Answer:15j+15
Step-by-step explanation:
First you do 5*2j and 5*3 and 5*j which is also 5*1j
Then you get 10j+15+5j
Then you add 10 and 5 j since they are like terms and then you get 15j+15
Answer:
200
Step-by-step explanation:
Given that :
16% of coins are quarters from 1990
Number of quarters from 1990 = 32
Since 16% = 32 quarters
The number of the total coins can be obtained thus :
Let the total number of coins = x
16% = 32
100% = x
Cross multiply :
0.16x = 32 * 1
0.16x = 32
x = 32 / 0.16
x = 200
Hence, total number of coins in the collection = 200
