Eliminate the x and y

sp2606 [1]

Step-by-step explanation:

Eliminate the x:

$\left\{\begin{array}{ccc}x-2y=6\\3x+y=4\end{array}\right\\\\\text{Multiply by (-3)}\\\\\left\{\begin{array}{ccc}-3(x-2y)=(-3)(6)\\3x+y=4\end{array}\right\\\\\underline{+\left\{\begin{array}{ccc}-3x+6y=-18\\3x+y=4\end{array}\right}\\.\qquad\qquad7y=-14\\.\qquad\qquad y=-2$

Eliminate the y:

$\left\{\begin{array}{ccc}x-2y=6\\3x+y=4\end{array}\right\\\\\text{Multiply by 2}\\\\\left\{\begin{array}{ccc}x-2y=6\\2(3x+y)=(2)(4)\end{array}\right\\\\\underline{+\left\{\begin{array}{ccc}x-2y=6\\6x+2y=8\end{array}\right}\\\\.\qquad7x=14\\.\qquad x=2$

Find 4/7 divided by 7/8

Reika [66]

If you divide a fraction by another fraction, this is equivalent to mupltiplying by its inverse:

so $\frac{4}{7}$ divided by $\frac{7}{8}$

is equivalent to

$\frac{4}{7}$ multiplied by by $\frac{7}{8}$

which is

$\frac{4}{7}* \frac{7}{8}= \frac{4*7}{7*8}= \frac{4}{8}= \frac{1}{2}$

so the answer is $\frac{1}{2}$ which is also 0.5

Please Help solve this

Ok so to find the ratio just do 12/16 = 3/4. that's your common ratio.

The formula for sum of infinite :

a / (1 - r)

a is the first term and r is the ratio

which is

16 / (1 - (3/4))

which is

16 / (1/4)

16 * 4

which is 64
