Answer:

63

Step-by-step explanation:

If x units, then 2x tens

Number is: 2x(10)+x = 21x

Reversing digits:

2x units and x tens,

Number is: x(10)+2x = 12x

21x - 12x = 27

9x = 27

x = 27/9 = 3

Original number: 21x = 21(3) = 63

adelina 88 [10]

Answer:

<OPQ = 23 degrees

Step-by-step explanation:

Given

Interior angles m∠PNO=(x+14) and m∠NOP=(x−1)

Exterior angle = m<OPQ = (5x-2)

The sum of interior angles is equal to the exterior angle, that is;

m∠PNO+m∠NOP = m<OPQ

x+14 + x-1 = 5x-2

2x + 13 = 5x-2

Collect like terms;

2x-5x = -2-13

-3x = -15

x = 15/3

x = 5

Get <OPQ

<OPQ = 5x - 2

<OPQ = 5(5)- 2

<OPQ = 25-2

<OPQ = 23 degrees
