Mathematics
1 answer:
Serga [27]4 years ago
6 0

Answer:

X = 20

Step-by-step explanation:

The angle are supplementary:

  • Meaning that the two angles = 180°

Equation:

  • 7x + x + 20 = 180

Solve:

  • 7x + x + 20 = 180
  • 8x + 20 -20 = 180 - 20
  • 8x = 160
  • Divide 8 from both sides:
  • <u>x = 20</u>

iragen [17]
All in all, we are selecting from a pool of 17 members (4+9+4 = 17). So seeing we have 4 democrats, the probability would be 4/17.

Normally we would simplify the fraction from there but 4/17 is already the simplified form. Therefore that is already the answer.

4x + 1 = 2x – 5 can someone help me. Whoever gets it right gets it right gets brainliest
castortr0y [4]

Answer:

x=-3

Step-by-step explanation:

subtract "2x" to "4x + 1" and that'll leave -5 by itself and leave 2x+1 on the left and -5 on the right then subtract -1 to -5 and it'll add up to -6 then after that you'd divide 2x to -6 and get -3 and it'll leave 'x' by itself so therefore X = -3
