-2(6-x)= 3x, the solution is find the value of x, you must apply distributive property, tho the first term, -12+2x= 3x⇒ 3x-2x= -12⇒ x = -12, the answer correct is option D

The answer is "D" because after you distribute the -2 you must move the -2 to the other side and solve as normal

Two data sets have the same mean,

nirvana33 [79]

For Data Set B, we see that the data is more varied. The absolute deviations are 4, 3, 2, 5. The average of these absolute deviations is 3.5. MAD_B = (4+3+2+5)/4 =3.5 M ADB

Hence, The average of these absolute deviations is 3.5.

How do you solve and simplify 2/5+1/4+7/10=

Alchen [17]

Hello!

Answer: ⇒ 27/20

Step-by-step explanation:

$\frac{8}{20}+\frac{5}{20}+\frac{14}{20}$

Since the denominators are equal, then combine the fractions.

$\frac{8+5+14}{20}$

Add by the numbers.

$8+5+14=27$

$=\frac{27}{20}$

Hope this helps!

2^x=3^x+1 what are the exact approximate solutions

Mashcka [7]

Answer:

Step-by-step explanation:

The goal of course is to solve for x. Right now there are 2 of them, one on each side of the equals sign, and they are both in exponential positions. We have to get them out of that position. The way we do that is by taking the natural log of both sides. The power rule then says we can move the exponents down in front.

$ln(2^x)=ln(3^{x+1})$ becomes, after following the power rule:

x ln(2) = (x + 1) ln(3). We will distribute on the right side to get

x ln(2) = x ln(3) + 1 ln(3). The goal is to solve for x, so we will get both of them on the same side:

x ln(2) - x ln(3) = ln(3). We can now factor out the common x on the left to get:

x(ln2 - ln3) = ln3. The rule that "undoes" that division is the quotient rule backwards. Before that was a subtraction problem it was a division, so we put it back that way and get:

$x(\frac{ln(2)}{ln(3)})=ln(3)$ . We can factor out the ln from the left to simplify a bit:
