All you do is 1x+2x+5x=8x then you turn 4 s into pints. 1 gallon equals 4 pints 4*4=16 pints. 8x=16 x=2. Then you multiply everything by 2
1*2=2
2*2=4
2*5=10

It's between 2,000 and 3,000. Also 2,020 and 2,030. (The answer is 2,023.) c:
Answer:
m = -1
Step-by-step explanation:
12 times the number is 12m
17 less than that is 12m -17.
23 less than 6 times the number is 6m-23.
These expressions are said to be the same:
12m -17 = 6m -23
6m -17 = -23 . . . . . . . . subtract 6m from both sides
6m = -6 . . . . . . . . . . add 17 to both sides
m = -1 . . . . . . . . . divide both sides by 6
The value of m is -1.

Answer:
Step-by-step explanation:
Let d represent the number of dimes. Then 81-d is the number of nickels and the total value in cents is ...
10d +5(81-d) = 530
5d +405 = 530 . . . eliminate parentheses
d +81 = 106 . . . . . divide by 5
d = 25 . . . . . . . . . subtract 81; number of dimes
81 -d = 81 -25 = 56 . . . . . number of nickels
There are 25 dimes and 56 nickels in the box.
