In the first week of July, a record 1,040 people went to the local swimming pool. In the second week, 105 fewer people went to

lesantik [10]

Answer:

The percentage of people going to the people in week 4 compared to week 1 decreased by 25%.

Step-by-step explanation:

Week 1: 1,040 people

Week 2: 105 fewer people

1040 - 105 = 935 people

Week 3: 135 more people

935 + 135 = 1070 people

Week 4: 290 fewer people

1070 - 290 = 780 people

So, there were 260 fewer people, going to the pool in those 4 weeks compared to week 1.

Now, we must find the percentage change.

x/100 = 780/1040

Cross multiply.

1040x = 78000

Divide both sides by 1040 to leave x by itself on one side.

x = 78000/1040

x = 75%

This means only 75% of the total people from week one were going to the pool in week four. Therefore, there was a 25% decrease in the number of people who went to the pool over these four weeks.

Solve the following system of equations. 3x + 2y - 5 = 0 x = y + 10 Make sure there are NO SPACES in your answer. Include a comm

murzikaleks [220]

ANSWER

The solution to the system is

$x=5,y=-5$

EXPLANATION

The system of equations are:

$3x + 2y - 5 = 0 - - (1)$

and

$x = y + 10 - - (2)$

We put equation (2) in to equation (1) to get,

$3(y + 10) + 2y - 5 = 0$

We expand the parenthesis to obtain,

$3y + 30 + 2y - 5 = 0$

We group like terms to obtain,

$3y + 2y + 30 - 5 = 0$

$5y + 25 = 0$

This implies that,

$5y = - 25$

We divide through by 5 to get

$y = - 5$

We substitute the value of y in to equation (1) to get,
$3x + 2( -5 ) - 5 = 0$

$3x - 10- 5 = 0$

This implies that

$3x = 15$
We divide both side by 3 to get,

$x = 5$
