Answer:
x = 1/2
Step-by-step explanation:
2x + 3 = 4x + 2
-2x -2x
3 = 2x + 2
-2 -2
1 = 2x
Divide both sides by 2x
x = 1/2
<h2>Steps:</h2>
So for this, I will be completing the square to solve for x. Firstly, add 10 and subtract 30x on both sides of the equation:
Next, we want to make the left side of the equation a perfect square. To find the constant of this soon-to-be perfect square, divide the x coefficient by 2 and square the quotient. Once you get that result, add it to both sides of the equation:
Now, factor the left side:
Next, square root both sides:
Now, add 15 to both sides of the equation:
This is the <em>exact</em> solution. To find the approximate solution, solve the left side twice -- once with the plus sign, once with the minus sign:
<h2>Answer:</h2>
In short:
- Exact Solution:
- Approximate Solution (Rounded to the hundredths):
A whole number is a number that is whole as in 1,2,3,4,etc, they don’t have decimals. To find the whole number for these questions you must look at the places (hundreds, thousands, ten thousands.) I was always told a trick which is 4 or less let it rest, 5 or more let it sore. (Basically if it’s less than 4 then decrease it, if it’s higher than increase it.)
12.496 = 13
2.90 = 3
Your answers are 13 and 3.
The answer is 13, 4 x 2= 8 + 5= 13. therefore the answer is 2.13
Answer:Angela paid 679,05 for the couch
Step-by-step explanation:
425*70/100=29.750
29.750/100= 297,5
297,5+425=722,5
722,5*6/100=4.335/100=43,45
722,5-43,45=679,05
