x= -3/8

here's how you solve it!

first distribute the -2/3 into the parentheses and you'll get:

4-8/3x+6=11

Then add 4 and 6 together

10-8/3x=11

Then multiply the equation by 3

30-8x=33

Then move the constant to the other side and change the sign

-8x=33-30

Subtract 30 from 33

-8x=3

Then divide both sides by -8

x=-3/8

Then you are left with your answer:

x= -3/8

Hope this helps! :3

Simplify both sides of the equation.

4 −  2/3  (4x − 9) = 11

4 +  −8/3  x + 6 = 11

Distribute

(−8/3  x) + (4 + 6) = 11

Combine Like Terms

−8/3x+10=11

Subtract 10 from both sides.

−8/3x + 10 − 10 = 11 − 10

−8/3

x = 1  

Multiply both sides by 3/(-8).

(3/−8)*(−8/3  x) = (3/−8)*(1)

x =  −3/8

20. The figures are similar. Find x.
snow_tiger [21]

Answer:

10

Step-by-step explanation:

You can see that both triangles are the same except for one thing: one is smaller. Since 7 is half of 14 and both triangles are similar, x stands for 10. That is because 10 is half of 20! :D

Suppose you obtain a chi-square statistic of 67.81. Are your results statistically significant if the critical value obtained fr
Svetach [21]

Answer:

Result is statistically significant.

Step-by-step explanation:

Given that :

Chisquare statistic, χ² = 67.81

Critical value for the distribution, χ²critical = 3.84

α = 0.05

The Decison region :

If χ² statistic > Critical value ; Reject H0 ; this. Eans that result is statistically significant.

Therefore, since, 67.81 > 3.84 ; This means that the result is statistically significant at 0.05
