What is the value of k in the equation StartFraction k Over 3 EndFraction minus 5 = 34?

12345 [234]

$\huge\text{$k=\boxed{117}$}$

$\displaystyle\frac{k}{3}-5=34$

To find the value of $k$ , we need to isolate it on one side of the equation. Add $5$ to both sides of the equation, then multiply both sides of the equation by $3$ .

$\displaystyle\begin{aligned}\frac{k}{3}-5+5&=34+5\\\frac{k}{3}&=39\\\frac{k}{3}*3&=39*3\\k&=\boxed{117}\end{aligned}$

A cycliest rides at 30 kilometers per hour. how far will travel in 21/2 hours

storchak [24]

Answer:

315 kilometers.

Step-by-step explanation:

30 kilometers = 1 hour

<u>Solution:</u>

30 kilometers = 1 hour
=> 30 x 21/2 kilometers = 21/2 hours
=> 15 x 21 kilometers = 21/2 hours
=> 315 kilometers = 21/2 hours

Hence, in 21/2 hours, the cyclist rides 315 kilometers.

Through (-1,4) and a perpendicular to 4y-2x=12

mart [117]

Answer:

Step-by-step explanation:

$\text{The slope-intercept form of an equation of a line:}\\\\y=mx+b\\\\m-\text{slope}\\b-\text{y-intercept}\\\\\text{Let}\\\\k:y=m_1x+b_1\\\\l:y=m_2x+b_2\\\\\text{then}\\\\k\ \perp\ l\iff m_1m_2=-1\to m_2=-\dfrac{1}{m_1}\\\\k\ ||\ l\iff m_1=m_2$

$\text{We have the equation of a line in the standard form:}\ Ax+By=C.\\\\\text{Convert to the slope-intercept form:}\\\\4y-2x=12\qquad\text{add}\ 2x\ \text{to the both sides}\\\\4y-2x+2x=2x+12\\\\4y=2x+12\qquad\text{divide both sides by 4}\\\\\dfrac{4y}{4}=\dfrac{2x}{4}+\dfrac{12}{4}\\\\y=\dfrac{1}{2}x+3\to\boxed{m_1=\dfrac{1}{2}}$

$\text{Therefore}\ m_2=-\dfrac{1}{\frac{1}{2}}=-2.\\\\\text{Put the value of the slope and the coordinates of the given point (-1, 4)}\\\text{to the equation of a line:}\\\\4=-2(-1)+b\\\\4=2+b\qquad\text{subtract 2 from the both sides}\\\\4-2=2-2+b\\\\2=b\to b=2\\\\\bold{FINALLY:}\ y=-2x+2$

$\text{Convert to the standard form:}\\\\y=-2x+2\qquad\text{add}\ 2x\ \text{to the both sides}\\\\y+2x=-2x+2x+2\\\\2x+y=2$
