Answer: 2(x+y)-25
Step-by-step explanation:
First, we need to show the sum of Roger and Olivia's heights. If Roger is x and Olivia is y, the sum is <em>x+y</em>
Next, we need to double that. To double something we multiply it by 2. Since we need double the expression we found above, we put it in parentheses. So the doubled sum is shown as <em>2(x+y)</em>
Finally, we need to show that Isabella is 25 centimeters shorter than the doubled sum. To do that, subtract 25.
The final expression for Isabella's height is 2(x+y)-25
Answer:
B) $30.87
Step-by-step explanation:
28.45*0.085=2.41825
When rounded to the nearest cent, you get 2.42.
28.45+2.42=30.87
The total cost after tax is $30.87.
The set of possible integers is 1, 2, 3, 4, and 5.
The area of a circle with radius of n centimeters = π(n)^2.
So, the set of possible values are:
n area = π(n^2)
1 π
2 4π
3 9π
4 16π
5 25π
And the expected value of the area may be determined as the mean (average) of the five possible areas:
expected value of the area = [ π+ 4π + 9π + 16π + 25π] / 5 = 11π ≈ 34.5575, which rounded to the nearest hundreth is 34.56
Answer: 34.56

Answer:
9s+2=9s-5
Step-by-step explanation:
2 times 9s and 2 times 2 then subtract your 9sequals 3 times 3sand 3 times 6 so then you get 9s and 18 then you subtract 23 and you get 23. then you get your answer 9s-5=9s+2
