If 11 - 3x = x, then 20x=
dimaraw [331]

Answer:

20x = 55

Step-by-step explanation:

First you have to add 3x to both sides of 11-3x=x

11-3x=x\\+3x=+3x\\11=4x

Now that you have 11 = 4x you divide 4 on both sides \frac{11}{4} =\frac{4x}{4}

11/4 = x

But you can't divide 11 by 4 unless you are looking for the decimal form of 11/4 which is 2.75

so now we take 11/4 or 2.75 depending on if you need your answer in fraction or as a decimal and replace that with x  however both will equal the number 55

20(\frac{11}{4})=55\\20(2.75)=55

In his Fourth of July speech, Douglass says that "above your national, tumultuous joy, I hear the wail of millions.” To what is
krok68 [10]
I think that what Frederick Douglass meant by the "wail of millions" is that while the 4th of July is a great day to be celebrated by non-African American people as it meant the true independence of the 13 colonies from Great Britain and freedom for many of its citizens, in fact slavery is still intact at the time of his speech in 1852 and so July 4th cannot be celebrated by the vast majority of the black people in the US who are still under the terrible yoke of slavery.
