Mr. Henderson paid a total of $98.40 for phone service and $79.20 for garbage pickup last year. To find his average cost per month for these two services, we need to divide the total amount he paid by the number of months in a year.
Since there are 12 months in a year, we can divide the total amount Mr. Henderson paid for phone service and garbage pickup by 12 to find his average cost per month. This is calculated as follows:
Average cost per month = (98.40 + 79.20) / 12
Average cost per month = 177.60 / 12
Average cost per month = $14.80
Therefore, Mr. Henderson's average cost per month for phone service and garbage pickup last year was $14.80. This means that, on average, he paid about $14.80 per month for these two services.

The value of a for system ax + 12y = −6, 2x − 6y = 4 having no solution is a = -4.
What is the equation?Equation: A statement that two variable or integer expressions are equal. In essence, equations are questions, and the motivation for the development of mathematics has been the systematic search for the answers to these questions.
Given:
ax + 12y = −6
2x − 6y = 4
Calculate the value of a by using the condition of no solution of the system given below,
[tex]a_1 / a_2 = b_1 / b_2 \neq c_1/c_2[/tex]
So, a₁ / a₂ = b₁ / b₂
a / 2 = 12 / (-6)
a / 2 = - 2
a = -4
And -4 / 2 ≠ -6 / 4
Therefore, the value of a for system ax + 12y = −6, 2x − 6y = 4 having no solution is a = -4.

If 400 m long fencing wire is required to surround a square flower garden 2 times, find the length of the garden. the Links Book 6 Approved by CDC
Answer:
Length (L) = 50 m
Step-by-step explanation:
Given information,
→ 400 m long fencing wire is required to surround square flower garden 2 times.
Now the fence taken for 1 time,
→ 400 ÷ 2
→ 200 m
Formula we use,
→ P = 4 × L
[Perimeter of square]
Then the length of the garden is,
→ P = 4 × L
→ 200 = 4L
→ 4L = 200
→ L = 200/4
→ [ L = 50 m ]
Hence, length of garden is 50 m.
If the perimeter of RSTU is 72 and RV = 16,
find RT and UV
A diagram is provided, on which R S T U's perimeter is 72 and R V's is 16, RT= 32 and UV ≈ 8.2.
How to find the perimeter calculation?A diagram is provided, on which R S T U's perimeter is 72 and R V's is 16.
Finding R T and U V is our goal.
First, let's assume that the figure RSTU is a rhombus since its perimeter and one-half of a diagonal's length are both provided. RT is the result of adding the segments RV and VT.
RT=RV + VT
We are informed that the RV is sixteen. If RV and VT are congruent, then V T equals 16. So:
R T = 16 + 16 = 32
In order to determine the UV length, we must first determine the RU length. Since a rhombus's sides are the same length, we can divide its perimeter by four to determine
RU= Perimeter/ 4
If we simplify and replace Perimeter with 72, we get:
RU = 72 / 4
RU =18
Since UB is a member of the right triangle RUV created by the intersection of the diagonals, we can now use the Pythagorean theorem to determine its length. So:
U V²+ R V² = RU²
If R V = 16 and R U = 18, we obtain:
U V² + 16 ²= 18²
By way of summary, we have:
U V² + 256 = 324
U V² + 256 − 256 = 324 − 256
√ UV = √ 68
UV = 8.2462
UV ≈ 8.2
Our recommendations are as follows:
RT= 32
UV ≈ 8.2.

The number of cars in a number of cities shows a positive correlation to the population of the respective city. Can it be inferred that an increase of cars in a city leads to an increase in the population?
Answer: No
A correlation is a relationship between two variables that tend to move in the same direction. Therefore, a positive correlation will describe two variables that increase together. However, correlation does not always equal causation, and in this case, this conclusion cannot be made. A more probable explanation is that there is some third variable causing an increase in population, so more people are buying more cars, not the other way around.

how to write the equation of the line with m = –1 and Passes point (4, 5) in Slope –Intercept Form.
Hello,
The slope-intercept form of a linear equation is:
y = mx + b
where m is the slope of the line and b is the y-intercept, which is the point where the line crosses the y-axis.
To write the equation of the line with slope m = -1 that passes through the point (4, 5), you can use the point-slope form of a linear equation, which is:
y - y1 = m(x - x1)
where (x1, y1) is a point on the line and m is the slope of the line. Plugging in the values, we get:
y - 5 = -1(x - 4)
This simplifies to:
y - 5 = -x + 4
Finally, we can rearrange the terms to put the equation in slope-intercept form:
y = -x + 9
This is the equation of the line with slope m = -1 that passes through the point (4, 5).

What is the scale factor?
The ratio of the scale of an original thing to a new object that is a representation of it but of a different size is known as a scale factor (bigger or smaller). For instance, we can increase the size of a rectangle with sides of 2 cm and 4 cm by multiplying each side by, let's say, 2.
13.5 / 9 = 1.5
9 * 1.5 = 13.5 \s12 * 1.5 = 18
You have a scale factor of 1.5. (because if u multiply 1.5 by the original shape, u get the new shape)
JKLM ~ WXYZ
