Answer:
i only know 1. is 8
and also 5. 0= −3
Step-by-step explanation:
Answer and Step-by-step explanation:
7(x-5)=x+13
Distribute the 7, then solve for x.
7x - 35 = x + 13
6x = 48 (Added 35, subtracted x)
x = 8 (Divided by 6)
One solution
-6x=-5(x-1)-x
Distribute the -5, then combine like terms. Solve for x.
-6x = -5x + 1 - x (negative times negative equals positive)
-1 = 0 (Added 6x, subtracted the x from 1x, subtracted 1)
No solution
-4(x-2)=-2(x-17/2)
Distribute the -4 and -2, then solve for x.
-4x + 8 = -2x + 17 (negative times negative equals positive) (the 2's cancel out to be 17)
-9 = 2x (Added 4x, subtracted 17)
-9/2 = x
One solution
3 - 4x + 5 = 2(8 - 2x)
Distribute the 2, combine like terms. Solve for x.
8 - 4x = 16 - 4x
0 = 8
No solution
2x + 3= +2x
3 = 0
No solution
2x+3=2x+5
0 = 2
No solution
3x+9=2.5x+14
0.5x = 5
x = 10
7(x-4)=4x+5
7x - 28 = 4x + 5
3x = 33
x = 11
One solution
5x-20=-7x-20
12x = 0
x = 0
One solution
3(2x+1)-4x=2x+3
6x + 3 - 4x = 2x + 3
2x + 3 = 2x + 3
0 = 0
Infinite solutions (The reason why this one is infinite is because if you were to plug in any value for x, the result will equal itself, like the 0 = 0.

Answer:
B
Step-by-step explanation:
You would have to multiply the prices by how many pizzas were sold. So you would have to 9.99 by 39 since that is the price for the small pizza's, and so on.
Write an equation to match this graph.
Answer:
y = x + 7
Step-by-step explanation:
This is a linear equation graph because the line is straight and it is going at a constant rate. You can just either add or subtract the dependent event or the y variable. So I use the linear equation y = mx + b.
Use the y2 - y1 / x2 - x1 to find the slope. The slope is basically m. You can use any coordinate for this.
I will use (2, 9) and (3,10) as the coordinates for an example.
So y2 = 10
y1 = 9
x2 = 3
x1 = 2
10 - 9 / 3 - 2 = 1/1 = 1
1 is the same thing as x.
So the slope is x.
Now in order to find b(or the whole number on the far right), you use one of the x and y coordinates.
For an example I will use (5, 12)
Now all I do is use the formula y = mx + b
y = 12
x = 5
m = 1. M is the same thing as slope.
b is what I must find out.
So I write 12 = 1(5) + b
12 = 5 + b
Then you subtract 5 from 12
and you will get 7.
12 - 5 = 7
The b or the y intercept equals 7.
So the equation for this graph is y = x + 7
Simple bro! The hard part was the explanation.
The equation for the line is y=x+7
What is the solution to a linear equation?The solution of a linear equation is defined as the points, in which the lines represent the intersection of two linear equations. In other words, the solution set of the system of linear equations is the set of all possible values to the variables that satisfies the given linear equation.
Given here, the points on the line are (2,9) , (3,10) , (4,11) , (5,12) , (6,13)
Let's assume the the equation of the line is y=x+7 then putting on the points on the equation we get
(2,9) 9=2+7
(3,10) 10=3+7
Similarly the equation holds good for all the points in the graph.
Hence, The equation for the line is y=x+7

Here is a balanced hanger diagram. Each triangle weighs 2.5 pounds, each circle weighs 3 pounds, and x represents the weight of each square.
Select all equations that represent the hanger.
D. 2x+2.5=3
B. 2x=0.5
E. 4x+2.5+2.5+3+3=2x+2.5+3+3+3
C. 4x+5+6=2x+2.5+6
A. x+x+x+x+11=x+11.5
Option E will be the correct option.
Condition for the balanced hanger,
Both the sides of the hanger will be balanced if weights on both the sides of the hanger must be equal.Weights on left side = 4(weight of one square) + 2(weight of one triangle) + 2(weight of one circle)
Weights on right side = 2(weight of one square) + 1(weight of one triangle) + 3(weight of one circle)
Since, hanger is balanced,
Weights on the left side = Weights on the right side
4(weight of one square) + 2(weight of one triangle) + 2(weight of one circle) = 2(weight of one square) + 1(weight of one triangle) + 3(weight of one circle)
4x + 2(2.5) + 2(3) = 2x + 2.5 + 3(3)
4x + 2.5 + 2.5 + 3 + 3 = 2x + 2.5 + 3 + 3 + 3
Therefore, Option E will be the answer.
