Answer:

$x=10$

Step-by-step explanation:

Notice that all three sides of the given triangle has one tick mark.

This means that all three sides are congruent, meaning that we have an equilateral triangle.

And for equilateral triangles, all three angles are also congruent.

So:

$\angle CBA=\angle BAC=\angle ACB$

Also, recall that the interior angles of a triangle is always 180. Thus:

$\angle CBA+\angle BAC+\angle ACB=180$

Substitute:

$\angle CBA+\angle CBA+\angle CBA=180$

Combine like terms:

$3\angle CBA=180$

Substitute:

$3(6x)=180$

Multiply:

$18x=180$

Thus:

$x=10$

And we are done!

A map has a scale of 1 cm : 21 km. Two cities are 3.1 cm apart on the map. To the nearest tenth of a kilometer, what is the actu

Galina-37 [17]

To answer the problem above, use the concept of ratio and proportion. The ratio between 1 cm to 21 km should be the same as the ratio of 3.1 cm to the actual distance. Let x be the unknown actual distance and mathematically express the situation,

(1 cm/ 21 km) = (3.1 cm / x km)

This equation gives a value for x which is 65.1 km. Therefore, the answer is letter C.

7x + 2y = 17 2x - 2y = 1 =

DerKrebs [107]

Answer:

$(2,\frac{3}{2}})$

Step-by-step explanation:

For finding the system of equations you can use one of two methods. There's the elimination method and also the substitution method. For this I think the best way we could go at solving this is by using the elimination method. Since we can eliminate the 2y. We can then solve for x and then we'll go from there.

$\left \{ +{{7x+2y=17} \atop {2x-2y=1}} \right. \\\\9x=18\\x=2$

Now that we know what x is we can substitute it for one of the equations and then we will be able to solve for y.

$7x+2y=17\\7(2)+2y=17\\14+2y=17\\2y=3\\y=\frac{3}{2}$

So now we have the x and the y and once we place them together we can get the solution of those two equations, and the solution is $(2,\frac{3}{2}})$ .
