Answer: 58
Step-by-step explanation: you have to find what A is first. A plus the angle outside (114) is 180. So 180-114 is 66. 66 = A. You then add 66 with 56 and get 122. You subtract 122 with 180 and get 58, your answer.
Answer:
3s + 7.99 = 71.83
Step-by-step explanation:
How would we find out in real life how much each shirt cost? We'd subtract 7.99 from 71.83 and divide the difference by 3, right??
Let's work that backward. Let's say a shirt cost $6. Three would cost $3(6), or $18. Since each shirt costs $s, our price for 3 shirts is $3s. We have to add shipping to get a total, which we are given. When writing an equation, we leave out labels like $ or meters or books or whatever.
