What is 12.3 + 4.7 estimate sum and difference

To find the estimated sum, round the 2 integers to the nearest whole number.

12.3>12

4.7>5

we round 12.3 to 12 because whenever we're asked to round a number, we always look to the digit to the right of the number, if the digit on the right is greater than or equal to 5, we round up if it's less that 5, we round down.

12+5=17

12.3-4.7

we already rounded 12.3 to 12 and 4.7 to 5 so now

12-5=7

Hope this helps

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4
