We need to solve the problem.

\dfrac{-1}{3}\times \dfrac{2}{5}=\dfrac{-1\times 2}{3\times 5}\\\\=\dfrac{-2}{15}

Please help! <br> 70+23x-5+110+14x=360 (please show step bc I need to turn in work-paper) Thank you!
daser333 [38]

x = 5

<u>explanation</u>

70 + 23x - 5 + 110 + 14x = 360

first you group the like terms

23x + 14x + 70 - 5 + 110 = 360

then combine the like terms

<u>23x + 14x</u>    <u>70 - 5 + 110</u>

37x + 175 = 360

subtract 175 from both sides

175 - 175 = 0     360 - 175 = 185

to get

37x = 185

divide both sides by 37

37x/37 = 0     185/37= 5

which gives you

x = 5
