Solve for U 2=3/u-6 Simplify your answer as much as possible

Mathematics
1 answer:
Tanya [424]3 years ago
3 0

Answer:

u = 3/8

Step-by-step explanation:

Solve for u:

2 = 3/u - 6

2 = 3/u - 6 is equivalent to 3/u - 6 = 2:

3/u - 6 = 2

Bring 3/u - 6 together using the common denominator u:

-(3 (2 u - 1))/u = 2

Multiply both sides by u:

-3 (2 u - 1) = 2 u

Expand out terms of the left hand side:

3 - 6 u = 2 u

Subtract 2 u + 3 from both sides:

-8 u = -3

Divide both sides by -8:

Answer:  u = 3/8

Consider the Matrix shown below:
shepuryov [24]

Answer:

The value of  B_{2,4} - B_{3,2}  is 3 ⇒ 2nd

Step-by-step explanation:

The dimensions of any matrix are (m × n), where

  • m is the number of its row
  • n is the number of its column

Ex: Matrix A of dimensions (2 × 3) has 2 rows and 3 columns, where

A_{1,1} means the element in the 1st row and 1st column

A_{1,2} means the element in the 1st row and 2nd column

A_{1,3} means the element in the 1st row and 3rd column

A_{2,1} means the element in the 2nd row and 1st column

A_{2,2} means the element in the 2nd row and 2nd column

A_{2,3} means the element in the 2nd row and 3rd column

Now lets solve the problem

∵ The matrix B has 3 rows

∴ m = 3

∵ The matrix B has 4 columns

∴ n = 4

∴ The dimensions of matrix B are (3 × 4)

∵ B_{2,4} means the element in the 2nd row and 4th column

∴  B_{2,4} = 9

∵ B_{3,2} means the element in the 3rd row and 2nd column

∴  B_{3,2} = 6

- Find the value of B_{2,4} - B_{3,2}

∵ B_{2,4} - B_{3,2} = 9 - 6

∴ B_{2,4} - B_{3,2} = 3
