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

monitta

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

Concrete is made by mixing cement, sand, and

prohojiy [21]

Answer:

Step-by-step explanation:

Sum the parts of the ratio, 5 + 9 + 13 = 27 parts

Divide the amount of concrete by 27 to find the value of one part of the ratio.

324 ÷ 27 = 12 ← value of 1 part of the ratio , thus

5 parts = 5 × 12 = 60 ← cement

9 parts = 9 × 12 = 108 ← sand

13 parts = 13 × 12 = 156 ← gravel
