Answer: 76 child tickets were sold that day.

Step-by-step explanation:

You need to set up a system of equations.

Let be "c" the number of child tickets sold that Wednesday and "a" the number of adult tickets sold that Wednesday.

Then:

\left \{ {{a+c=173} \atop {9.40a+5.70c=1345.0}} \right.

Using the Method of Elimination, you can multiply the first equation by -9.40, then add both equations and finally solve for "c":

\left \{ {{-9.40a-9.40c=-1626.2} \atop {9.40a+5.70=1345.0}} \right.\\..................................\\-3.7c=-281.2\\\\c=\frac{-281.2}{-3.7}\\\\c=76

When analyzing the list of nouns to determine whether to exclude a particular noun as an important "thing," which of the followi
anyanavicka [17]
<h2>Answer:</h2>

<em><u>(a) Is it an output from the system? </u></em>

<em><u>(d) Is it a synonym of an existing thing?</u></em>

<h2>Step-by-step explanation:</h2>

In the question,

We have a list of nouns and we need to determine whether a particular noun should be excluded by identifying particular noun as an important 'thing'.

So, to identify it as a noun we can ask two questions which will distinguish between the same.

<u>(a) Is it an output from the system? </u>

It is one of the questions that can be asked because if the thing is an output from a system it will be definitely existing in real therefore, we can identify from this.

<u>(d) Is it a synonym of an existing thing?</u>

By asking this we can also confirm whether a particular thing is a noun or not because if the thing will be a synonym for an already existing material, it definitely will be a Noun.

<em><u>Therefore, the correct option is (a) and (d).</u></em>

Translate each phrase and select the one that is DIFFERENT from the others. two more than a number, n the total of n and 2 twice
tensa zangetsu [6.8K]

Answer:

Option C.

Step-by-step explanation:

We need to translate each phrase and find the different expression.

"+" sign is used for sum, more and total.

Twice means two times of a number.

Let n be the unknown number.

Two more than a number = n+2

The total of n and 2 = n+2

Twice the number n = 2n

Sum of n and 2 = n+2

From the above expressions it is clear that only 2n is different from other.

Therefore, the correct option is C.

Can anyone help I have tried finish for days

Answer:

34 degrees.

Step-by-step explanation:

First of all, the sum of a triangle's degree is 180.

The angle next to the 101 is 79 degree due to the rule of supplementary angle. The angle vertical to 28 is also 28. (Vertical angles are equal).

Now we now the two side, we can figure out the last side.

180-28-79= 73

The last angle is 73 degrees. However, we are looking for x.

x+39=73

All we have to do now is subtract 39 from 73, and that leaves us with 34.
