<span>-(x + 5) = 5
-x - 5 = 5
-x = 5 + 5
-x = 10
x = -10</span>
Since they are consecutive, we can define the two unknowns with ease.
The left page (has a smaller value) can be defined as X, and the right page can be defined as X+1.
So,
X + (X+1) = 293
2x+1 = 293
2x = 292
x = 146
So, as we defined before, the smaller page number is equal to x. Therefore, the smaller page number is 146, and the larger page number is 147.
Step-by-step explanation:
When you complete the square, you change the equation so that the left side of the equation is a perfect square trinomial. But mainly completing the square is a technique that transforms your quadratic equation from an equation that can't be factored into one that can.
Answer:
448.50
Step-by-step explanation:
299/2 = 149.50
then you take 149.50* 3 to get your answer and that = 448.50
Answer:
it`s not true that for every person, if the person is happy, the person has a large income/there are people that are happy and doesn't have large incomes
Step-by-step explanation:
let be x the group of people in the world
let be I(X)=x has a large income
let be H(x)=x is happy
Having a large income is not a necessary condition for a person to be happy.
¬∀x, H(x)-->I(x)
<em>it`s not true that for every person, if the person is happy, the person has a large income</em>
∃x / H(x)^¬I(x)
<em>there are people that are happy and doesn't have large incomes</em>
