Can someone help me? I know that t=20 I just don't know how to get there
Aneli [31]
2t/5=8t/20    (both numbers multiplied by 4)

t/4=5t/20    (both numbers multiplied by 5)

3=60/20

⇒ 8t/20 - 5t/20= 60/20

3t/20=60/20

⇒3t=60

t=60:3

t=20

I hope you understand !

A cashier has 26 bills consisting of three times as many ones as fives, one less ten than fives, and the rest twenties. If the v

Let number of  fives = x then number of ones = 3x  and number of tens = x - 1

so we can create the equation 

x + 3x +  x-1 + y = 26  where y = number of twenties
so
5x + y = 27

also we have the equation 

5x + 3x + 10(x - 1) + 20y = 120

18x + 20y = 130..................................(1)
5x    + y    = 27     multiply  by -20:-
-100x - 20y = -540..............................(2)
Adding equation (1) and (2)
-82x = -410
x  = 5,  that is  5 fives

Now plug x = 5 into equation 1:-
18(5) + 20y = 130
20y =  40
y =  2 ,   that is 2 twenties

So the answer is   there are (3x) = 15 ones , 5  fives, 4 tens and 2 twenties
