1) Some number plus twenty-one is 24

2) Some number times six is 60

3) Some number divided by nine is two

4) 5 less than a number, k

5) The product of five and a number, added to 10

6) The difference of y and 7

7) The quotient of m and 16 is

8) Twice a number is 18

9) A number increased by 9 is 15

10) A number divided by 8 is 10

1. x + 21 = 24, x = 3

2. 6x = 60, x = 10

3. x / 9 = 2, x = 18

4. k - 5

5. (5x) + 10

6. y - 7

7. m/16

8. 2x = 18, x = 9

9. x + 9 = 15, x = 6

10. x / 8 = 10, x = 80

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°

$12. that is my answer.
