<span><u><em>Answer:</em></u>
1. 3x = y
2. 7x= y.
<span>
<u><em>Explanation:</em></u>
If x is the amount of points each question that is answered correctly received then the coefficient that x is multiplied by will be the amount for each test.

For the first equation we have 3 as the amount answered correctly time x the points each one is worth = total points y.

For the second equation we have 7 as the amount answered correctly time x the points each one is worth = total points y .

Answer with explanation:

→For, x correct answer number of points scored = y

For ,1 correct answer number of points scored=\frac{y}{x}

→The statement about the problem is

On his first geography test, Enrique answered 3 questions correctly. On his second test, Enrique answered 7 questions correctly.

Writing the statement in terms of equation

In First test

For, three correct answer number of points scored ,=\frac{3 y}{x}

As, it is given that number of correct answers is 3, and number of question is x, so total number of incorrect answer will be = x-3,

For, incorrect answer points scored will be =0

In Second test

For, seven correct answer number of points scored ,=\frac{7 y}{x}

As, it is given that number of correct answers is 7, and number of question is x, so total number of incorrect answer will be = x-7,

For, incorrect answer points scored will be =0

So, transforming the statement in terms of equation

Total number of points

   \frac{3y}{x}+\frac{7y}{x}=\frac{10y}{x}

Paul wanted to bring his family to the Children’s Museum. There was an exhibit with carnival rides. The tickets for each ride we
Nostrana [21]

We want to define and solve a linear equation to model the given case.

The answers are:

a) x = number of tickets, y = total cost.

b) y = $1.35*x + $6.35

We know that:

The tickets for each ride were $1.35 per ticket.

Paul purchased 30 tickets

He spent a total of $46.85 (on tickets and admission)

The cost for the 30 tickets is:

30*$1.35 = $40.50

a) Now we can define two variables:

y = total cost

x = number of tickets

b) the linear equation would be:

y = $1.35*x + P

Where P is the price of admission.

And we know that the total cost for 30 tickets is $46.85, then we have:

$46.85 = $40.50 + P

$46.85 - $40.50 = P = $6.35

So the admission price is $6.35

This means that the linear equation is:

y = $1.35*x + $6.35

c) Brief explanation, we have the variable y that represents the total cost, it is equal to the admission price (which we found) plus $1.35 times the number of tickets bought (x).

-3. Put the two equation equal to each other and solve. 
4x+18=2x+12
-2x=-2x 
2x+18=12 
-18=-18 
2x=-6 
2x/2=-6/2
