A set of equations is given below: equation e: m = 4n 1 equation f: m = 6n 8 which statement describes a step that can be used to find the solution to the set of equations? equation f can be written as m = 6(m − 1) 8. equation f can be written as m = 4(m − 8) 1. equation f can be written as 4n 1 = 6n 8. equation f can be written as n 1 = 6n 8.
The statement that describes a step to find the solution to the set of equations is the equation f can be written as 4n + 1 = 6n + 8
How to solve the equation?The system of equations is given as:
m = 4n + 1
m = 6n + 8
To solve the equation, we simply substitute 4n + 1 for m in the second equation.
So, we have:
4n + 1 = 6n + 8
Hence, the equation f can be written as 4n + 1 = 6n + 8

A wall in Alex and Carla Dinu's garden is to be built using brick that is 5 3/8 inches wide and a mortar joint that is 3/4
inch wide. Using the diagram, what is the height of the wall?
Answer: 29 7/8
Step-by-step explanation:
The height of wall will be 29.875 inch.
How to measure height of the wall?The height of the wall can be measured by the sum of total height of bricks and the height of mortar joint between the bricks.
According to question there is 4 mortar joint and 5 rows of bricks.
How to determine the no. of mortar joint?1 mortar joint is situated between 2 bricks. So, if the no. of bricks is n, then mortar joint between them will be n-1.
So, width of one mortar joint is= 3/4 inch
Width of 4 mortar joints = (3/4)*4=3 inch
width of one brick is= 5.375 inch
Width of 5 bricks = 5.375*5=26.875 inch
Height of the wall
= width of 4 mortar joints + width of 5 bricks
= 3+26.875
=29.875inch or 29 7/8 inch
Therefore, the height of wall will be 29.875 inch.

Write 2/7x(1.4x^2-3.5y) as a polynomial
Answer:
0.4x^3 - xy.
Step-by-step explanation:
2/7x(1.4x^2-3.5y) Distributing the2/7x over the parentheses:
= 2/7 * 1.4 x^3 - 2/7 *3.5xy
= 0.4x^3 - xy
The expression 2/7x(1.4x² - 3.5y) can be written as the polynomial (4/5)x³ - (10/7)xy.
What is a polynomial?A polynomial in mathematics is an expression made up of coefficients and indeterminates and involves only the operations of multiplication, addition, subtraction, and non-negative integer exponentiation of variables.
To write 2/7x(1.4x² - 3.5y) as a polynomial, we need to first simplify the expression inside the parentheses by distributing the 2/7x:
2/7x(1.4x² - 3.5y) = (2/7x)(1.4x²) - (2/7x)(3.5y)
Next, we can simplify each term by multiplying the coefficients:
2/7x(1.4x² - 3.5y) = (4/5)x³ - (10/7)xy
Thus, 2/7x(1.4x² - 3.5y) can be written as the polynomial (4/5)x³ - (10/7)xy.

How to solve 16x-8y=72
**Kind note:
Since there are two variables in one equation, it is impossible to determine a specific value for x and y. (Unless the trial-and-error method is used).
How to determine the value of x using the equation (16x - 8y = 72)?
To determine the value of "x", we need to isolate the x-variable on one side. The value (or expression) obtained on the opposite side of the x-variable will be the value of x.
How to determine the value of y using the equation (16x - 8y = 72)?
To determine the value of "y", we need to isolate the y-variable on one side. The value (or expression) obtained on the opposite side of the y-variable will be the value of y.
Determining the x-variable:
⇒ 16x - 8y = 72
⇒ 16x = 72 + 8y [Adding 8y to both sides of the equation]
⇒ 16x/16 = (72 + 8y)/16 [Dividing 16 to both sides of the equation]
⇒ x = 9/2 + y/2 [Simplifying both sides of the equation]
⇒ x = (9 + y)/2 [Combining the denominators]
Determining the y-variable:
⇒ 16x - 8y = 72
⇒ 16x - 8y - 16x = 72 - 16x [Subtracting 16x both sides of the equation]
⇒ -8y = 72 - 16x [Simplifying both sides of the equation]
⇒ -8y/-8 = (72 - 16x)/-8 [Dividing -8 to both sides of the equation]
⇒ -8y/-8 = 72/-8 - 16x/-8
⇒ -8y/-8 = -72/8 + 16x/8
⇒ y = -9 + 2x [Simplifying both sides of the equation]
First simplify it to suitable form of slope intercept then you can get values
16x-8y=722x-y=9y=2x-9The pairs are
(1,-7)(2,-5)(3,-3)(4,-1)(5,1)And so on

Answer:
(2, -7)
x = 2
y = -7
Step-by-step explanation:
Let's solve this system of equations by elimination.
Start by multiplying the first equation by 2:
[tex]2(4x)+2(3y)=2(-13)\\8x+6y=-26[/tex]
Next, multiply the second equation by 3:
[tex]3(-5x)+3(2y)=3(-24)\\-15x+6y=-72[/tex]
Notice that both equations now have a "6y", meaning we can subtract both equations and thereby eliminating the variable "y" from the equation:
[tex]8x+6y-(-15x+6y)=-26-(-72)\\8x+6y+15x-6y=-26+72\\23x=46[/tex]
Divide both sides by 23
[tex]x=2[/tex]
Substitute 2 for "x" to solve for "y".
[tex]4x+3y=-13\\4(2)+3y=-13\\8+3y=-13[/tex]
Subtract 8 from both sides:
[tex]3y=-21[/tex]
Divide both sides by 3:
[tex]y=-7[/tex]
Therefore the answer is:
[tex](x, y)=(2, -7)[/tex]
Additional Comments:
Note that we can only divide, subtract, multiply, or add both sides of the equation by the same quantity due to the Division, Subtraction, Multiplication, or Addition Property of Equality. These properties state that if you divide/subtract/multiply/add one side of the equation by one quantity, you must do the same to the other side of the equation so that it remains an equation.

Answer:
(200, 120)Step-by-step explanation:
Given system
x - y = 803/5 = y/xSolve it by substitution
y = 3/5(x)y = x - 80Find the value of x
3/5(x) = x - 80x - 3/5(x) = 802/5(x) = 80x = 80*5/2x = 200Find the value of y
y = 3/5(200)y = 120Answer:
x = 200
Step-by-step explanation:
Given system of equations:
[tex]\begin{cases}x-y=80\\\\\dfrac{3}{5}=\dfrac{y}{x} \end{cases}[/tex]
Rearrange the second equation to make y the subject by multiplying both sides by x:
[tex]\implies \dfrac{3}{5} \cdot x=\dfrac{y}{x} \cdot x[/tex]
[tex]\implies y=\dfrac{3}{5}x[/tex]
Substitute this into the first equation and solve for x:
[tex]\implies x-\left(\dfrac{3}{5}x\right)=80[/tex]
[tex]\implies \dfrac{2}{5}x=80[/tex]
[tex]\implies \dfrac{2}{5}x \cdot 5=80 \cdot 5[/tex]
[tex]\implies 2x=400[/tex]
[tex]\implies \dfrac{2x}{2}=\dfrac{400}{2}[/tex]
[tex]\implies x=200[/tex]
Therefore, the value of x is 200.
If you want to find the value of y, simply substitute the found value of x into the first equation and solve for y:
[tex]\implies 200-y=80[/tex]
[tex]\implies 200-y+y=80+y[/tex]
[tex]\implies 200=y+80[/tex]
[tex]\implies 200-80=y+80-80[/tex]
[tex]\implies 120=y[/tex]
[tex]\implies y=120[/tex]
