-(7-2x)+7=-7 help please
Answer:
X = -7/2
Step-by-step explanation:
Answer:
x = -7/2
Step-by-step explanation:
-(7-2x)+7=-7
-7 -7
Start by subtracting -7 from both sides.
-(7-2x) = -14
Divide both sides by -1 to eliminate the negatives.
-(7-2x) = -14
--------- -------
-1 -1
Simplify.
7-2x = 14
Subtract -7 from both sides.
-2x = -7
Divide both sides by -2
-2x = -7
----- ----
-2 -2
x= -7/2
Check if -7/2 by plugging it back into the equation: (-7/2 = -3.5)
-(7-2(-3.5))+7 = -7

Answer:
3x-y=-13
Step-by-step explanation:
y-3x=13
Use the commutative property to reorder the terms
-3x+y=13
Change the signs on both sides of the equation
3x-y=-13
Solve for j.
-12 + 6j = 7j
Answer:
[tex]\large\boxed{j = -12}[/tex]
Step-by-step explanation:
-12 + 6j = 7j
Subtract 6j from both sides of the equation
[tex]\large\boxed{j = -12}[/tex]
This kind of equation can usually be solved by moving the numbers to the opposite side of the equation as the variables.
Hope this helps :)

please helppp The correct equation is S=2r+7 verify this equation matches your table for r=1 r=2 and r=3
Answer:
Step-by-step explanation:
Part (A).
Row Number of seats
1 9
2 11
3 13
4 15
5 17
6 19
7 21
(B). Jonathan models the equation for the pattern of number of seats as,
S = 7r + 2
Where S = number of seats in every row 'r'
For r = 1,
S = 7(1) + 2 = 9
Models for row 1.
For r = 2,
S = 7(2) + 2 = 16
Not correct.
For r = 3,
S = 7(3) + 2 = 23
Not correct.
Therefore, this equation doesn't work for the rows above the first row.
(C). Correct equation is,
S = 2r +7
For r = 1,
S = 9
For r = 2,
S = 4 + 7 = 11
For r = 3,
S = 6 + 7 = 13
Therefore, this equation works for all the rows.
(D). Number of seats in 15th row = 2(15) + 7 = 37 (For r = 15)
(E). 91 = 2r + 7
2r = 91 - 7
2r = 84
r = 42
Therefore, in 42nd row number of seats = 91

Simplify: (5x2 - 3x - 4)(3x - 7) A. 15x3 - 44x2 + 9x - 28 B. 15x3 - 44x2 + 9x + 28 C. 15x3 + 26x2 - 33x - 28 D. 15x3 - 26x2 - 33x + 28
Answer:
A. 15x^3 -44x^2 +9x +28
Step-by-step explanation:
(5x^2 -3x -4)(3x - 7)
first, distribute by multiplying the terms in each parenthesis with each other:
(5x^2 * 3x) - (3x * 3x) - (4 * 3x) - (5x^2 * 7) + (3x * 7) + (4 * 7)
simplify:
15x^3 -35x^2 -9x^2 +21x -12x +28
Now combine like terms:
15x^3 -44x^2 +9x +28
A ballroom is 60 ft long and 30 ft wide. Which of the following formulas is the correct formulas to determine the perimeter of the ballroom. a. P=2+60+2+30 b. P=60x30 c. P= 30x 30 + 60 x60 d. P= 2 x 60 + 2x 30
Answer:
The answer is D: 2 x 60 + 2 x 30
Step-by-step explanation:
The perimeter is the lengths of all the sides of a shape combined. Therefore, 60 is one side and 30 is the other side. Since the opposite sides are equal, there are two sides that equal 60 and two sides that equal 30.
So, 60 + 60 + 30 + 30.
60 + 60 = 60 x 2
30 + 30 = 30 x 2
Therefore, the answer is 60 x 2 + 30 x 2.

Answer:
x = 12/13
BC = 140/13
Step-by-step explanation:
If A is the mipoint of BC, then AB is half of BC.
AB = BC / 2
8x − 2 = (3x + 8) / 2
16x − 4 = 3x + 8
13x = 12
x = 12/13
BC = 3x + 8
BC = 3 (12/13) + 8
BC = 36/13 + 104/13
BC = 140/13
What is -5(-3r-3)=75
Answer:
r = 4
Step-by-step explanation:
-5(-3r - 3) = 75
Divide both sides by -5.
-3r - 3 = -15
Add 3 to both sides.
-3r = -12
Divide both sides by -3.
r = 4
