Answer:

Step-by-step explanation:

1/2r +1/2= -2/7r -29/7 Subtracting 1/2 from both sides

1/2r +1/2 - 1/2= -2/7r -29/7- 1/2

1/2r = -2/7r - 29(2)-7/14

1/2r = -2/7r -65/14

Answer:

$5.91430991*10^1^5$

Step-by-step explanation:

$4598\left(345+892\cdot \:231\right)\cdot \:5617\cdot \frac{1232+987}{2}\\=4598\cdot \:5617\cdot \frac{1232+987}{2}\left(345+206052\right)\\=4598\cdot \:5617\cdot \frac{2219}{2}\left(345+206052\right)\\=4598\cdot \:206397\cdot \:5617\cdot \frac{2219}{2}\\=\frac{2219\cdot \:4598\cdot \:206397\cdot \:5617}{2}\\=\frac{1.18286\dots E16}{2}\\=5.91431e15$
