A number consists of two digits. The number is 2 more than 8 times the sum of the digits, and if 54 is subtracted from the numbe
Gennadij [26K]

Let the units digit = x

Let the 10s digit = y

Equations

10y + x - 2 = 8 * (x + y)              (1)

10y + x - 54 = 10x + y               (2)

Equation 1

10y + x - 2 = 8 * (x + y)    Remove the brackets on the right

10y + x - 2 = 8x + 8y       Subtract 8y from both sides

10y - 8y + x - 2 = 8x        Subtract 8x from both sides

2y + x - 8x - 2 = 0            Combine

2y - 7x - 2 = 0                  (3)

Equation 2

10y + x - 54 = 10x + y      Subtract 10x

10y - 9x - 54 = y              Subtract y from both sides.

9y - 9x - 54 = 0               Divide by 9

y - x - 6 =  0                     Multiply by 2

2y - 2x - 12 = 0                (4)

Solution

Subtract (3) - (4)

2y - 7x - 2 = 0

2y - 2x - 12 = 0

- 5x + 10 = 0      Subtract 10 from both sides.

- 5x = - 10          Divide by - 5

  x = 2

Use (4) to find y

2y - 2x - 12 = 0         Let x =2

2y - 2(2) - 12 = 0      Remove the brackets

2y - 4 - 12 = 0           Combine

2y - 16 = 0                 Add 16 to both sides.

2y = 16                      Divide by 2

y = 8

Answer 82

I'll leave the check to you, but the answer of 82 is correct.

Neporo4naja [7]
See the attached figure
DB = 4 and DC = 6 , We need to find AD

Using <span>Euclid's theorem for the right triangle
</span><span>
</span><span>∴ DB² = AD * DC
</span><span>
</span><span>∴ 4² = AD * 6
</span><span>
</span><span>∴ 6 AD = 16
</span><span>
</span><span>
</span><span>∴ AD = 16/6 = 8/3 ≈ 2.67
