x=
Pls help and explain it in steps please!!!!
Answer:
x = 6
Step-by-step explanation:
Calculations:
2(x + 4) = 20 (Distribute)
2x + 8 = 20 (Subtract 8 from both sides)
2x = 12 (Divide by 2 from both sides)
x = 6
Verify:
2(10) = 20 (Correct)

The perimeter is 56.6 ft
Step-by-step explanation:
7.7 * 6 + 5.2 * 2
= 46.2 + 10.4
= 56.6 ft
does anyone know how to do this by solving with substitution
Answer:
Step-by-step explanation:
Question 1
System of equations is,
y = -6x -------(1)
y = -4x - 2 ---------(2)
Substitute the value of y from equation (1) to equation (2)
-6x = -4x - 2
-6x + 4x = -2
-2x = -2
x = 1
From equation (1)
y = -6(1)
y = -6
Question (2)
System of equations is,
-y = x --------(1)
3x + 5y = 20 ---------(2)
Substitute the value of x from equation (1) to equation (2)
3(-y) + 5y = 20
-3y + 5y = 20
2y = 20
y = 10
From equation (1)
-y = x
x = -10
Question (3)
System of the equations is,
y = -2x - 7 --------(1)
9x - 10y = 12 ----------(2)
Substitute the value of y from equation (1) to equation (2)
9x - 10(-2x - 7) = 12
9x + 20x + 70 = 12
29x = 12 - 70
29x = -58
x = -2
From equation (1)
y = -2(-2) - 7
y = 4 - 7
y = -3
how can you represent all of the solutions to systems of inequalities?
Answer:A closed, or shaded, circle is used to represent the inequalities greater than or equal to (≥) or less than or equal to (≤) . The point is part of the solution. An open circle is used for greater than (>) or less than (<). The point is not part of the solution. Solving" systems of linear inequalities means "graphing each individual inequality, and then finding the overlaps of the various solutions". So I graph each inequality, and then find the overlapping portions of the solution regions.Step 1: Line up the equations so that the variables are lined up vertically. Step 2: Choose the easiest variable to eliminate and multiply both equations by different numbers so that the coefficients of that variable are the same. Step 3: Subtract the two equations. Step 4: Solve the one variable system.

y varies directly as x, if y = 9, when x = -3, find x when y = -27
Answer:
9
Step-by-step explanation:
x Is -1/3 of y
-27x-1/3= 9
The value of x when y = -27 is 9.
y varies directly as x
Therefore,
y ∝ x
y = kx
where
k = constant of proportionality
Let's find k when y = 9 and x = -3
y = kx
9 = -3k
k = 9 / -3
k = -3
Let's find x when y = -27
y = kx
-27 = -3x
x = -27 / -3
x = 9

What is a graph?A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data. In discrete mathematics, and more specifically in graph theory.
A graph is a structure consisting of a set of objects, some of which are "related" in some way. The objects correspond to mathematical abstractions known as vertices, and each pair of related vertices is known as an edge.
1. The graph in option 1 is Neither. It is not discrete and continuous.
2. The graph in option 2 is discrete. The values of the data are not in a specific pattern.
3. The graph in option 3 is discrete. The values of the data are not in a specific pattern.

What is the slope & y-intercept for
y= -2x - 5 ?
Answer:
Slope = 2, and y intercept = -5
Answer:
The overall equation for slope-intercept is
y = mx + b
M would equal slope
B would be equal y-intercept.
So, judging from both equations now,
-2 is slope, while y-intercept is -5
If you are confused on why the y-intercept is -5 I will answer it for you. Have a good day ^-^

The measure of an exterior angle of a triangle is x. The measure of the adjacent interior angle is at least twice x. List three possible solutions for x.
Answer:
x=60°
x=48°
x=21°
Step-by-step explanation:
Inequalities
The sum of the exterior and the interior angle of a triangle is 180°.
The measure of an exterior angle of a triangle is called x, thus the interior angle is 180-x.
This angle is said to be at least twice x, thus:
180 - x ≥ 2x
Adding x:
180 ≥ 3x
Dividing by 3:
60 ≥ x
Swapping the inequality:
x ≤ 60°
The measure of x must be less or equal to 60°.
Three possible solutions are:
x=60°
x=48°
x=21°
