Answer:

3(x+2)=42

Step-by-step explanation:

So lets go over what we know:

There are 3 large pizzas

Each pizza has a addition cost of 2 dollars

The total cost is 42 dollars

We need to find the cost per pizza.

Now lets piece together our equation.

We know that the pizzas equal 42 dollars so we can immediately put 42 on the opposite side of the equal side:

=42

We also know that each of the 3 pizzas cost 2 dollars. This would go on the left side of the equation:

6=42
Now, we know x is the amount of pizzas. There are 3 pizzas, or in other words, 3x. We can add this to the left side of the equation, because the 3 pizzas plus the 6 dollars equals the total of 42 dollars:

3x+6=42

There are no answers above that look like this, however. This is because we have to factor the left side of the equation.

A factor of both 3 and 6 is 3. So we can factor out 3 and we get:

3(x+2)=42

This looks like the first answer!
Hope this helps! :3

Answer:

A. 30

Step-by-step explanation:

The interquartile range for a box and whiskers plot, is the value from the right side of the box minus the value of the left side of the box.

In this case at the far right side of the box it is at 130, at the far left side of the box it is at 100.

130-100=30

A sample of small bottles and their contents has the following weights (in grams): 4, 2, 5, 4, 5, 2, and 6. What is the sample v
Inessa05 [86]

Answer:

What is the sample variance of bottle weight 2.33

Step-by-step explanation:

First find the mean. The mean of the bottle weight is obtained by taking the ratio of the sum of ages and total number of ages.

Mean = (4+2+5+4+5+2+6) / 7

          = 28 / 7

          = 4

Sample Variance = \frac{\left[\begin{array}{ccc}(4-4)^{2} +(2-4)^{2} +\\(5-4)^{2} + (4-4)^{2} +\\(5-4)^{2} + (2-4)^{2} +\\(6-4)^{2}\end{array}\right]}{7-1}

                             =\frac{0+4+1+0+1+4+4}{6}

                             = 2.33

The graph shows a proportional relationship Which equation matches the graph
tankabanditka [31]

The equation for the graph passing through the points (0, 0) and (3, 12) is y = 4x.

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

From the graph, using the points (0, 0) and (3, 12):

y - 0 = [(12 - 0)/(3 - 0)](x - 0)

y = 4x

The equation for the graph passing through the points (0, 0) and (3, 12) is y = 4x.
