-5 because it is closest to zero and -17 is farther than zero on a number line :) <span />
18*(1/3) (or one third of eighteen) = 6 dogs
5(n) - 2 = 3
3 · 9(m) =27
1. is 27
3^2(s)= 9 · 5(t) = 45 · 2(r) = 90
2. is 90
The angles with measurements equal to 3x+3 and 2x+22 should add up to 180°. This is because the angle which measures 2x+22 and the angle that is adjacent to the angle measuring 3x+3 are supposed to be congruent. If we mathematically translate the concept above, this can be expressed as,
3x + 3 + 2x + 22 = 180
Combining like terms,
(3x + 2x) + (3 + 22) = 180
Simplifying,
5x + 25 = 180
Transpose the constants to only one side of the equation,
5x = 155
Divide the equation by 5.
x = 31
<em>ANSWER: x = 31</em>
X° + 123° + 90° = 360° (angles at a point)
x° = 360° - 90° -123°
x° = 147°
The answer of x is 147°
Hope I can help you :)
