Answer - 3

B = 36/ (12-9*5)
B = 36/ (12- 45)
B = 36/ (-33)
E = N/A
D = 3
M = N/A
A = N/A
S = N/A

Answer:

12/11

Step-by-step explanation:

Any work inside parentheses must be done first.

Thus, start with (3 + 6); this equals 9. Then the original expression becomes

36÷{12-(9)*5}

Multiplication and division are done before addition and subtraction. Thus, the next stp is to multiply 9 and 5, obtaining 45, inside the parentheses. This results in

36÷{12-45}, or 36÷{33}, which leads to the answer 36/33, or 12/11.

Sergeeva-Olga [200]

Answer: Janice is 1 inch taller than Krysta.

Step-by-step explanation:

Let the height of Krysta denoted by h .

According to the given statements , we will write height of each person in terms of 'h'.

Kathleen is 6 inches shorter than Krysta.

i.e. Height of Kathleen = h-6

Evan is 13 inches taller than Kathleen.

i.e. Height of Evan = (h-6)+13=h-6+13=h+7

i.e. Height of Evan =h+7

David is 2 inches shorter than Evan.

i.e. Height of David = (h+7)-2 =h+7-2

Height of David =h+5

Janice is 4 inches shorter than David.

i.e. Height of Janice= (h+5)-4=h+1

i.e. height of Janice = height of Krysta+ 1 inch [∵ h= height of Krysta]

⇒ Janice is 1 inch taller than Krysta.

HIJK is a parallelogram because the midpoint of both diagonals is

(1 , 0), which means the diagonals bisect each other

Step-by-step explanation:

If (x , y) is the mid-point of a segment whose end points are $(x_{1},y_{1})$ and $(x_{2},y_{2})$ then,

$x=\frac{x_{1}+x_{2}}{2}$

$y=\frac{y_{1}+y_{2}}{2}$

In a parallelogram, its diagonals intersect each other at their mid-points

that means its diagonals bisect each other

∵ HIJK is a quadrilateral

∵ HJ and IK are its diagonals

∵ H = (-2 , 2)

∵ J = (4 , -2)

- Find the mid point of HJ

∵ $M_{HJ}=(\frac{-2+4}{2},\frac{2+-2}{2})$

∴ $M_{HJ}=(\frac{2}{2},\frac{0}{2})$

∴ $M_{HJ}=(1,0)$

∴ The mid-point of HJ is (1 , 0)

∵ I = (4 , 3)

∵ K = (-2 , -3)

- Find the mid point of IK

∵ $M_{IK}=(\frac{4+-2}{2},\frac{3+-3}{2})$

∴ $M_{IK}=(\frac{2}{2},\frac{0}{2})$

∴ $M_{IK}=(1,0)$

∴ The mid-point of IK is (1 , 0)

∵ The mid-points of HJ and IK are equal

∴ HJ and IK bisects each other

∴ HIJK is a parallelogram because its diagonals bisect each other

HIJK is a parallelogram because the midpoint of both diagonals is

(1 , 0), which means the diagonals bisect each other
