1.  221+ 727  

2.  45+5  

3.  220+ 244  

4.  2( -285)  

5.  (-9)

6. 1665  (multiplying)

7.  -3074 (multiplying)

8.  685 *5

9. - 20  2/9

10. 82575 (multiplying)

Step-by-step explanation:

1.34+914=221

948 =  221+ 727     (subtracting 221 from 948)

2. 16+34=45

50=  45+5    ( adding 5 to 45 to get 50)

3. 46+418=220

464= 220+ 244    ( subtracting 220 from 464)

4. 45-615=2

- 570 = 2( -285)   (dividing -570 by 2)

5. 25-36= (-9)

-9 = -9   ( subtraction)

6. 37 x 45= 1665  (multiplying)

7. 58x (-53)= -3074 (multiplying)

8. 3425= 685 *5  (dividing by 5)

9. 910÷(-45)= 182/ (-9) (dividing both by 5)

= - 20  2/9

10. 367 x 225= 82575 (multiplying)

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.
