\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{\underline{m} varies directly with the amount of gallons}\implies \stackrel{months}{m}=k\stackrel{gallons}{g}
\\\\\\
\textit{we also know that }
\begin{cases}
m=1\frac{1}{3}\\
\qquad \frac{4}{3}\\
g=1
\end{cases}\implies \cfrac{4}{3}=k1\implies \cfrac{4}{3}=k
\\\\\\
\boxed{m=\cfrac{4}{3}g}\\\\
-------------------------------\\\\
\textit{what's \underline{m} when g=7?}\qquad m=\cfrac{4}{3}\cdot 7\implies m=\cfrac{28}{3}\implies m=9\frac{1}{3}

You are remodeling your kitchen. You've contacted two tiling companies who gladly told you how long it took their workers to til
Ray Of Light [21]
The answer is 7x = 6(x + 15)

x - Jim's rate
y - Pete's rate
<span>Jim completed half the floor in 7 hours:  7x = half of the floor
</span><span>Pete completed the other half of the floor in 6 hours:    6y = half of the floor
So: 7x = 6y

</span><span>Pete can lay 15 more tiles per hour than Jim: y = x + 15

</span>7x = 6y
y = x + 15

Substitute the second equation into the first one:
7x = 6(x + 15)

Answer:

\displaystyle \large \boxed{y < 5}

Step-by-step explanation:

We are given the Inequality:

\displaystyle \large{ \frac{2y}{2}  <  \frac{10}{2} }

First, we can simplify the expression. On the left side of Inequality, we can cancel 2; on the right side, we can cancel 2 out as well.

Simply, division!

\displaystyle \large{ \frac{ \cancel{2}y}{ \cancel{2}}  <  \frac{ \cancel{10}}{ \cancel{2} }}

2 divides 2 is 1; 2 divides 10 is 5.

\displaystyle \large{ \frac{1y}{1}  <  \frac{ 5}{ 1}}

Generally, it is not recommended to write 1 beside the variable nor write 1 as a denominator.

Simplify the expression:-

\displaystyle \large{ y  <  5}

Therefore, the value of y is less than 5.

Let me know if you have any questions after reading the explanation!
