Step-by-step explanation:

<u>Let's turn each mixed fraction into an improper fraction:</u>

2 \frac{1}{2} =\frac{2}{2} +\frac{2}{2} +\frac{1}{2} =\frac{5}{2}

3\frac{1}{5} =\frac{5}{5} +\frac{5}{5} +\frac{5}{5} +\frac{1}{5} =\frac{16}{5}

<u>Multiply:</u>

\frac{5}{2} \times \frac{16}{5} =\frac{80}{10}

<u>Simplify:</u>

\frac{80 \div 10}{10 \div 10} =\frac{8}{1} =8

8 is your simplified product.

Determine for what values of x and y are the following equalities always true.
Agata [3.3K]
(k+1)x-(2k+3)y-3k-5=0
kx + x - 2ky - 3y - 3k - 5 = 0
(x - 2y) k + (x - 3y) = 3k + 5

therefore
x - 2y = 3
x - 3y = 5

Subtract 2 equations
y = -2
x = -1
