What is the value of x? 3x - x + 4 = 4(2x - 1)

1 answer:

8 0

3x−x+4=4(2x−1)
Step 1: Simplify both sides of the equation.3x−x+4=4(2x−1)Simplify: (Show steps)2x+4=8x−4Step 2: Subtract 8x from both sides.2x+4−8x=8x−4−8x−6x+4=−4Step 3: Subtract 4 from both sides.−6x+4−4=−4−4−6x=−8Step 4: Divide both sides by -6.−6x/−6=−8/−6x=4/3Answer:x=4/3

Olegator [25]

Answer:

(a) 74553

(b) 172120

Step-by-step explanation:

Given

$y = \frac{340110}{1 + 377e^{-0.259t}}$

Solving (a): 1998

Year 1998 means that:

$t =1998 - 1980$

$t =18$

So, we have:

$y = \frac{340110}{1 + 377e^{-0.259*18}}$

$y = \frac{340110}{1 + 377e^{-4.662}}$

$y = \frac{340110}{1 + 3.562}$

$y = \frac{340110}{4.562}$

$y = 74553$ --- approximated

Solving (b): 2003

Year 2003 means that:

$t = 2003 - 1980$

$t =23$

So, we have:

$y = \frac{340110}{1 + 377e^{-0.259*23}}$

$y = \frac{340110}{1 + 377e^{-5.957}}$

$y = \frac{340110}{1 + 0.976}$

$y = \frac{340110}{1.976}$

$y = 172120$ --- approximated

Solving (c): 2006

Year 2006 means that:

$t = 2006 - 1980$

$t =26$

So, we have:

$y = \frac{340110}{1 + 377e^{-0.259*26}}$

$y = \frac{340110}{1 + 377e^{-6.734}}$

$y = \frac{340110}{1 + 0.4485}$

$y = \frac{340110}{1.4485}$

$y = 234802$ --- approximated

Solve for w pls help thank u

masya89 [10]

Answer:

w = -19

Step-by-step explanation:

-6w + 4(w +3) = 26

-6w + 4w + 12 = 26

simplify

-2w + 12 = 26

now get the variable and the numbers on different sides

-2w + 12 - 12 = -2w

26 + 12 = 38

-2w = 38

now divide each side by -2

-2w / -2 = w

38 / -2 = -19

w = -19

Five less than twice a number is equal to 57

Sliva [168]

The easiest way to do this is to break it down and translate it before solving. Start with twice a number, if you use n to represent eh number, you will have 2n. Then, add the 'less than' part. 'Five less than' means that five is being subtracted from the next part, which is 2n. Now you have 2n - 5. The last translation is simple, 'equal to 57' will complete the equation as 2n - 5 = 57.
If you want to solve the equation, use the Order of Operations.

2n - 5 = 57 Add 5 to both sides
2n = 62 Divide both sides by 2
n = 31
