Answer:
x = -9.8
Step-by-step explanation:
6(x+7.8) =−12
Divide each side by 6
6/6(x+7.8) =−12/6
(x+7.8) =−2
Subtract 7.8 from each side
x+7.8-7.8 = -2-7.8
x = -9.8
This expression of yours is problematic in that it's difficult to know which math operations are intended and in which order. In <span>x/2 x-2/4 x-2/2 , which part of the expression is in the numerator, and which in the denominator?
x shows up 3 times. Apparently you meant "the variable x" in "x/2." What about the next "x?" Did you type that in to indicate multiplication or is that "x" a variable also? I think you catch my drift: Your post will need some editing before your readers can understand what you want to do here.
Suppose I interpret your </span><span>x/2 x-2/4 x-2/2 to mean the following:
( x/2 )
---------- * (x-2/2). If that wasn't your intent, please fix it.
x - 2/4
If this interpretation is correct, then you have
x(x-1) 2x(x-1)
---------------- = ------------. If not, please fix it. This rational function
x-1/2 2x -1 cannot be reduced.</span>
Answer:
Simplifying
5(x + 9) = 5x + 45
Reorder the terms:
5(9 + x) = 5x + 45
(9 * 5 + x * 5) = 5x + 45
(45 + 5x) = 5x + 45
Reorder the terms:
45 + 5x = 45 + 5x
Add '-45' to each side of the equation.
45 + -45 + 5x = 45 + -45 + 5x
Combine like terms: 45 + -45 = 0
0 + 5x = 45 + -45 + 5x
5x = 45 + -45 + 5x
Combine like terms: 45 + -45 = 0
5x = 0 + 5x
5x = 5x
Add '-5x' to each side of the equation.
5x + -5x = 5x + -5x
Combine like terms: 5x + -5x = 0
0 = 5x + -5x
Combine like terms: 5x + -5x = 0
0 = 0
Solving
0 = 0
Couldn't find a variable to solve for.
This equation is an identity, all real numbers are solutions
Step-by-step explanation:
Answer:
70 1/5 inches or 70.2
Step-by-step explanation:
9x12 is 108 inches
108 divided by 2 is 54 inches
1 inch for every 54 inches
1.3x 54 is 70.2
Question: Which situation is represented by 
?
Option A: Melanie equally shares 25 meters of paper to create 9 banners
Option B: Quill gives way 9 baseball cards from a pack of 25 cards.
Option C: George invites 25 kids and 9 adults to his birthday party.
Option D: Becca create 9 rows with 25 buttons.
Answer:
Solution:
Option A: Melanie equally shares 25 meters of paper to create 9 banners.
The fraction is .
Option B: Quill gives way 9 baseball cards from a pack of 25 cards.
The fraction is 
Option C: George invites 25 kids and 9 adults to his birthday party.
Here, 25 + 9.
Option D: Becca create 9 rows with 25 buttons.
Here, 9 × 25.
Hence the answer is Option A: Melanie equally shares 25 meters of paper to create 9 banners.
