Answer:
C. 14,871.21
Step-by-step explanation: You take the number 29,742.42 and multiply it by .2 to get how much they spend on food (5,948.48), and you multiply the same number by .3 to get how much they spend on housing (8,922.73). Then, you add them up to get the total. .2 is acctually 20% of what they spend out of the 29,742.42 and the same for the .3. Hope this wasn't too complicated by the way I explained it.
23≤x≤400
x∈[23;400] x has to be equal or more than 23 and max 400 so 400or and less than that
Answer:
I got 42
Step-by-step explanation:
They should add up to 180 cause parallel lines and similar angles. (3x-5)+(2x-25)=180 then just solve
We need to solve for the values of x by applying the method of completing the square in the given expression x² - 10x -2 = 17. The solution is shown below:
x² - 10x -2 = 17
Transpose -2 to the right side such as:
x² - 10x = 17 + 2
Perform addition of 17 and 2
x² - 10x = 19
Add + 25 in both sides
x² - 10x + 25 = 19 + 25
x² - 10x + 25 = 44
(x-5)(x-5) = 44
Where (x-5) is a perfect square, then we have:
(x-5)² = 44
x1 = +√44 -5 = 1.6
x2 = - √44 -5 = -11.6
The answers are x1=1.6 and x2 = -11.6.
