Answer:
n = 6
Step-by-step explanation:
4(3-6n)-4n=-156 (by PEDMAS, solve parentheses first)
(4)(3) - (4)(6n) - 4n = - 156
12 - 24n - 4n = -156
12 - 28n = -156 (subtract 12 from both sides)
-28n = -156 - 12
-28n = -168 (divide both sides by -28)
n = -168 / (-28)
n = 6
The operation of this problem is B multiplication
The answer is 145 divided by tan 65 degrees.
Since the equation for tangent is opposite/adjacent, you can just plug the numbers in.
tan(65)=145/x (x being the height that you are trying to find)
tan(65) * x = 145
Then divide tan(65) to isolate the x and you get:
145/tan(65)

So she needs .25 kg more dirt or 250g of dirt.
