Expand

6 - 3x + 15 = 5x - 11

Simplify 6 - 3x + 15 to -3x + 21

-3x + 21 = 5x - 11

Add 3x to both sides

21 = 5x - 11 + 3x

Simplify 5x - 11 + 3x to 8x - 11

21 = 8x - 11

Add 11 to both sides

21 + 11 = 8x

Simplify 21 + 11 to 32

32 = 8x

Divide both sides by 8

32/8 = x

Simplify 32/8 to 4

4 = x

Switch sides

Answer:

4=x

Step-by-step explanation:

6-3(x-5)=5x-11

Distribute the -3

6 -3x +15 = 5x -11

Combine like terms

21 -3x = 5x-11

Add 3x to each side

21-3x+3x = 5x+3x-11

21 = 8x-11

Add 11 to each side

21+11 = 8x-11+11

32 = 8x

Divide by 8

32/8 = 8x/8

4 =x

Solve by factoring 6p^2 =21p-6

uysha [10]

Given,

The expression is:

$6p^2=21p-6$

By using the middle term splitting method,

$\begin{gathered} 6p^2-21p+6=0 \\ 2p^2-7p+2=0 \\ (x-(\frac{7+\sqrt{33}}{4}))(x+\frac{7+33}{4})=0 \end{gathered}$

Hence, the factor is (x-(7+sqrt(33)/4)) (x+(7+sqrt(33)/4)).

If one tosses a coin three times, write dow nthe possible observed number of heads and their probabilities

seropon [69]

You need to find the probability of Heads, Heads, Heads in 3 tosses;

P(HHH)= (1/2)(1/2)(1/2) <-- each toss has 2 possibilities and heads is one
P(HHH)=1/8

Therefore, the probability of flipping 3 heads on a fair coin is 1/8

Hope I helped :)
