In the diagram, which angles are vertical angles? Check all that apply.
enyata [817]

If two line crosses, then the vertical angles are the angles opposite each other. In this way, these angles share the same vertex. So, the vertical angles are always equal. Therefore, in this problem, the right answers are:


1. ABE and CBD

Notice that the vertex is B, so these two angles share the same vertex. Accordingly, these two angles are vertical angles.


2. ABC and EBD


The same reasoning is applied here. The vertex is also B. Notice that <em>the angles CBD and ABD add up to 180 degrees. </em>

pav-90 [236]

Answer:

The answer is 36 adults and 88 children.

Step-by-step explanation:

The two equations are:

x+y=124 and 5x+3y=444

Using substitution method:

5x+3(124+x)=444

5x+372-3x=444

2x=72

x=36

5(36)+3y=444

180+3y=444

3y=264

y=88

1/15.999=x/54.5<br> Does anyone know what to do? I keep getting the answer wrong.
kkurt [141]
Hello!

First, let's write the problem.
\frac{1}{15.999}=\frac{x}{54.5}
Let's switch sides now, otherwise, we are going to end up doing it later.
\frac{x}{54.5}=\frac{1}{15.999}
Multiply both sides by 54.5.
\frac{x}{54.5} *54.5 =\frac{1}{15.999}*54.5
We could also rewrite that as,
\frac{54.5x}{54.5}=\frac{1\cdot \:54.5}{15.999}
Simplify.
\frac{54.5x}{54.5}=x
\frac{1\cdot \:54.5}{15.999}=\frac{54.5}{15.999}
x=3.40646\dots
That would be our final answer, we could round it to.
x ≈ 3.40

You can feel free to let me know if you have any questions regarding this!
Thanks!
