Answer:
AOC = 124°
Step-by-step explanation:
Angle on a straight line is 180°, therefore, the sum of the three angles shown is 180;
This can be written like so:
(3x + 94) + (x + 30) + (2x - 4) = 180
This equation can be solved to find x:
6x + 120 = 180
6x = 180 - 120
6x = 60
x = 10
AOC = 3(10) + 94
= 30 + 94
= 124
Answer:
- Blue - 18, green - 50, with photo - 37
Step-by-step explanation:
<u>Total number = 150</u>
- Blue = 150/8 = 18 (integer part)
- Green = 150/3 = 50
- Spaceman Spiff autograph = 150/4 = 37 (integer part)
<span>-2x – 4 < 10
add 4 to both sides
-2x - 4 + 4 < 10 + 4
simplify
-2x < 14
divide both sides by -2
-2x/-2 < 14/-2
simplify
x < -7</span>
Answer:
It was helpful to construct points D and A to be the same distance from C because it gives you an equal arc on both sides, which will intersect twice, forming a colinear line that is perpendicular to line AB.
Step-by-step explanation:
Answer:
4.5 is a rational number, as it can be represented as 9/2. Many important numbers in mathematics, however, are irrational, and cannot be written as ratios.
