em><u>Add the numbers</u></em>

−+16+4=+2

−+20=+2

<em><u>Subtract 20  from both sides of the equation</u></em>

−+20=+2−+20

−20=+2−20

<em><u>Simplify</u></em>

−=−18

The perimeter of a △ABC equals 12 in. The midpoints of the sides M, N and K are connected consecutively. Find the perimeter of △
Zarrin [17]

Answer:

<em>Perimeter of ΔMNK is </em><em>6 in.</em>

Step-by-step explanation:

<u>Midpoint Theorem-</u>

It states that the segment joining two sides of a triangle at the midpoints of those sides is parallel to the third side and is half the length of the third side.

M, N and K are the midpoints of the sides.

So,

  1. KN=\frac{1}{2}AB
  2. NM=\frac{1}{2}CA
  3. MK=\frac{1}{2}BC

Perimeter of a ΔABC is 12 in, i.e AB+CA+BC=12 in

Perimeter of ΔMNK is,

=KN+NM+MK

=\dfrac{1}{2}AB+\dfrac{1}{2}CA+\dfrac{1}{2}BC

=\dfrac{1}{2}(AB+CA+BC)

=\dfrac{1}{2}(12)

=6 in

Goryan [66]

Answer:

<u>The correct answer is B. 2/5</u>

Step-by-step explanation:

This is the information given to us:

A. Shopping preferences for the survey:

1. Mall

2. Stand-alone store

3. Online

B. Paying preferences:

1. Store card

2. Credit card

3. Cash

4. Gift card

5. Check

Assume equal probabilities within categories.

It means that each of the paying preferences has the same probability of being selected, if there are five, it means each paying preference has 1/5 of probability and if we're choosing two of them: gift card or check, we have

<u>1/5 + 1/5 of probability = 2/5</u>

<u>The probability of paying by gift card or check is 2/5</u>
