a sixth grade class has 12 boys and 24 girls consider this statement: <br />for every two boys there are 4 girls do you ag
Nitella [24]
So the ratio of boys to girls is 12:24.. now, is that an equivalent ratio as 2 boys for 4 girls? or 2:4?  let's see.

\bf \cfrac{boys}{girls}\qquad 12:24\qquad \cfrac{12}{24}\implies \boxed{\cfrac{1}{2}}
\\\\\\
\cfrac{boys}{girls}\qquad 2:4\qquad \cfrac{2}{4}\implies \boxed{\cfrac{1}{2}}

you could start simplifying the 12/24 fraction by dividing by some common multiple, say 2, and get 6/12, then divide by 3 and get 2/4  and stop there.

then you'll notice that 12/24 is really 2/4 in disguise.

What is the solution to the equation?<br><br>√2x+10−6=2<br><br><br>*Picture of the Problem Below*
Klio2033 [76]

Answer:

x = 27

Step-by-step explanation:

Given

\sqrt{2x+10} - 6 = 2 ( add 6 to both sides )

\sqrt{2x+10} = 8 ( square both sides )

2x + 10 = 8² = 64 ( subtract 10 from both sides )

2x = 54 ( divide both sides by 2 )

x = 27
