If 3x / 4 = 7 - x / 3, then x = what?

Alja [10]

$\frac{3x}{4} = 7-\frac{x}{3} 

$
$\frac{3x*3}{4*3} = \frac{7*12}{12} -\frac{x*4}{3*4} 

$
$\frac{9x}{12} = \frac{84}{12} -\frac{4x}{12}$
$12*( \frac{9x}{12} = \frac{84}{12} -\frac{4x}{12} )$
$9x=84-4x
$
$13x=84$
$84/13$

30 POINTS!!!!!!

Answer: The sum that will be the upper limit of this population is 1280.

Step-by-step explanation:

Since we have given that

Initial population a₁ = 960

Common ratio = $\frac{1}{4}$

So, We have to write the sum in sigma notation:

$\sum (ar^{n-1})\\\\=\sum 960(\frac{1}{4})^{n-1}\\\\$

Since $r=\frac{1}{4}$

so, the sum is convergent, then,

$\sum 960(\frac{1}{4})^{n-1}=\frac{a}{1-r}=\frac{960}{1-\frac{1}{4}}=\frac{960}{\frac{3}{4}}=\frac{960\times 4}{3}=320\times 4=1280$

Hence, the sum that will be the upper limit of this population is 1280.

matrenka [14]

Answer: 4

Step-by-step explanation:

Melinda: y = 10x + 22

George: y = 13x + 10

13x + 10 = 10x + 22

-10x -10x

3x + 10 = 22

-10 -10

3x = 12

If you mean
3 times square root of 125 then go to AAA
if you mean ∛125 then go to BBBB

AAAAAA
3 times √125=3 times 5√5=15√5

BBBBBBB
∛125=5 or -5
