Answer:
14.5 i think
Step-by-step explanation:
2.5 + 12 = 14.5
Answer:
y = 4
Step-by-step explanation:
2x + 3y = 6
2x + y = -2
Let's set the second equation equal to y. This means that y will be alone on one side of the equal sign.
2x + y = -2
Subtract 2x from both sides.
y = -2x - 2
Now that we have y as an expression, plug it into the first equation.
2x + 3y = 6
2x + 3(-2x - 2) = 6
Distribute the 3 across the parentheses by multiplying.
2x - 6x - 6 = 6
Combine like terms.
-4x = 12
Divide both sides by -4.
x = -3
Now we have solved x.
To solve for y, plug x back into one of the equations.
y = -2x - 2
y = -2(-3) - 2
Multiply.
y = 6 - 2
Subtract.
y = 4
Check your answer by plugging both values back into the original equations.
2x + 3y = 6
2(-3) + 3(4) = 6
Multiply.
-6 + 12 = 6
Add.
6 = 6
Your answer is correct.
Hope this helps!
Answer:
The solution is:
$160 for booth + $16 needles = $176 as capital
$15 price to sell each scarf - $4 cost of the yarn to make
the scarf = $11 as profit
$176 / $11 = 16
The students must sell 16 pieces of scarves to get the
break even point of $176 for the capital
Answer:
The possible values for X is: 
Yes, it is a discrete random variable.
Step-by-step explanation:
Consider the provided information.
We need to determine whether the variable is discrete or not.
Discrete variables are which can only take on a finite number of values.
Let the variable X be the number of unbroken eggs in a randomly chosen standard egg carton.
In a standard egg carton we can put 12 eggs.
Therefore, the possible values for X is:
The number of unbroken eggs (X) can take infinite values, thus by the above definition it is a discrete random variable.
