Answer:

I will just give you the way of solving it

Step-by-step explanation:

First you have to change the sgape of the equation and it will become like this :

-6y=-2x+12

And then:

Y=0.33x+2

And then you have to give values to x and find y

For example i will make x zero (0)

It will become

Y=0.33(0)+12

=+12

And the points are (0,+12)

Go on like this and draw the line

Good luck

AC = ?

cos 34° = $\frac{BC}{AC}$

=> 0.829 = $\frac{6}{AC}$

=> AC = $\frac{6}{0.829}$

=> AC = 7.23763570567

=> AC = 7 km

=> AC = 10 km $\:\:\:\:\:\:\:\:$ (nearest tenth)

A map has a scale of 5 in. = 15 mi. If you measured the distance between two cities to be 26 in. On the map, how many miles woul

Reil [10]

Answer:

Actual distance between the two cities given on the map = 78.0 miles

Step-by-step explanation:

Scale used for the actual distance between two cities on a map is,

5 in. = 15 mi.

$\frac{5}{15}$ in. = $\frac{15}{15}$ mi.

1 mi. = $\frac{1}{3}$ in.

1 inch = 3 miles

Therefore, 26 inches on the map = 26 × 3

= 78 miles

Therefore, actual distance between the two cities given on the map = 78.0 miles
