Answer:

x = -3/8

Step-by-step explanation:

4(3-2x)=15

Distribute

12 -8x = 15

Subtract 12 from each side

12-8x-12 = 15-12

-8x =3

Divide each side by -8

-8x/-8 = 3/-8

x = -3/8

\text{Solve for x:}\\\\4(3-2x)=15\\\\\text{Use the distributive property}\\\\12-8x=15\\\\\text{Subtract 12 from both sides}\\\\-8x=3\\\\\text{Divide both sides by -8}\\\\\boxed{x=-\frac{3}{8}}

Scale on map is Lin 86 mi if actual distance is 35 mi . Between two cities how far apart on the map are they
Mrac [35]

Answer:

0.41 cm

Step-by-step explanation:

The scale on the map is 1 in 86 mi.

This means that, 1 cm on the map represents 86 miles in real life, or on earth.

Then we're told that in real life, a distance is 35 miles, and how far they are on the map.

If 1 cm equals 86 miles, then we can say that x cm equals 35 miles

1 cm ----> 86

x cm ----> 35

x * 86 = 35 * 1

x = 35 / 86

x = 0.41 cm

Therefore, they must be 0.41 cm farther or closer apart on the map scale.

If (m, 2) is on a circle with center (−3, 2) and radius 8, what is a value of m?
Talja [164]
\bf \textit{distance between 2 points}\\ \quad \\
\begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
%  (a,b)
&({{ -3}}\quad ,&{{ 2}})\quad 
%  (c,d)
&({{ m}}\quad ,&{{ 2}})
\end{array}\qquad 
%  distance value
d = \sqrt{({{ x_2}}-{{ x_1}})^2 + ({{ y_2}}-{{ y_1}})^2}

\bf \textit{we know the distance from m,2 and -3,2(center) is the radius}
\\\\\\
d=8\implies 8=\sqrt{[m-(-3)]^2+[2-2]^2}
\\\\\\
8=\sqrt{(m+3)^2+(0)^2}\implies 8=\sqrt{(m+3)^2}\implies 8^2=(m+3)^2
\\\\\\
64=(m+3)^2\implies \sqrt{64}=\sqrt{(m+3)^2}\implies 8=m+3
\\\\\\
8-3=m
