-1 / 7 = x
You need to combine the 2x and 5x then devise the 7x from -1
Answer:
p = 56.7°
n = 123.3°
Step-by-step explanation:
The sum of linear pair angles is 180° because, because a linear pair angles, are angles formed by two intersected lines and the angle of a straight line is 180°.
Then your first equation is:
n + p = 180°
The second equation can be formulated with the information given:
"angle n is 10 more than twice the measure of angle p."
n = 10 + 2p
Replacing in the first equation:
10 + 2p + p = 180°
3p = 170°
p = 56.7°
n = 123.3°
Set up an equation to see how this makes sense.
Let X be your original number.
So...
2(3x-7)-22/6=-3
6x-14-22/6=-3
6x-36/6=-3
6x-36=-18
6x=18
X=3
Answer:
6 students.
Step-by-step explanation:
let the number of students in class be<em> x</em>
Since Half of the class represents half of the students, therefore
Number of student who got A in test = 
Now if one more student got A in test then the number of students who got A in test will be 
Now according to equation,
Further solving
Hence the total number of students in class is 6.
