What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
6 x 4 =( x 4) + (3 x 4)
Now, split 6 as two equal quantities
6 = 3+ 3
So, 6 x 4 =24
( 3x 4) + (3 x 4)
= 12+ 12
= 24
Hence, LHS = RHS.

Answer:
50$+40$
40$+50$
Step-by-step explanation:
An expression to represent the total cost for photography in a wedding in two different ways are 50+40x+15y and 50+40p+15a.
What is an expression?An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.
Given that, wedding photographer and their assistant work together to photograph weddings.
$50 is sitting fee, $50 sitting fee, $40 per hour for photographer's time and $15 per hour for assistants time.
Let the number of hours photographer spent be x and the number of hours assistants spent be y.
So, the total cost for photography
50+40x+15y
Let the number of hours photographer spent be p and the number of hours assistants spent be a.
50+40p+15a
Therefore, an expression to represent the total cost for photography in a wedding in two different ways are 50+40x+15y and 50+40p+15a.

Find the length of MN:

Hi!
So, first, let's just form the equation:
We know that all the side lengths equal 12 cm.
So the equation will be:
5 + 3 + x = 12
The answer you put in the box is:
5 + 3 + x
To find the value of x, we just solve this equation:
5 + 3 + x = 12
Combine like terms:
8 + x = 12
Same to both sides:
x = 12 - 8
x = 4
I hope this helped, let me know if you have any questions.

Find an equation of the line with the slope m=−1/8 that passes through the point (−5,0). Write the equation in the form Ax+By=C.
Answers
Answer:
x+8y= -5
Step-by-step explanation:
1) the required equation of the line has an slope-interception form:
y=mx+i, where m - slope, i - interception.
2) if the given point belongs to the required line, then it is possible to substitute its coordinates into the equation, then:
0=m*(-5)+i; ⇔-5m+i=0;
3) if the slope m= -1/8, then
-5*(-1/8)+i=0, ⇒5/8+i=0; ⇒ i= -5/8.
4) finally, the required equation is (m= -1/8; i= -5/8):
y= (-1/8)*x-5/8; ⇔ x+8y= -5.

suppose that the population of deer in a state is 16,000 and is growing 1%each year Predict population after 6 years
Answers
Answer:
16984
Step-by-step explanation:
Given
[tex]a = 16000[/tex] ---- Initial
[tex]r = 1\%[/tex] --- rate
Required
Determine the population after 6 years
To do this, we make use of the following exponential function
[tex]f(x) = a(r+1)^x[/tex]
Substitute values for a and r
[tex]f(x) = 16000(1\%+1)^x[/tex]
Express 1% and decimal
[tex]f(x) = 16000(0.01+1)^x[/tex]
[tex]f(x) = 16000(1.01)^x[/tex]
The population after 6 years is:
Substitute 6 for years
[tex]f(6) = 16000(1.01)^6[/tex]
[tex]f(6) = 16984.3224096[/tex]
[tex]f(6) = 16984[/tex] -- approximated

Shira's math test included a survey question asking how many hours students spent studying for the test. The scatter plot below shows the relationship between how many hours students spent studying and their score on the test. A line was fit to the data to model the relationship.
Answers
Answer:
Part 1) Option B. y = 10x + 45
Part 2) The score is 95
Step-by-step explanation:
Linear equation that best describes the given model
Let
x ---> number of hours students spent studying
y ---> their score on the test
Looking at the line that was fit to the data to model the relationship
The slope is positive
The y-intercept is the point (0,45)
For x=1, y=55 ----> point (1,55)
Find the slope
The formula to calculate the slope between two points is equal to
substitute the points (0,45) and (1,55)
Find the equation of the line in slope intercept form
we have
substitute
Part 2) Estimate the score for a student that spent 5 hours studying.
For x=5 hours
