Answer:

$5 {x}^{2} + 2x = 7x + 3x \\ 5 {x}^{2} + 2x = 10x \\ 5 {x}^{2} = 10x - 2x \\ 5 {x}^{2} = 8x \\ 5x = 8 \\ x = \frac{8}{5} = 1.6 \\ thank \: you$

Which number has the same value as 3 X 1/10?

irakobra [83]

To find the same value as 3 x 1/10 you first have to solve 3 x 1/10

so how to do this is you have to make 3 into a fraction

so to make 3 into a fraction you can put 3 as the numerator and 1 as the denominator

so you multiply
$\frac{3}{1} \times \frac{1}{10} = \frac{3}{10}$
so 3/10 has the same value as 3x1/10

HOPE THIS HELPS!!!
