Answer:
division
Step-by-step explanation:
Try each operation.
48 x -8 = -6 is not correct
48 + -8 = -6 is not correct
48 - (-8) = -6 is not correct
48 / (-8) = -6 is correct
Check you answer by -8 x -6 = 48
Two negatives make a positive.

We all know that,
- All animals have 2 eyes.
- All cows have 4 feet
- All hens have 2 feet
So, Let the no. of cows be x and chickens be y
According to question,
- Total number of eyes = 162
Framing equation,
⇛ Eyes of cows + Eyes of chickens = 162
⇛ 2x + 2y = 162
⇛ 2(x + y) = 162
⇛ x + y = 162/2 = 81 -----------(1)
According to question(Cond.-1)
- Total number of feet = 270
Framing equation,
⇛ Feet of cows + Feet of chickens = 270
⇛ 4x + 2y = 270
⇛ 2(2x + y) = 270
⇛ 2x + y = 135 ----------(2)
Subtracting eq.(1) from eq.(2),
⇛ 2x + y - (x + y) = 135 - 81
⇛ 2x + y - x - y = 54
⇛ x = 54
Putting value of x in eq.(1),
⇛ 54 + y = 81
⇛ y = 81 - 54
⇛ y = 27
⚘ So, Total number of animals,
- Number of cows = x = 54
- Number of chickens = y = 27
Hence, solved !

Answer:
Area of Rectangle = LxB ; Area of Parallelogram = BxH ; Area of Triangle = 1/2xBxH
Step-by-step explanation:
Undermentioned are the formula, procedure, examples for calculating area of following geometric figures
- Area of Rectangle = Length (L) x Breadth (B)
Example : L = 10 ; B = 10
Area = L x B = 10 x 10 = 100
- Area of Parallelogram = Base (B) x Height (H)
Example : B = 10 ; H = 10
Area = B x H = 10 x 10 = 100
- Area of Triangle = 1/2 x Base (B) x Height (H)
Example : B = 10 ; H = 10
Area = 1/2 x B x H = 1/2 x 10 x 10 = 50
Answer:
6,840 casts
Step-by-step explanation:
Assuming that every actor can play each of the 4 roles and that each role is different, the number of possible casts including at least one of sir Ian and Patrick is given by the total number of possible casts (permutation of 4 out of 12 actors), minus the number of casts without sir Ian and Patrick (permutation of 4 out of 10 actors):
There are 6,840 possible casts.
