Answer:
[tex]x=-2[/tex]
Step-by-step explanation:
[tex]2x + 4 = 0[/tex]
Subtract 4 from both sides:-
[tex]2x+4-4=0-4[/tex]
[tex]2x=-4[/tex]
Divide both sides by 2:-
[tex]\frac{2x}{2}=\frac{-4}{2}[/tex]
[tex]x=-2[/tex]

Choose the equation below that is equivalent to 4(x-7) -2(x+1) = -10
A. -2(x - 7) + (x + 1) = -5
B. -2(x - 7) + (x + 1) = 5
C. 2(x - 7) + (x + 1) = -5
D. 2(x - 7) - (x + 1) = 5
Answer:
B
Step-by-step explanation:
4 (x - 7) - 2 (x + 1) = 10
x = 10
B. -2 (x - 7) + (x + 1) = 5
x = 10
your equation is equivalent to B!

AC = 8, AB = 2x + 20, and BC = 2x + 24. Find x.
Answer:
Answer: x is -9
Step-by-step explanation:
If it's a line AC with a point B between;
AC = AB + BC
substitute in terms of x :
[tex]8 = (2x + 20) + (2x + 24)[/tex]
group x terms in a same bracket, and constants in their bracket
[tex]8 = (2x + 2x) + (20 + 24) [/tex]
operate the brackets:
[tex]8 = 4x + 44[/tex]
subtract 44 from both sides:
[tex]8 - 44 = (4x + 44) - 44 [/tex]
simplify:
[tex] - 36 = 4x[/tex]
divide all sides by 4:
[tex] \frac{ - 36}{4} = \frac{4x}{4} \\ \\ x = - 9[/tex]

The appropriate and equivalent expression is listed below ;
(3 × 4) + (3 × 7) = 3(4 + 7) (5 × 9) - (5 × 6) = 5(9 - 6)(32 + 16) = 48 = 8(4 + 2)4(100 - 3) = 97 × 4 7(60+6) = 66 × 7(3 × 4) + (3 × 7)
Factorize :
Since 3 is common to both sides :
(3 × 4) + (3 × 7) = 3(4 + 7)
(5 × 9) - (5 × 6)
Factorize :
5 common to both sides :
(5 × 9) - (5 × 6) = 5(9 - 6)
(32 + 16) = 48
A common multiple of both 32 and 16 = 8
(8 × 4) = 32
(8 × 2) = 16
Hence,
(8 × 4) + (8 × 2) = 48
(8 × 4) + (8 × 2)
Factorize :

Answer:
Step-by-step explanation:
This is segment addition in Geometry. Picture a straight line with endpoints A and C. B is a point stuck somewhere between them. The length of AC then is equal to the length of AB plus the length of BC. In algebraic terms:
AC = AB + BC. Filling in from the problem:
81 = 2x + 1 + 6x and combine like terms:
81 = 8x + 1 and subtract over the 1:
80 = 8x and divide by 8 to find
x = 10.

How many repeating digits are in the smallest group of repeating digits in the decimal equivalent of the fraction shown?
745/999
If x = 745/999, then
999x = 745
1000x - x = 745
This equation tells us that the fractional part of 1000x and x cancel upon subtracting. This means the block of repeating digits must be 3 digits long.
To verify this, suppose we write x = 0.yyy… , where y consists of 3 digits. Then
1000x = y.yyy…
1000x - x = y.yyy… - 0.yyy…
999x = y
x = y/999
which means y = 745.
Answer:
3 digits

-2x+9y=-9
9x-2y=2
Step by step needed asap
Answer:
(0,-1) I could be wrong
Step-by-step explanation:
Answer:
Step-by-step explanation:
-2x+9y=-9 (solve for x)
-2x= -9y-9
X = - 9y/-2 - - 9/2. X = 9y/2 + 9/2
9(9/2y+9/2)-2y=2
81y/2 + 81/2 - 2y = 2
81y/2 - 2y = 2 - 81/2. 81/2 - 2 = 77/2 and -81/2 +2 = -77/2
77/2 y = - 77/2
y = (-77/2)/(77/2)
y = - 1

Find the sales tax and total cost of a Sony Playstation that costs $151.99. The tax rate is 4%. Round your answer to the nearest cent.
Total would be $158.07
To calculate slaes tax and total cost, take the price (151.99) and multiply by tax rate, then add them together.
4%= .04
So Price (151.99) times tax(.04) would be 6.0796.
We're not finished, because that is just the tax.
Add them together, 151.99+6.0796 = 158.0696
Round to the nearest cent, so $158.07

Find the value of 9w + 1 given that -5w -5 = 5
Answer:
-17
Step-by-step explanation:
First, let's see what the value of w is, by solving -5w - 5 = 5.
-5w - 5 = 5 Add 5 on both sides.
-5w = 10 Divide -5 on both sides.
w = -2
Now, we know that w is equal to -2, let's plug it in to find the value.
9(-2) + 1 Distribute.
-18 + 1 Add.
