Answer:
c ?
Step-by-step explanation:
Answer:
It is the second one
Step-by-step explanation:
A proportional relationship happens when you get the same answer every time that you divide the y by the x.
(2,10) (4,20) (6,30)
10/2 = 5
20/4 = 5
30/6 = 5
That is not true for the other tables.
Answer:
(a) x = 
(b) x = 
Step-by-step explanation:
A. sum of angles in a polygon = (n - 2) 180
The polygon given is an irregular pentagon, where n = 5
So that;
sum of angles in a pentagon = (5 - 2) 180
= 3 x 180
= 
Thus,
x + 90 + 76 + 110 + 136 = 
x + 412 = 
x =
- 412
x = 
B. The polygon given is an irregular pentagon, where n = 5.
Let the supplementary angle with angle 38 be represented by y,
y + 38 = 180
y = 180 - 38
= 
y = 
Let the supplementary angle with x be represented by z, so that;
z + 72 + 120 + 100 + 142 = 
z + 434 = 
z =
- 434
= 
z = 
But, x + z = 
Then;
x +
= 
x =
- 
= 
x = 
Answer:
This cannot be solved but it can be simplified
first we open the bracket
so we have
a²- abx/x = 2/3
next we cross multiply so it will be 3(a² - abx) = 2x
we get
3a² - 3abx = 2x
Next we factorise so we can get
3a(a-bx) =2x
I dont know what exactly you where asked but I hop this helps
