Parallel lines will never touch each other while perpendicular forms like an X shape. The slope for the parallel is the same while the perpendicular is a negative reciprocal. (Ex for negative reciprocal. 2/4=4/2)

Solve for U 11=8+u/7.68

BlackZzzverrR [31]

$\begin{gathered}\\ \sf\longmapsto 11=\frac{8+u}{7.68}\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto 11 = \frac{8 + u}{ \frac{192}{25} } \end{gathered}$

$\begin{gathered}\\ \sf\longmapsto 11=\frac{(8+u)×25}{192}\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto 11=\frac{200+25u}{192}\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto 2112=200+25u\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto 2112-25u=200\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto -25u=200-2112\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto -25u=-1912\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto u=\frac{1912}{25}\end{gathered}$

Alternate form:

u=76.48

A diamond ring was reduced from $999.99 to $699.99. Find the percent decrease in the price. Round the answer to the nearest tent

poizon [28]

Answer:

30.0% decrease.

Step-by-step explanation:

A diamond ring was reduced from $999.99 to $699.99

The decrease is; $999.99 - $699.99 = $300.00

Percentage decrease = $\frac{decrease}{original price}$ × 100

i.e percentage decrease = $\frac{300}{999.99}$ × 100 = 30.0003%

And it equals to 30.0% (rounded off to the nearest tenth of a percent)
