6 < 3b or 3b + 12 < 9
2< b Or 3b < -3 You can only change the sign should you multiply or divide the negative number.
<span>2 < b or b < 1 that means b > 2
Hope this helps :)</span>

Answer:
(25,12)
Step-by-step explanation:
pattern A=20+5
=25
pattern B=14-2
=12
25,12
We used the elimination method to find the ordered pair, (x,y), that represents the situation is (12,39).
Number of invoices = 51
Charge for tree installation = $375
Charge for tree trimming = $54
Total amount in invoices = $6,606
Let x and y represent number of installations and number of trimmings respectively.
Hence,
x + y = 51 ...(1)
375x + 54y = 6606
3 (125x + 18y) = 3*2202
125x + 18y = 2202 ...(2)
Multiplying (1) by 18, we get
18x + 18y = 918 ...(3)
(2) - (3)
107x + 0 = 1284
x = 1284/107 = 12
Hence,
y = 51 - 12 = 39.
