Line passes through (2, -1) and slope of 1/3

<h3><u>Step 1</u></h3>

y = mx + b,  Identify:  x = 2, y = -1, slope: \sf \frac{1}{3}

<u>insert following values</u>

\rightarrow \sf -1 = \dfrac{1}{3} (2) + b

<u>multiply</u>

\rightarrow \sf -1 = \dfrac{2}{3}  + b

<u>switch sides</u>

\rightarrow \sf b = -1 - \dfrac{2}{3}

<u>subtract</u>

\sf \rightarrow b = -\dfrac{5}{3}

<u>convert to mixed fraction</u>

\sf \rightarrow b = -1\dfrac{2}{3}

<h3><u>Step 2</u></h3>

y = mx + b,  m = \sf \frac{1}{3}, b = -1\frac{2}{3}

<u>insert following values</u>

\rightarrow \sf y =  \dfrac{1}{3} x -1\dfrac{2}{3}

In 2018 there were 238 Republicans and 201 Democrats in the House of Representatives. Find the percentage of Democrats in the Ho
AnnyKZ [126]

Answer:

45.7% or if rounded, 46%

Step-by-step explanation:

1st, you add up the total of people in the House of Representatives.

238+201=439

Then divide the number of Democrats 201 by the total number 439 to get .457  which is 45.7% or if you need to round 46%

To double check, multiply the total number 439 X 45.7% to get 200.6

Daniel has $100. After he buys 4 pencils and 3 pens, he has $7 left. If each pencil costs $3 more than each pen, is $25 enough t
amm1812

Answer:  Yes, Daniel has enough money to buy 2 pens.

=========================================================

Explanation:

x = cost of one pencil

y = cost of one pen

4x = cost of 4 pencils

3y = cost of 3 pens

4x+3y = cost of 4 pencils and 3 pens

100 - (4x+3y) = amount Daniel has left = 7 dollars

100-(4x+3y) = 7 is one equation we can form

Another equation we can form is x = y+3 because "each pencil costs $3 more than each pen".

Let's plug that into the first equation and solve for y.

100-(4x+3y) = 7

100-(4(y+3)+3y) = 7

100 - (4y+12+3y) = 7

100 - (7y+12) = 7

100 - 7y - 12 = 7

-7y + 88 = 7

-7y = 7-88

-7y = -81

y = -81/(-7)

y = 11.57 is the cost of one pen

2y = 2*11.57 = 23.14 is the cost of two pens.

Since this is less than $25, this means he has enough to buy two pens. This assumes that we either ignore tax, or the tax is already included in the listed prices.
