Answer:

  • x = 6
  • ∠NBS = 68°

Step-by-step explanation:

The sum of the two adjacent angles is equal to the angle that includes both.

  ∠NBS +∠SBR = ∠NBR . . . . . angle sum theorem

  (12x -4) +42 = (17x +8)

  30 = 5x . . . . . . . . . . . . . . subtract 12x+8

  6 = x . . . . . . . . divide by 5

__

Then the measure of ∠NBS is ...

  ∠NBS = 12x -4 = 12·6 -4

  ∠NBS = 68 . . . . degrees

Twice a number plus twice a second number is 310. The difference between the numbers is 55. Find the numbers by writing and solv
yan [13]

The numbers are 105 and 50

<em><u>Solution:</u></em>

Let "x" be the first number

Let "y' be the second number

Twice a number plus twice a second number is 310

Therefore,

twice of x + twice of y = 310

2x + 2y = 310 ---------- eqn 1

The difference between the numbers is 55

x - y = 55 -------- eqn 2

<em><u>Let us solve eqn 1 and eqn 2</u></em>

From eqn 2,

x = 55 + y ------ eqn 3

<em><u>Substitute eqn 3 in eqn 1</u></em>

2(55 + y) + 2y = 310

110 + 2y + 2y = 310

4y = 310 - 110

4y = 200

<h3>y = 50</h3>

<em><u>Substitute y = 50 in eqn 3</u></em>

x = 55 + 50

<h3>x = 105</h3>

Thus the numbers are 105 and 50

Step-by-step explanation:

81^5 = 3486784401

3486784401/243 = 14348907

Double Check

3486784401 / 14348907=243

So N = 14348907.
