2x + 5 = 2x - 8

Add 8 to each side

Subtract 2x from each side

13 = 0 isnt true.

Convert 6 2/3 cups to pints. Express your answer in simplest form.

Dmitry_Shevchenko [17]

First off, let's convert the mixed fraction to "improper", keeping in mind that, there are 2 cups in 1 pint.

$\bf \stackrel{mixed}{6\frac{2}{3}}\implies \cfrac{6\cdot 3+2}{3}\implies \stackrel{improper}{\cfrac{20}{3}}
\\\\\\
\begin{array}{ccll}
cups&pints\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
2&1\\\\
\frac{20}{3}&p
\end{array}\implies \cfrac{\quad 2\quad }{\frac{20}{3}}=\cfrac{1}{p}\implies \cfrac{\quad \frac{2}{1}\quad }{\frac{20}{3}}=\cfrac{1}{p}$

$\bf \cfrac{2}{1}\cdot \cfrac{3}{20}=\cfrac{1}{p}\implies \cfrac{3}{10}=\cfrac{1}{p}\implies p=\cfrac{10\cdot 1}{3}\implies p=\cfrac{10}{3}\implies p=3\frac{1}{3}$

Answer:

WOW that's tough to read all squished together!!!

Jayden and Sheridan both tried to find the missing side of the right triangle. A right triangle is shown. One leg is labeled as 7 centimeters. The hypotenuse is labeled as 13 centimeters.

Jayden's Work

Sheridan's Work

a2 + b2 = c2

a2 + b2 = c

272 + 132 = c272 + b2 = 132

49 + 169 = c

249 + b2 = 169

218 = c2b2 = 120

Square root 218 equals square root c squared.

Square root b squared equals

square root 120.

14.76 ≈ cb ≈

10.95Is either of them correct?

***************************************************

In a right triangle

hypotenuse^2 = leg1 ^2 + leg2^2

13^2 = 7^2 + leg2^2

leg2^2 = 120

leg 2 = 10.9544511501

Basically, whoever said 10.95 is correct.
