Try this
(x^2 + x - 12) + (x^2 - 8x + 16)
2y - 1

i wanted to help you! :)
Your answer is -4.23 degrees fahrenheit.
To get that answer you must take you starting temperature, 9.17, and your decreased amount of temperature, 13.4, and subtract them.
So, you have 9.17 - 13.4 = -4.23
You can not reverse the numbers or it will give you the wrong answer.
Answer:
There is not even a question what shall I answer
Step-by-step explanation:
Let us take number of $5 bills = x and
number of $10 bills = y.
Give that "number of $10 bills is twice the number of $5 bills".
So, y is twice of x,
We can setup an equation.
y= 2x ............................... equation(1)
Total value of all bills = $125.
We can setup another equation,
5*(number of $5 bills) + 10*(number of $10 bills) =125.
5(x) +10(y) = 125 ................................... equation(2)
Plugging y=2x in equation(2), we get
5(x) +10(2x) = 125 .
5x+20x = 125.
Adding like terms
25x = 125
Dividing both sides by 25.
25x /25 = 125/25
x= 5.
Plugging x=5 in first equation, we get
y= 2(5) = 10.
Therefore, number of number of $5 bills=5 bills and number of $10 bills = 10 bills.
Answer: 1.55 and 0.65 in order
Step-by-step explanation:
6.19 / 4 = 1.55 and that is in the first box
4 / 6.19 = 0.65 and that is in the second box
