Two adjacent angles have a sum of 100°. The angles have measures ∠1 = 20° and ∠2 = (3x + 15)°. What equation can be used to solve for x?(1 point) Responses 3x+115=20 3 x plus 115 is equal to 20 3x−20=100 3 x minus 20 is equal to 100 3x−100=20 3 x minus 100 is equal to 20 3x+35=100
The correct equation that can be used to solve for x is 3x + 15 + 20 = 100.
Two adjacent angles have a sum of 100°. The angles have measures ∠1 = 20° and ∠2 = (3x + 15)°. What equation can be used to solve for x?
3x+115= 20
3x−20 = 100
3x - 100 = 20
3x+35=100
The correct equation that can be used to solve for x is:
20 + (3x + 15) = 100
The answer choices are:
3x+115= 20
3x−20 = 100
3x - 100 = 20
3x+35=100
The equation that can be used to solve for x is:
3x + 15 + 20 = 100
Simplifying, we have:
3x + 35 = 100
Therefore, the correct answer choice is:
3x + 35 = 100
112-3x+7
The expression 112 - 3x + 7 simplifies to:
112 + 7 - 3x
Combining like terms, we have:
119 - 3x
Therefore, the simplified expression is 119 - 3x.
