Answer:
Step-by-step explanation:
ax= 27........I would normally solve this by division....but it says multiply....so multiply both sides by 1/a
example :
3x = 27.....multiply both sides by 1/3
1/3(3/1)x = 27 * 1/3
x = 27/3 which reduces to 9
u have to multiply by the reciprocal of a to get rid of a
Since its before the competition, one person has 13 fireflies already and the other has 6, so, 13+6= 19.

(18-12)^2 / 9+7
6^2 / 9+7
36 / 9 + 7
4 + 7
