\sqrt{41 -  \sqrt{21 +  \sqrt{19 -  \sqrt{9} } } }  \\  =  \sqrt{41 -  \sqrt{21 +  \sqrt{19 - 3} } }  \\  =  \sqrt{41 -  \sqrt{21 +  \sqrt{16} } }  \\  =  \sqrt{41 -  \sqrt{21 + 4 } }  \\  =  \sqrt{41 -  \sqrt{25} }  \\  =  \sqrt{41 - 5}  \\  =  \sqrt{36}  \\  = 6

saw5 [17]

Answer:

The absolute value inequality to represent the situation is presented as follows;

\left | w -400  \right |

Step-by-step explanation:

The given information are;

The number of words Annika needs to write = 400 words

The absolute deviation of the number of words Annika needs to write = 10 words

When we let the number of words Annika write = w, we have;

The absolute value inequality given that the absolute deviation of the number of words is 10 is given as follows;

\left | w -400  \right |

Therefore we have;

\left | w -400  \right |  gives the statement, -10 < w - 400 < 10.

There are as many girls as there are boys in a class. 8 girls went for a dance competition. now there are twice as many boys as
Rashid [163]
Let the number of girls be x and the number of boys be y

The number of boys is the same as the number of girls.
x = y 
The number of boys is twice the number of girls when 8 girls left.
2(x - 8) = y


x = y ---------------- (1)
2(x - 8) = y -------- (2)

Sub (1) into (2)

2(y - 8) = y
2y - 16 = y
2y - y = 16
y = 16
There were 16 boys and 16 girls initially.

16 + 16 = 32 
There were a total of 32 students in the class initially.
