Answer:

Given Equation : 1 + 2b - 13 = 12 - 4b - 2b

To write: Correct Steps to solve for b

In Step 1: We simplify constant in LHS.

⇒ 2b + ( 1 - 13 ) = 12 - 4b - 2b

⇒ 2b + ( -12 ) = 12 - 4b -2b

⇒ 2b - 12 = 12 - 4b - 2b

In Step 2: We simplify variable part in RHS

⇒ 2b - 12 = 12 + ( -4b -2b )

⇒ 2b - 12 = 12 + ( -6b )

⇒ 2b - 12 = 12 - 6b

In Step 3: We transpose 6b of RHS to LHS

⇒ 2b - 12 + 6b = 12

In Step 4: Now simplify variable in LHS

⇒ 2b + 6b - 12 = 12

⇒ 8b - 12 = 12

In Step 5: Transpose 12 to RHS

⇒ 8b = 12 + 12

In Step 6: Simplify constants in RHS

⇒ 8b = 24

In Step 7 transpose 8 to RHS

\implies\:b\,=\,=\frac{24}{8}

In Step 8: Simplify RHS

⇒ b = 3

A marble is selected at random from a jar containing 3 red​ marbles, 4 yellow​ marbles, and 6 green marbles. What is the probabi
alexgriva [62]

Answer:  a) \dfrac{3}{13},\ b)\dfrac{9}{13}\ c)\dfrac{9}{13},\ d)\dfrac{4}{13}

Step-by-step explanation:

Since we have given that

Number of red marbles = 3

Number of yellow marbles = 4

Number of green marbles = 6

Total number of marbles = 3 +4 +6 = 13

​a) the marble is​ red? ​

Probability of getting a red marble = \dfrac{3}{13}

b) the marble is not​ yellow?

Probability of not getting yellow = \dfrac{3+6}{13}=\dfrac{9}{13}

​c) the marble is either red or ​green?

Probability of getting either red or green = P(red) + P(green) =\dfrac{3}{13}+\dfrac{6}{13}=\dfrac{9}{13}

d) the marble is neither red nor ​green?

Probability of getting neither red nor green = P(getting yellow) = \dfrac{4}{13}

Hence, a) \dfrac{3}{13},\ b)\dfrac{9}{13}\ c)\dfrac{9}{13},\ d)\dfrac{4}{13}

Use the zero product property to find the solutions to the equation 6x^2 – 5x = 56.
frez [133]

Answer:

x = 7/2 or x = -8/3

Step-by-step explanation:

Solve for x over the real numbers:

6 x^2 - 5 x = 56

Divide both sides by 6:

x^2 - (5 x)/6 = 28/3

Add 25/144 to both sides:

x^2 - (5 x)/6 + 25/144 = 1369/144

Write the left hand side as a square:

(x - 5/12)^2 = 1369/144

Take the square root of both sides:

x - 5/12 = 37/12 or x - 5/12 = -37/12

Add 5/12 to both sides:

x = 7/2 or x - 5/12 = -37/12

Add 5/12 to both sides:

Answer:  x = 7/2 or x = -8/3

Is 3:4 equivalent to 12:24
Nuetrik [128]
No because 3 times 4 is 12 but 4 times four is 16 and TO get from 4 to 24 you multiply 6 but 6 times 3 is 18 so no I think
