Find five consecutive integers whose sum is 195.

Elodia [21]

X + (x + 1) + (x + 2) + (x + 3) + (x + 4) = 195

(Make sure you don't add "x+5" because "x + 0" is an included term.)

5x + 10 = 195
5x = 185
x = 37

Hope this helps!

Reika [66]

$\frac{8*( \frac{c}{c} )- \frac{3}{c} }{2*( \frac{7c}{7c})+ \frac{3}{7c} } \\ \\ \frac{ \frac{8c-3}{c} }{ \frac{14c+3}{7c} } \\ \\ \frac{8c-3}{c} * \frac{7c}{14c+3} \\ \\ = \frac{56c-21}{14c+3}$
