(x + 7)/-3 = 2
Multiply by -3
(x+7) = -6
Subtract 7
x = -13
The number is -13
We can solve for both x and y of System A and B to compare the values of x.
System A. Multiply by 4 the first equation and add both equations,
12x + 8y = 12
+ -2x - 8y = -1
We will be left with equation,
10x = 11
The value of x is 11/10
System B. Multiply the first equation by -2 and add the equations,
2x + 28y = -2
+ -2x - 8y = -1
We will be left with 20y = -3. Substitute the value of y to any of the equations. This gives a value of x equal to 11/10.
The answer therefore is that both systems will have the same value of x's.
I think it would be; maximum 25, minimum -15
Answer:
4 gal 12 pt
Step-by-step explanation:
1 gal + 3 gal = 4 gal
5 pt + 7 pt = 12 pt

AB and EF are the first two letters of ABCD and EFGH respectively. Therefore, these two sides correspond and pair up. They are the horizontal sides
AB = 4
EF = 8
Divide the two values
AB/EF = 4/8 = 1/2 = 0.5
We will use this value later so keep it in mind.
----------------------------------------
The sides AD and EH also pair up (and correspond). This is because the letters A & D are the first and last letters of ABCD. Same applies for E & H being the first and last letters of EFGH
AD = 2
EH = 6
Divide: AD/EH = 2/6 = 1/3 = 0.33 approx
Since we did not get 1/2 = 0.5 like we did above, this means that the sides are not in proportion to one another. Meaning that the rectangles are not similar.
So the equation AB/EF = AD/EH, which turns into 4/8 = 2/6, is not a true equation.

<h3>Answer: The rectangles are <u>not</u> similar </h3>
