The sum of 38 and twice a number x is 124. The value of "x" is 43

- 2x - 5 is equal to – 91.

<u>Solution:</u>

Given that , The sum of 38 and twice a number x is 124.  

We have to find what is - 2x - 5?

Now, according to given information, 38 + 2 × x = 124  

2x + 38 = 124  

2x = 124 – 38  

2x = 86  

x = 43

So, the value of x is 43

<em><u>Now, Evaluating - 2x – 5  </u></em>

Substitute "x" = 43 to evaluate

- 2(43) – 5  

- 86 – 5  = - 91

Hence, the required answer is – 91.

castortr0y [4]

Step-by-step explanation:

for a

  • a+,38°=90°{ angle at circumference through center is 90°}
  • a=90-38
  • a=52°

for e

  • e=38°{base angle of isosceles triangle r equal}

for d

  • 38°+e+d=180°{sum of angle of triangle}
  • d=180-76
  • d=104°

for. c

  • c+d=180°{straight angle}
  • c=180-104°
  • c=76°

for b

  • a+b+c=180°{sum of angle of triangle}
  • b=180-128
  • b=52°

hope it helps.
