Due to "order of operations" rules, you MUST do the multiplication -5(12x+8) first, eliminating the parentheses long the way:
8 - 60x - 40
Now combine the 8 and -40 and rewrite the entire answer in 2 (not 3) terms.
Answer:
6. x=53 obtuse
7. x=120 obtuse
Step-by-step explanation:
To find x, you need to add up the angle measures you already have and subtract that sum from 180.
For example, on number 6 you have 37 and a right angle (that little box in the corner). That counts as 90, so its 90+37=127. Then, you subtract 180-127=53. That is how you get your answer.

Attached below is the problem that I worked out. And I checked my answer simply by plugging it in
Answer:
16.7 cents for one cookie
Step-by-step explanation:
18 multiplied by 20 is 360. 360 divided by 21.60 equals 16. 66 which rounds to 16.7 cents per cookie
I think the answer is A) 2.
I apologize if this is incorrect
