A] The expression of the number of $20 will found as follows:
given that the number of $10 is x,
The total number of denominations is 22, then the number of $20 will be given by the equation:
22-x
b] The total number of each denomination will be evaluated as follows:
total amount of money will be given by the equation:
10*x+20(22-x)=300
solving for x:
10x+440-20x=300
10x-20x=300-440
-10x=-140
thus
x=-140/(-10)
x=14
thus the number of $10 denominations was 14 and the number of $20 denominations was 22-14=8
Answer:
X =7
Step-by-step explanation:
find x;
45 IS base,
so 45 power X = 45^7
45^x = 45^7
45 will cancel out remaining x=7
therefore x= 7
Answer:
Step-by-step explanation:
Ok so this is simple
6+7+0=13
3 will be in the ones column and the one would be carried over in the tens column so it would be
1+8+4+7=20
again 0 will be in the tens column and 2 would be carried over in the hundreds column so
2+5+0+6=12
2 in the hundreds column and 1 carried over in the thousands column
1+9+1+7=18
8 in the thousands column and over carried over in the ten thousands column
1+3+4+5=13
13 would be written in the ten thousands column as it is the last one
The total would be
138303
Hope this helps :)
