The coefficient of ALL variables is the number in front of the variable, which here its -9
Answer:
5/3
Step-by-step explanation:
1/2 x = 5/6
Multiply by 2 on each side
(1/2 * 2)x = (5/6)2
x = 5/3
38/244= about 0.16
24/943= about 0.03
653/53= about 12.32
All answers are rounded
4 is missing I assume. But I could be wrong
1: establish the angles, basically label one x (the small one) and the other y (the bigger one)
2. supplementary angles add up to 180, so therefore you have the equation x + y = 180.
3. so y (the bigger one) is 8 less than 3 times the smaller one (x) therefore you come up with the equation y = 3x - 8
4. plug in the equation of the bigger one into the other equation
x + 3x - 8 = 180
(combine like terms)
4x - 8 = 180
5. solve the equation by adding 8 to 180, then by dividing by 4.
x should equal 47
6. plug in 47 into the x + y = 180 equation, subtract 47 from 180 and you end up with 133
i hope i explained it alright
