If x - A = B, what is X?

Mathematics

9514 1404 393

Answer:

  (a)

Step-by-step explanation:

Add A to both sides of the equation:

  X -A +A = B +A

  X = B + A

The sum of the two matrices is the matrix that is the sum of corresponding terms.

  x11 = B11 +A11 = -9+2 = 7

  x12= B12 +A12 = 5-7 = -2

These calculations are sufficient to match the answer with choice (a).

tiny-mole [99]

Answer:

x = 9/2

Step-by-step explanation:

10x = 45 (Multiply both sides by x)

(10x)/10 = 45/10 (Divide both sides by 10)

photoshop1234 [79]

Answer:

350

Step-by-step explanation:

So 25% is just basically 1/4. So multiply 1/4 by 1400 to get 350.

1/4 x 1400/1 = 1400/4 = 350

(just divided 1400 by 4 but I can't really show long division on a computer)
