The equation y = 1725 - 75x represents the amount of money y (in dollars) left in your lunch account after x weeks. 20 weeks go

garik1379 [7]

Y= -75x +1725
y= -75(20) +1725
y = -1500 + 1725
y= 225 = range
225= -75x +1725
225 - 1725= -75x
-1500=-75x
-1500/-75 = -75x/-75
x = 20 = domain

The length of a room is 18

Virty [35]

Question:

The length of a room is 18 1 /2 feet. If using 1 /4 inch = 1 foot scale, what would be the length of a wall on a blueprint of a floor plan?

Answer:

The length of a wall on a blueprint of a floor plan is $4.625 \text{ or } 4\frac{5}{8} \text{ inches }$

Solution:

Given that,

$Length\ of\ room = 18\frac{1}{2} \text{ feet }\\\\Length\ of\ room = 18.5 \text{ feet }$

The scale given is:

$\frac{1}{4}\ inch = 1\ foot$

To find: Length of a wall on a blueprint of a floor plan

Let "x" be the length of a wall on a blueprint of a floor plan

Then from given,

$\frac{1}{4}\ inch = 1\ foot\\\\x\ inches = 18.5\ feet$

This forms a proportion and we can solve by cross multiplying

$\frac{1}{4} \times 18.5 = x \times 1\\\\x = 4.625\\\\In\ terms\ of\ mixed\ fraction,\\\\x = 4\frac{5}{8}$

Thus length of a wall on a blueprint of a floor plan is $4.625 \text{ or } 4\frac{5}{8} \text{ inches }$
