To find the equivalent expression to 8n + 5n, you combine like terms by adding the coefficients of n, resulting in 13n.

The equivalent expression to 8n + 5n is found by combining like terms. Since both terms include the variable n, you can add their coefficients. To find the equivalent expression, you simply add the numbers in front of the n terms:

8n + 5n = (8 + 5)n = 13n.

So, the equivalent expression to 8n + 5n is 13n. This process is based on the distributive property which states that a(b + c) = ab + ac. In this case, we had a common factor of n which we factored out and then added the coefficients 8 and 5.

Final answer:

The equivalent expression is 13n.

Explanation:

The equivalent expression to 8n + 5n is 13n.

To find the equivalent expression, we simply combine the coefficients of n. In this case, 8n represents 8 times n and 5n represents 5 times n. Adding these two expressions together gives us 8n + 5n = 13n.

The Vertices of Rectangle are,A (2, 3), B(9, 3), C(9, -2), and D(2, -2).

Area of Rectangle = Length × Breadth

[tex]\text{Use Distance formula to find distance between two points}=\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2}}\\\\\text{Length}=\sqrt{(9-2)^2+(3-3)^2}=\sqrt{7^2}=7\\\\\text{Breadth}=\sqrt{(9-9)^2+(-2-3)^2}=\sqrt{(-5)^2}=\sqrt{5^2}=5[/tex]

So, Area of Rectangle = 7 × 5

                      = 35 square units

We need to divide the number of CDs sold, 3,467, by the number of days, 7

In order to estimate the quotient, we will use compatible numbers.

3,467 is close to 3,500

Remember: Compatible numbers are numbers that are close in value to the actual numbers, and which make it easy to perform mental arithmetic.

Some examples of compatible numbers when doing division are 400 and 10, 36 and 6, 2400 and 12, and 64 and 8

3,500 and 7 are compatible because when doing this division (3,500 ÷7 ), we can quickly divide 35  by 7 to get 5 and put two zeros at the end to get 500

3,500 ÷ 7 = 500  

About 500 CDs were sold each day

To compare the amount of yogurt in a 2 pound container and five 6-ounce containers, convert pounds to ounces. Then compare the measurements. To calculate how many yogurts can be bought for 5 pounds, divide 5 pounds by the price of 1 yogurt.

The equation that shows that the number increased by negative eight will be n + (-8) = 14. Hence, option C is correct.

Equations are mathematical expressions that have two algebras on either side of an equal (=) sign. The expressions on the left and right are shown to be equal to one another, demonstrating this relationship. L.H.S. = R.H.S. (left-hand side = right side) is a fundamental simple equation.

As per the data given in the question,

Let the number be x.

The number x is increased by negative 8 times which is equal to 14.

Then the equation according to the statement is,

n + (-8) = 14,

Therefore, this concludes that option C is correct.

The two lines are parallel with equal slopes, will never intersect, and have different y-intercepts, showing a constant vertical distance.

To draw a line through each point using the given slope, we will use the slope-point form of a line equation, which is [tex]\( y - y_1 = m(x - x_1) \)[/tex], where [tex]\( m \)[/tex] is the slope and [tex]\( (x_1, y_1) \)[/tex] is the point through which the line passes.

The slope given is [tex]\( \frac{1}{2} \)[/tex]. We have two points, [tex]\( (-2, 1) \)[/tex] and [tex]\( (4, -2) \)[/tex]. Let's calculate the equation of the line for each point.

For the point [tex]\( (-2, 1) \)[/tex]:

[tex]\[ y - 1 = \frac{1}{2}(x - (-2)) \][/tex]

[tex]\[ y - 1 = \frac{1}{2}(x + 2) \][/tex]

[tex]\[ y = \frac{1}{2}x + 2 \cdot \frac{1}{2} + 1 \][/tex]

[tex]\[ y = \frac{1}{2}x + 2 \][/tex]

For the point [tex]\( (4, -2) \)[/tex]:

[tex]\[ y - (-2) = \frac{1}{2}(x - 4) \][/tex]

[tex]\[ y + 2 = \frac{1}{2}x - 4 \cdot \frac{1}{2} \][/tex]

[tex]\[ y = \frac{1}{2}x - 2 - 2 \][/tex]

[tex]\[ y = \frac{1}{2}x - 4 \][/tex]

Now we have the equations for both lines, plot them on the graph to show the relationship between them. Let's proceed with plotting these lines.

(GRAPH IS GIVEN BELOW)

The graph shows two lines:

1. The red line passes through the point [tex]\((-2, 1)\)[/tex] and has a slope of [tex]\(\frac{1}{2}\)[/tex]. Its equation is [tex]\(y = \frac{1}{2}x + 2\)[/tex].

2. The blue line passes through the point [tex]\((4, -2)\)[/tex] and also has a slope of [tex]\(\frac{1}{2}\)[/tex]. Its equation is [tex]\(y = \frac{1}{2}x - 4\)[/tex].

Observing the two lines on the graph, you can notice the following points:

1. Both lines have the same slope of [tex]\(\frac{1}{2}\)[/tex], which means they are parallel to each other.

2. Because they are parallel, the two lines will never intersect each other.

3. The lines have different y-intercepts, which is consistent with parallel lines that are not coincident.

4. The difference in the y-intercepts 2 for the first line and [tex]\(-4\)[/tex] for the second line) corresponds to the vertical distance between the two lines.

The Miller's have 3/8 of their income left after setting aside amounts for fixed expenses and savings.

The millers budget 1/2 of their income for fixed expenses and 1/8 of their income for savings. Together, these fractions add up to 1/2 + 1/8 = 5/8 of their income. Calculating what's left of their income involves subtracting the total fraction used (5/8) from the whole (which in terms of fractions, is represented by 1). Hence:

1 - 5/8 = 3/8.

So, the Miller's have 3/8 of their income left after considering fixed expenses and savings.
