The answer is 0.8 kilowatts because 4 divided by 5 is 0.8
Answer: 5-2x=6-x, x= -1/3
Explanation:
“When I double it and subtract it from five it is the same as subtracting it from six”
So double means multiply by two, and the same as means equal. Use a variable to represent the number.
Therefore your equation is:
5-2x=6-x
So solving the equation would be:
-2x-x = 6-5
-3x = 1
x= -1/3
The square of a binomial is a pattern you would do well to remember.
.. (x +y)^2 = x^2 +2xy +y^2
Your expression has x^2 = 25a^2, so x = 5a. It also has y^2 = (b^2)/4, so y = b/2.
then the middle term is
.. 2xy = 2(5a)(b/2) = 5ab
The trinomial is
.. 25a^2 +5ab +(1/4)b^2 = (5a +b/2)^2
It would equal five degrees Celsius
