Answer= 6.5y+12

distribute the 5 in the parentheses:
(-6y-3) + (15+12.5y)
(you can take away the parentheses after this step)

then add like terms together.
12.5y + (-6y) = 6.5y
15 + (-3) = 12

make it one expression.
6.5y + 12

Prove that for all n in the naturals, n(n+1)(n+2) is divisible by 3
DerKrebs [107]
By induction:

It's true for n=1, since 1\cdot2\cdot3 clearly contains a factor of 3.

Suppose it's true for n=k, that k(k+1)(k+2) is divisible by 3. Then

(k+1)(k+2)(k+3)=\dfrac{k(k+1)(k+2)(k+3)}k=\dfrac{3m(k+3)}k

where m is an integer. This reduces to

\dfrac{3m(k+3)}k=3m+9\dfrac mk

and both terms are clearly multiples of 3. We know that \dfrac mk is an integer since we had set m=k(k+1)(k+2) previously, which implies m is a multiple of k. So the statement is true.

Simplify (1-b/a)÷(1-a/b)​
TEA [102]

Answer

\frac{ba-b^{2} }{ab-a^{2} }

Step-by-step explanation:

\frac{1-\frac{b}{a} }{1-\frac{a}{b} } = \frac{\frac{a-b}{a}}{\frac{b-a}{b}} = \frac{b(a-b)}{a(b-a)}

\frac{ba -b^{2} }{ab-a^{2} }

Select the statement in if-then form.
SashulF [63]
The correct statement is C. <span>If an angle is an acute angle, then the angle measures less than 90 degrees. 
A and B are obviously incorrect, and D is incorrect because it can be other angle as well, not just acute. </span>
