I am an odd Number my digits add up to 7 I am bigger than 50 and smaller than 100 who am i?

61

Step-by-step explanation:

1) When it says it's an odd number, the ones place has to 1, 3, 5, 7, or 9

2) Since the number is bigger than 50 and smaller than 100, we know the answer is going to be ranging in somewhere between 50 and 70

3) Now, we have to make sure the digits add up to 7, so no we are left we the options 52, 61, and 70

4) We have to make sure the answer is an odd number. Therefore, 61 is the correct answer.

Hope this helps!

step-by-step explanation:

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
