Value of (–3/8) × (+8/15). A. 11/15 B. 11/23 C. –1/5 D. –1/3

svet-max [94.6K]

ANSWER

The correct answer is C

EXPLANATION

We want to find the value of

$- \frac{3}{8} \times \frac{8}{15}$

This is the same as:

$- \frac{3}{8} \times \frac{8}{3 \times 5}$

We cancel out the common factors to get:

$- \frac{1}{1} \times \frac{1}{1 \times 5}$

We simplify to get:

$- \frac{1}{5}$

The correct answer is C

Y varies directly as x when x= 3 and y =12 find y when x =12

andrew-mc [135]

$\bf \qquad \qquad \textit{direct proportional variation}\\\\
\textit{\underline{y} varies directly with \underline{x}}\qquad \qquad y=kx\impliedby 
\begin{array}{llll}
k=constant\ of\\
\qquad variation
\end{array}\\\\
-------------------------------\\\\
\textit{we know that }
\begin{cases}
x=3\\
y=12
\end{cases}\implies 12=k3\implies \cfrac{12}{3}=k\implies 4=k
\\\\\\
thus\qquad \boxed{y=4x}
\\\\\\
\textit{when x = 12, what is \underline{y}?}\qquad \qquad y=4(12)$
