2(n+4) + 6 = (1/2)(3-n)
Then 2n + 8 + 6 = 3/2 - n/2
and 2n + 14 = 3/2 - n/2
(5/2)n = 3/2 - 28/2 = -25/2
-25/2
n = -------------- = -5 (answer)
5/2
First we have to find out the common number of them.
For that purpose, the first number should be divided by next number.
100/20 = 5
20/4 = 5
4/0.8 = 5
we have found that 5 is the common number.
0.8/5 = 0.16
therefore the answer is c
7.8n+10=50
8n+10-10=50-10
8n=40/8
n=5
so,larina can purchase 5 bracelets.
8.375 = 20g + 75
375 = 20g + 75
– 75 = – 75
300 = 20g
15 = g
