Answer:
- x = 12
- 3x+1 = 37°
- 10x-11 = 109°
- 3x-2 = 34°
Step-by-step explanation:
Perhaps you want to know the value of x or the measures of the angles?
__
Simplifying the given equation, you get ...
(16x -12)° = 180°
16x = 192 . . . . . . . divide by °, add 12
x = 12
(3x+1)° = (3·12+1)° = 37°
(10x-11)° = (10·12-11)° = 109°
(3x-2)° = (3·12-2)° = 34°
x is 12, and the angle measures are 37°, 109°, 34°.
First you would do parenthesis according to the PEMDAS(Parenthesis, Exponents, Multiply, Divide, Add, Subtract) Rule
4 -2(-5a -10) = 30
4 + 10a + 20 = 30
Now you need to add 4 and 20 because they are on the same side
24 + 10a = 30
Now subtract 24 on both sides
24 + 10a = 30
-24. -24
10a = 6
Last divide 10 from both sides
10a/10. = 6/10
a= 6/10
Last simplify (optional but recommended)
a = 3/5 or 0.6
Hope this helped :)
A = 0.6
Answer: Yes
Step-by-step explanation:
From the question, we are informed that a survey was conducted of 880 college students attending the same university and that they were offered a list of 10 different internet service providers and were asked to select the one they prefer.
Basee on this information, if everyone selected equal numbers, each service provider will get (880 / 10 = 88 students). In this case, if someone has 89 votes, this means that another person will get 87 votes while the remaining 8 service providers gets 88 students each. Therefore, the device provider with 89 votes can come out on top.
7x+30= 3x+5x
reason being they are not congent and they share the line so would have to equal 180 and they don't
