Answer:
14 nickels
7 dimes
Step-by-step explanation:
1. find out how many dimes there has to be to get $1.40
1 dime= .10
1.40/.10=14 dimes
14/2=7
so there are 7 dimes
since a nickel is half the amount of a dime there will be twice as many to make up the other half which is $0.70
.70/.05=14
there are 14 nickels
proof:
$0.10(7)+$0.05(14)= $1.40

65 degree angle. I know this because you can obviously see it is an equilateral triangle and that means all the angles are the same.
Well first of all we would have to find 1% of the total seats
but first we need to understand that 38% arent sold, and there are 17,100 left. So to find 1 % we divide 17,100 and 38 so lets do that math:)
17,100 ÷ 38 = 450
so now we know that 1% = 450 seats
lets multiply that by 100 to get how many seats that are in the arena...
450 x 100 = 45,000
so there are 45,000 seats in the arena
hope this helps:)

Collect like terms
15 + 3 + 9x + 7x = y
18 + 16x = y
Recall
b + mx = y
m = 16
b = 18
