Answer:
Yvonne's bill = $16.5
Step-by-step explanation:
let
Total of the bill = a
If they split the bill equally = a/3
Yvonne's bill = 3 + a/3
Victoria's bill = $12
Wanda's bill = $12
a = 3 + a/3 + 12 + 12
collect like terms
a - a/3 = 27
(3a - a )/3 = 27
2a/3 = 27
cross multiply
2a = 81
divide both sides by 2
a = 81/2
a = 40.5
Yvonne's bill = 3 + a/3
Yvonne's bill = 3 + 40.5/3
Yvonne's bill = 3 + 13.5
Yvonne's bill = $16.5
Answer:
It is arithmetic
Step-by-step explanation:
Using the rule T2-T1
We see that 16-22 is -6
We can also try T3-T2
We see that 10-16 is also -6
Their is a constant common difference and that constant common difference is -6.
Hope that helps :)
For the answer to the question above, I'll provide a solution for my answer below.
x^4 - 41x^2 = - 400
<span>=> x^4 - 41x^2 + 400 = 0 </span>
<span>=> x^2 = (1/2) [41 ±√(1681 - 100)] </span>
<span>=> x^2 = (1/2) (41 ± 9) </span>
<span>=> x^2 = 16 or 25
</span>
So, therefore, the answers for your problem are
<span>=> x = ± 4 or ± 5.
I hope my answer helped you. </span>
Answer:
-x(x^2 +4x+5)
Step-by-step explanation:
=-x^3 -4x^2 -5x
Factor out a -x
-x(x^2 +4x+5)
What two numbers multiply to 5 and add to 4
None that are integers so we cannot factor any farther
