Answer:
f=13/9
Step-by-step explanation:
f-8/9=5/9
solution
f=5/9+8/9
f= 5+8/9=13/9
Answer:
C (√10)/2
Step-by-step explanation:
Multiply numerator and denominator by √10. Then you have ...
... (5√10)/10 = (√10)/2
_____
Of course, you can always compare the given answers by using your calculator.
5/√10 ≈ 1.58114
The answer choices are ...
... A: 1.41421
... B: 2.23607
... C: 1.58114 . . . . matches the given expression in value
... D: 0.707107
_____
If you're familiar with the square roots of small integers, you can do this last exercise in your head once you have calculated 5/√10. That is, you can eliminate choices A, B, and D.
... √2 ≈ 1.414; √3 ≈ 1.732; √5 ≈ 2.236
So we have the equations:
y - 4x = 2 --- equation 1
5y - 2x = 1 --- equation 2
(equation 2) * 2
10y - 4x = 2 --- equation 3
(equation 2) - (equation 3)
-9y = 0 so y= 0 and thus x = -1/2

Answer:
The length of the sides are 11.5 + 11.5 + 11 + 11.
Step-by-step explanation:
Because this is the perimeter of a quadrilateral, there have to be four numbers that you add together. Since you cannot divide 45 by four evenly, you have to look at the remainder of the quotient that you get from 45/4. The answer is 11 r1. Now you can take the remainder and split it in half to get 11.5. You have to use that number for two of the sides because this is a quadrilateral. When you add these two sides up, you get 23.0 or just 23. However, you need four sides, so you now take the other two 11s from the division and add those together to get 22. 22 + 23= 45.
I think its A but in inxtinct it telling me D so i would go with it as the correct answerr
Hope this helps
