In this equation, you have to treat the number in the bracket first on the basis of BODMAS
15 - [-3]- 4
Note that when two minuses come together the product is a plus sign.
15 +3 - 4
You have to add before you subract
18 - 4 =14
Therefore, 15- [-3] - 4 = 14.
5/11 for the marble and ½ for dice
Answer:
6 months, i used the equation from part a so i know it’s right
Step-by-step explanation:
a) 15 + 12x = 87
b) 12x = 87-15=72
72/12 = 6
The answer is y=-8 I’m pretty sure
