Rich has a bag of 24 pencils. Each pencil is 19 centimeters long. What is the combined length of the pencils in meters

Roman55 [17]

Multiply the number of pencils by the length to get total centimeters first, then convert to meters:

24 x 19 = 456 cams.

1 meter = 100 cm

Divide total cm by 100 to get meters

456 / 100 = 4.56 meters

James has a dog grooming service. He charges a flat rate of $50 per month, plus $10 per grooming. Bradly does not charge a month

solmaris [256]

Answer:

The numbers of grooming visits for which James and Bradly would charge the same amount is 2

Step-by-step explanation:

Let

w -----> the numbers of grooming visits

y ----> the charge in dollars

we know that

<em>James</em>

$y=10w+50$ ----> equation A

<em>Bradly</em>

$y=35w$ ----> equation B

equate equation A and equation B

$35w=10w+50$

Solve for w

$35w-10w=50$

$25w=50$

$w=2$

therefore

The numbers of grooming visits for which James and Bradly would charge the same amount is 2

Find the equation of a line that passes through the points (-1,5) and (3,-3). Write the equation in slope-intercept, point-slope

Vesnalui [34]

$\bf (\stackrel{x_1}{-1}~,~\stackrel{y_1}{5})\qquad 
(\stackrel{x_2}{3}~,~\stackrel{y_2}{-3})
\\\\\\
slope = m\implies 
\cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{-3-5}{3-(-1)}\implies \cfrac{-3-5}{3+1}\implies -2
\\\\\\
\stackrel{\textit{point-slope form}}{y- y_1= m(x- x_1)}\implies y-5=-2[x-(-1)]
\\\\\\
\boxed{y-5=-2(x+1)}\implies y-5=-2x-2\implies \boxed{\stackrel{slope-intercept~form}{y=-2x+3}}
\\\\\\
\boxed{\stackrel{standard~form}{2x+y=3}}$
