Answer:
3:5
Step-by-step explanation:
5a + 3b = 6b
5a=6b-3b
5a=3b
a/b= 3/5
a:b=3:5
Surely not;
5a+a-9b-6b
6a-15b
So,
5a-9b+a-6b=6a-15b
It's not equal to 6a-15
Answer:
Center and radius of the circle of the equation 
center = ( 4,9) Radius = 1
Step-by-step explanation:
Given -
Equation of circle is 
The equation of circle is represented by
where a and b are center of circle and radius r
Comparing these equation
then a = 4 and b = 9 and r = 1
First let’s write down what 2 fourth would look like. It would look like 2/4 (on the computer/phone it looks a little different, if you were to write it out the 2 would be over the 4). Now think is there anything that 2 and 4 can both be divided by. The answer is yes! They can both be divided by 2. So divide them both by 2. 2 divided by 2 is 1, and 4 divided by 2 is 2. So your answer becomes 1/2, or one half. There is nothing else they can both be divided by so that’s your final answer.
Answer:
Step-by-step explanation:
The marks on both sides of the triangle shows that the sides are equal. This means that the triangle is an isosceles triangle.
This means that
x = 4
Also, in an isosceles triangle, the base angles are equal. Therefore, the sum of the base angles would be 2y.
The sum of angles in a triangle is 180 degrees. Therefore,
2y + 50 = 180
Subtracting 50 from both sides of the equation, it becomes
2y + 50 - 50 = 180 - 50 = 130
2y = 130
y = 130/2 = 65 degrees.
