Answer:
140° and 40°
Step-by-step explanation:
let x be one angle then the other is 
x - 30
Since the angles are a linear pair, theis sum is 180° , then
x + x - 30 = 180, that is
x - 30 = 180 ( add 30 to both sides )
x = 210 ( multiply both sides by 2 to clear the fraction )
3x = 420 ( divide both sides by 3 )
x = 140
and x - 30 = (140) - 30 = 70 - 30 = 40
The 2 angles are 140° and 40°
Hi there,
This is simple. There are 4 bananas. There are 6 apples.
So if they are asking bananas to apples, the ratio would be:
4:6
And if it needs to be simplified,
2:3
I hope this helps you! Have a great day!
x=-6+2y
x=2+2y
by subtraction
___________________________
x=-8
Substitute x by one of the two equations :
x=-6+2y
-8=-6+2y
2y=-8+6
2y=-2
y=-2/2
y=-1
I think this is the answer
I hope I helped you^_^
