The distance between City A and City B is 250 miles. A length of 1.7 feet represents this distance on a certain wall map. City C
Xelga [282]
The scale of the map is equal to 250 miles per 1.7 feet. or 250m/1.7ft. set up as a fraction.
Divide 250 by 1.7 to get how many miles are equal to just 1 foot.
250/1.7 = 147.058824 miles per 1 foot
Multiply that times 3.06 feet (the distance between C and D on the map)
147.058824m/1ft x 3.06ft = 450m
The actual distance between City C and City D should be 450 miles.

Answer:

<h3>(-4, 1)</h3>

Step-by-step explanation:

-x-3=y, therefore x = -y-3

-3x - 8y = 4

Find the value of y

Substitute the x in -3x - 8y = 4 with -y-3

We get

-3·(-y-3) - 8y = 4

3y + 9 - 8y = 4

-5y = 4-9

-5y = -5

<h3>y = 1</h3>

_______________

Find the value of x

x = -y-3

x = -1-3

<h3>x = -4</h3>

_______________

Answer (x, y) =

<h3>(-4, 1)</h3>
