A Van can carry 13 students and a bus can carry 44 students.

<h3><u>Step-by-step explanation:</u></h3>

As given in the question number of students in each bus and each van carried same number of students.

Let the number of students in van be x.

Let the number of students in bus be y.

According to the question the equations will be

3x + 5y = 259  --------> Eqn. (1)

9x + 8y = 469 ---------> Eqn. (2)

On multiplying Eqn(1) by 3 and subtracting with Eqn(2) we get

9x + 15y - (9x+8y) = 777-469\\9x+15y-9x-8y = 308\\7y = 308\\

y = 44

On putting value of y in eq (1) we get

3x + 5 \times 44 = 259

3x + 220 = 259 \\3x = 259-220\\3x= 39

x=13

Therefore number of students in van is 13 and bus is 44.

Can anyone help out with the first question so I can get an idea with the others?
Oksanka [162]
As you can see, the first number line is divided into tenths (0.1, 0.2, 0.3). So, put 8.152 in between 8.1 and 8.2.

Then, the ends of the next number line should be 8.1 at the start, and 8.2 at the end. You keep going smaller to find the exact spot. So, move 5 places inwards and place the 8.153, between 8.15 and 8.16.

Afterwards, the ends of the last number line should be 8.15 and 8.16. Now, it is divided into thousandths. So, find the third spot. Now, it should be 8.153 correctly labeled.

25,000(4+3x) =125,000
Amanda [17]
To solve this equation, first we have to use the distributive property to eliminate the parentheses on the left side of the equation.

If done correctly, your simplified equation should be 

100,000 + 75,000x = 125,000

Next, we would subtract 100,000 from both sides, resulting in the equation

75,000x = 25,000

Finally, we would divide both sides of the equation by 75,000, resulting in your final answer of 

x= 25,000/75,000

However, many mathematics teachers ask for fractional answers to be simplified.  To simplify fractions, we first find the GCF of both numbers, and then divide both the numerator and the denominator by the GCF.

The GCF of 25,000 and 75,000 is 25,000.

So, in simplest form, your final answer is 

x=1/3
