Answer:
x = negative 9 or x=-9
Step-by-step explanation:
4x+24=2x+6. We can subtract 6 from both sides to get
4x+18=2x. After that, we can switch the sides to get
2x-18=4x, so negative 18 (-18) is equivalent to 2x. We get
2x=-18, divide both sides by 2 to get x=(-9).
What kind of math is this
Answer:
65º
Step-by-step explanation:
- The angle of a straight line is 180º, so ∠ABD=180º and ∠ABC=(180-6x)º
- The sum of the interior angles of a triangle is 180, so (x+40)º+(3x+10)º+(180-6x)º=180
- We can solve from there, x+40+3x+10+180-6x=180
- Combine like terms, -2x+230=180
- Subtract 230, -2x=-50
- Divide by -2, x=25
- m∠CAB=(x+40)º=(25+40)º=65º
- m∠ABC=(180-6x)º=(180-150)º=30º
- m∠BCA=(3x+10)º=(75+10)º=85º
