Answer:
Lady purchased 12 trinkets costing $0.30 each and 8 trinkets costing $0.65 each.
Step-by-step explanation:
A lady buys total number of trinkets = 20
Cost of each trinket is either $0.30 or $0.65.
Let the number of trinkets is x she purchased for $0.30 and y for $0.65
Then x + y = 20 --------(1)
Since she spends total amount = $8.80
Then the equation will be
0.30x + 0.65y = 8.80 ---------(2)
We replace x = (20 - y) from equation (1) to equation (2)
0.30(20 - y) + 0.65y = 8.80
6 - 0.30y + 0.65y = 8.80
0.35y + 6 = 8.80
0.35y = 8.80 - 6
0.35y = 2.80
y = 
y = 8
Now we put y = 8 in equation (1)
x + 8 = 20
x = 20 - 8
x = 12
Therefore, lady purchased 12 trinkets costing $0.30 each and 8 trinkets costing $0.65 each.
I'm not quite sure but the first one I'm pretty sure....
+3,+5,+7,+9 so then +11,+13,+15,+17,+19
24+11=35 => 6th term
35+13=48 => 7th term
48+15=63 => 8th term
63+17=80 => 9th term
80+19=99 => 10th term
14,34,54,74,94
Each increases by 20...
94+20= 114
114+20= 134
134+20= 154
154+20= 174
174+20= 194
37,46,55,64,73
Each increasing by 9,
73+9= 82
82+9= 91
91+9= 100
100+9= 109
109+9= 118
Answer:

Step-by-step explanation:
To solve for X, Substitute 0 for Y and continue.
To solve for Y, Substitute 0 for X and continue.
Answer:
20
Explanation:
To estimate, we round. 102.3 rounds to 100 and 4.7 rounds to 5; this means we divide 100/5, which is 20.
