Y = 3/8(x + 4)....multiply both sides by 8/3, eliminating the 3/8 o the right
8/3y = x + 4....now subtract 4 from both sides
8/3y - 4 = x <==

n = m^2 - (n + 3)
n = m^2 -n - 3...add n to both sides
n + n = m^2 - 3
2n = m^2 - 3...add 3 to both sides
2n + 3 = m^2...take sqrt of both sides, eliminating the ^2
sqrt (2n + 3) = m or m = - sqrt (2n + 3) <==

Answer:

-1/11

Step-by-step explanation:

$\frac{11x}{12} -\frac{1}{6} =\frac{-1}{4}$ add 1/6 to both sides

$\frac{11x}{12} =\frac{1}{6} -\frac{1}{4}$ make the same denominator 12 on the right side

$\frac{11x}{12} =\frac{1}{6}*\frac{2}{2} -\frac{1}{4}*\frac{3}{3}$ solve

$\frac{11x}{12} =\frac{2}{12} -\frac{3}{12} =\frac{2-3}{12} = \frac{-1}{12}$

$\frac{11x}{12}*12 =\frac{-1}{12} *12$ multiply by 12 both sides

11x= -1 divide by 11

x= -1/11

7,080,267 written in expanded form

Alex787 [66]

If you know the definition of expand (to increase or make bigger)
then this will be easy.

when ever it asks for expanded for that means your answer has to be bigger than the number your given.

for your question:
you have 7,080,267

so u first do the biggest value which is the first 7 on the left.
and then work your way down to the smallest which would be 7 on the right.

7000000
000000
80000
0000
200
60
7
that is the numbers expanded

but now u have to write it in the fom so you just add a + after each number

7000000+000000+80000+0000+200+60+7
you can shorten it by removing the numbers with no value:
7000000+80000+200+60+7
