Harriet works at the Mint, where new coins are made. Old and fake coins are also destroyed there. Harriet has 10 bags of $1 coins. All 10 bags contain the same number of coins. Harriet knows that nine bags contain only good coins and that one bag contains only fake coins. The fake coins are all about 0.5 gram short. Harriet has forgotten which bag contains the fake coins.
Harriet has a set of scales for weighing like the ones in the illustration. What is the lowest number of times she can weigh bags on the scales in order to find the bag of fake coins?
Answer:
3 times
Step-by-step explanation:
She would have to weigh the fake coins and another bag of real coins to spot a difference, and then she would need to check another bag to see which was correct. Maybe thats right.

{2y=x−4
{4x+3y=5
Answer:
(2, -1)
Step-by-step explanation:
We can subtract x from both sides from the first equation, then multiply the first equation by 4, so it's easier to solve later:
-4x+8y = -16
4x+3y = 5
Then, we can add the 2 equations, so the x cancels out:
11y = -11
y=-1
Now, we can plug y as -1 to any of the equations above:
4x+3*(-1)=5
4x=8
x=2
Therefore, the solution to these 2 equations are (2, -1)
The value of the variables 'x' and 'y' will be 2 and negative 1, respectively.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
The system of equations is given below.
x = 2y + 4 ...1
4x + 3y = 5 ...2
From equations 1 and 2, then we have
4(2y + 4) + 3y = 5
8y + 16 + 3y = 5
11y = - 11
y = -1
Then the value of 'x' is given as,
x = 2 (-1) + 4
x = - 2 + 4
x = 2
The value of the variables 'x' and 'y' will be 2 and negative 1, respectively.

What is Subtraction?Subtraction can be done for any numbers or algebraic expressions. It is the process of taking out certain value from a given amount of number.
The process of subtraction can also be termed as finding difference.
Given is an expression 10x - 2x.
We have to find the difference of these two expressions.
We can add or subtract only the like terms.
Like terms are terms which consist of same kind of variables.
Here 10x and 2x have same variable x.
So they can be subtracted.
10x - 2x = x(10 - 2) = 8x
Hence the difference of 10x and 2x is 8x.
