Evaluate the trigonometric expression using sum and difference formulas.
Answer:
-1½ = b
Step-by-step explanation:
Combining all like-terms on the right side of the equivalence symbol will give you this:
4b + 6 = 0
- 6 -6
------------
4b = -6 [Divide by 4]
b = -1½ [OR -1,5]

Answer: I hope this is what you meant :)
- The sum of 5 and and unknown number is multiplied by 3
- 3 multiplies the sum of 5 and an unknown number.
Step-by-step explanation:
To find the average over 5 times, we have to divide the total by 5. Therefore, 260/5 = 52 = the average change in your account balance each trips. 260 = amount of money you withdraw, 5 = number of trips made by the ATM. We need to divide due to that if something is spread out equally 5 times, what you get in one time clearly won't be all of it
