Identify and solve the inequality that represents how many $20 bills, n, you can withdraw from the account without going below the minimum balance. Question 1

1) 20n+100≤320

2)20n+100≥320

3)n+100≤320

4)100n+20≤320

Question 2
The solution is (BLANk)
.

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)

Hello! i hope this
since the cosine is the ratio of the adjacent side to the hypotenuse, you can see that cos 60° = ½. answer. according to the property of cofunctions (topic 3), sin 30° is equal to cos 60°. sin 30° = ½.
