When solving this equation: -16 + x = -15 we start with adding 16 to both sides. Why do we use addition?​
Ierofanga [76]

Answer:

So you can cancel out the 16. See, the -16 is negative, and if we add +16 to it, then it cancels out and is 0. That way, you have x=1.

Step-by-step explanation:

-16x+x=-15

+16x      +16

   0+x=1

       x=1

What is -6n+5=1? Thanks!
ivann1987 [24]
You subtract 5 to the other side so it'll read -6n=-4 then divide -6 to the other side and it'll be 2/3

Z varies jointly with y and the square of x. If x=4 when y=−7 and z=−336, find x when z=36 and y=3.
mario62 [17]
\bf \qquad \qquad \textit{direct proportional variation}\\\\
\textit{\underline{y} varies directly with \underline{x}}\qquad \qquad  y=kx\impliedby 
\begin{array}{llll}
k=constant\ of\\
\qquad  variation
\end{array}\\\\
-------------------------------\\\\

\bf \textit{z varies jointly with y and the square of x}\qquad z=kyx^2
\\\\\\
\textit{we also know that }
\begin{cases}
x=4\\
y=-7\\
z=-336
\end{cases}\implies -336=k(-7)(4)
\\\\\\
\cfrac{-336}{-28}=k\implies 12=k\qquad \qquad \boxed{z=12yx^2}
\\\\\\
\textit{when z=36 and y=3, what is \underline{x}?}\qquad 36=12(3)x^2
\\\\\\
\cfrac{36}{12\cdot 3}=x^2\implies \sqrt{\cfrac{36}{12\cdot 3}}=x

The pic is the question
Shtirlitz [24]
The answer is C
Because you have to add them all up. So add the 1/3 and 2/3 which equals 3/3 which is equal to 1. So then you add the 1/6 which equals 2/6 which is equivalent to 1/3 then you add that 1/3 to the last 1/3 which also equals 2/6 and as we established that equals 1/3 so the answer is 1 and 1/3.
