The sign of the product would be the postitive sign because all three integers have the same sign.
2.5x + 4x = 39
6.5x = 39
x = 39 / 6.5
x = 6
Answer:
80°
Step-by-step explanation:
The sum of the two angles (red and blue) is 145°, so you have ...
(4x +5)° +(6x -10)° = 145°
10x = 150 . . . . . . . . divide by °, add 5, simplify
x = 15 . . . . . . . . . . . divide by 10
Then the measure of the angle of interest is ...
m∠XMN = (6x -10)° = (6·15 -10)° = 80°
<span> C. y= x +6 is the linear equation</span>
