Answer:x=1/2
Step-by-step explanation:5x-5-6x=-11x
-x-5=-11x
-x+11x=5
10x/10=5/10
X=1/2
Answer:
Step-by-step explanation:
Given the expression in the form , we know that Victoria can simplify it by adding the like terms:
She can also factor out -6:
Now, she needs to factor the coefficient of the second term rewrite it as (1-2), then:
Now she needs to group the terms as following:
And factor out 2x:
Finally, she has to factor out . Therefore, she gets:
You can use calculus ( related rates). Given the rate os change of the radius for example you can find the rate of change of volume using differential calculus.

Answer:
18
Step-by-step explanation:
Solve the first for a, then substitute into the second.
a = 27/(5b^2)
Then ...
(27/(5b^2))^2·b = 135
27^2/(5^2·135) = b^3 = 27/125
b = ∛(27/125) = 3/5
a = 27/(5(3/5)^2) = 15
__
The expression of interest is ...
a +5b = 15 + 5(3/5) = 15 +3
a +5b = 18
